East and West. Maybe it is not easy to draw straight lines where these two are clearly separated, and yet everyone has a conceptualization of what is meant when this distinction is proposed. While some circles try to delineate the differences and polarize societies on the basis of “us vs. them,” there are others who prefer to highlight commonalities, shared pains and joys, the benefits of interaction, and an inevitable future of less separation and more coexistence.

One dynamic of our shared society that will shape such a future is migration. Migration is a reality of the human condition. Throughout history, migrations, be they mass or individual movements, have not only shaped our societies, national borders, languages, religious traditions, and of course, identities, but have also been a major catalyst for disputes and conflicts. Hence, for the last several years, the US has been debating whether a wall should be built across the Mexican border; we continue to watch the heart-breaking tragedy of thousands of refugees rowing across the Mediterranean; the ongoing plight of Syrians fleeing their country’s violence; and more recently, the forced migration of teachers, doctors, and civil servants affiliated with the Hizmet Movement from Turkey, their homeland, where they have suffered persecution for the last few years. Due to many reasons, including geographical, historical, and colonial ties, Europe has been one of the major destinations for those seeking freedom and a life of security, especially for many Muslims. Akbar Ahmed’s book Journey into Europe: Islam, Immigration and Identity (2018) is one of the most comprehensive researches into this very complex social phenomenon. In this issue, Behzad Fatmi from India reviews Ahmed’s book and explains how the author dissects the fundamental character of European society vis-à-vis the place of Muslim communities in the continent.

Learning theoretically about diseases is surely important. But having a first-hand experience, or at least spending time with those who suffer from a disease, teaches much more than what one can learn from books. Ceyda Sablak shares her experience with some patients who told what they have been through with Amyotrophic Lateral Sclerosis (ALS). She writes how important it is to have an accurate and concrete diagnosis, even if it turns out to be a terminal illness. While it is painful to go through such an illness, it is no less of a burden on the shoulders of doctors and the family who have to be present next to their loved ones and do as much as they can to continue to care for them.

But our similarities and differences can also be much more significant, as well. On one hand, for instance, the tenth anniversary of 9/11 was a major occasion for the U.S., but for a great majority of the world it was just a single chapter-albeit a long one-in the chronicles of violence in human history. On the other hand, almost every nation today from the Philippines to Nigeria has diverse security issues, and in many countries mass killings, violent attacks, and explosions have become astonishingly unastonishing. Just before the turn of the year, for instance, terrorism showed its monstrous face once again against Christians observing Christmas in Nigeria. Indeed, these attacks were an unprecedented form of violence by so-called Islamic terrorists-where in the history of Islam can one show violence against Christians as they are worshipping, especially when the Qur’an and the Prophet forbade harming worshippers in churches or monasteries? Is there any permission in Islam to attack civilians? Iraq and Syria have their own fashion of violence: sectarian conflicts in the fight for obtaining the right to rule. There are many major concerns that all human beings share, and this calls for developing a common understanding so that we can tackle them together. In all of the events The Fountain organizes, we try to raise awareness of our commonality by cultivating an environment in which we can learn from our differences.

The lead article in this issue underlines one dimension of one of our universal humanness by relating “happiness” to “virtue.” The article on autism tries to open a window of hope for families suffering from this really difficult ordeal. In “The Optimizing Man,” you will read on the many economic irrationalities we commit for the sake of transient fancies. The article on cultural differences shares with us some interesting differences between varying nations of the world with memorable examples. De Villa guides us on an exploration of the fantastic civilization of Al Andalus, an exemplary era of coexistence in human history.

New Jersey-based Helping Hands Relief Foundation (HHRF) is one of those relief organizations that have quickly responded to the call for help from the Horn of Africa. Many volunteers of HHRF have already taken off to Somalia to deliver donations and food to the victims.

The world is undergoing several major tests. The problems caused by economic crises one after another, terrorism, global warming, and others have to be tackled with immediately. But the emergency of the current famine has no comparison, and we have to act now. It is time to delay our own needs today and rush for help to the victims of the famine. This is the greatest test we as the human family have to be pass.

The month of Ramadan is an opportunity to put free will to a test for Muslims across the world. By fasting from dawn to sunset, Muslims do not only stay away from food, they are also expected to attain the most virtuous conduct by being generous in the heart as well as in charity, by shutting off their mind sand tongues to evil thoughts and words, and by appreciating every bit of food and water, the value of which we normally ignore. The Questions and Answers section in this issue focuses on this blessed month with a special emphasis on habitualizing the discipline we become accustomed to during Ramadan.

Ramadan is also a time for realizing the differences among multicultural societies. Many Muslims invite their non-Muslim neighbors to share fast-breaking dinners with them. Trish Madigan, a Dominican sister from Australia, illustrates how much she has learned from Islam in her article on such occasions, and she stresses that there are many issues that both Muslims and Christians can “resonate with” if they step forward to explore each other’s faiths.

Another example of sharing comes from Abdullah Aymaz. In his article, Aymaz recounts an interesting story of Ottoman donations to the Irish people who were desperately suffering due to the Great Hunger in the 1840s. The Ottoman sultan, not daunted by political or logistical obstacles, or the long distance,sent five ships full of food to Ireland. This act of charity is still being commemorated in gratitude by the Irish. This article narrates a great example of a humanitarian service in which no discrimination sullied the feeling of sharing.

This month’s issue also contains remarkable topics from biology, astronomy, and physics. In “Hearing for Deaf Ears” we will learn how the ear functions

and discover a new technology for those who cannot hear: Cochlear Implant (CI) systems. In “What Makes Planets Revolve Around the Sun” we will be presented with interesting data about solar activity, and in “Thoughts on Matter and Anti-Matter” we will be taken on a thought-provoking journey in atom.

We wish you a blissful Ramadan.

Wolf (1999) notes that a nonprofit organization is neither in the profit sector nor in the public sector but sits somewhere between the two. This position allows the nonprofit great flexibility in its operation but requires great skill in its management. Nonprofit organizations have characteristics of profit and public organizations. Wolf defines nonprofit organizations as “those legally constituted, nongovernmental entities incorporated under state law as charitable or not-for-profit corporations that have been set up to serve some public purpose and are tax exempt.” All nonprofit organizations must have the following characteristics:

• They must have a public service mission-their main goal must be to serve others, not themselves.

• They must be organized as a not-for-profit or charitable corporation-they must formally claim to be non-profit.

• Their governance structure must preclude self interest and private financial gain-this goes back to the first characteristic in that the organization’s main goal is to serve people.

• They must be exempt from paying federal tax.

• They must possess the special legal status that stipulates gifts made to them are tax-deductible.

It is obvious that the nonprofit sector has expanded dramatically over the past few years, so has public scrutiny over the sector. Governance is needed to ensure that the organization is providing services that are permitted within the legal system and the bylaws and to ensure that the organization does not permit fraud, potential abuse, and violations of the expectations of the public. Governance of a nonprofit can be defined as the ultimate authority, accountability, and responsibility for an organization (Ott 2001). Leadership, such as the board, is important in the nonprofit sector because it is governed through a complex set of functional roles and procedures that are defined in laws and tax codes that differ from those for the public and for-profit sector. The board is responsible for policies, procedures, financial outcomes, and ensuring that the mission of the organization is being implemented and accomplished to the best of the organization’s ability to serve its target population or general public.

There are some challenges that nonprofit organizations face in our modern societies. The first major challenge for a nonprofit organization is articulating a clear public service mission. A nonprofit organization is required by law to limit its activities to those articulated in the mission statement, so the mission statement must be broad enough to cover all possible activities. The mission statement must also guide the direction of the organization’s programs, services, and activities. In addition, a mission statement may require review and revision over time. For example, an arts council can begin with a mission to develop, foster, and promote the arts, and then develop a stronger mission statement that provides detailed plans for programs and activities, such as working with the school district to develop art education programs, and seeking funds from state, federal, and private sources.

The second major challenge is risk/survival analysis: the search for the proper balance between organizational extension and risk-taking, and organizational security. Engaging in risk/survival analysis means having an understanding of what should and should never be compromised, always being cognizant of the mission and whether or not daily activities or decisions are in harmony with that mission. This challenge identifies a great dilemma for nonprofit organizations: whether it is more important to ensure survival of the organization or to stay true to the mission. There is no easy answer. To meet this challenge, the organization must continually plan, analyze future options (both practical and idealistic), and debate the pros and cons of each option.

The third major challenge facing a nonprofit organization is constituency identification and involvement. Identifying and involving the constituency entails having a working knowledge of the clientele you desire to serve. This must not be too narrow or too broad. The nonprofit organization must establish a concise identification of its constituency in order to avoid problems in this area. The organization must identify the group that it seeks to serve, and then must create a structure that supports a commitment to that group. To meet this challenge, the organization must have a well-defined understanding of its constituency, seek to involve the constituency at all levels of the organization (particularly at the trustee level), and provide programs and activities that reflect a commitment to the constituency.

The fourth major challenge is testing for organized abandonment: that is, disbanding that is the result of careful deliberation, rather than unplanned events, such as financial crisis or management problems. In order to meet this challenge, the organization must have a clearly defined mission, establish criteria for evaluation of the mission, and have a formal system to determine whether or not the mission is relevant and effective. The organization must examine whether or not its mission is obsolete or if other organizations are more effective in achieving its mission.

In conclusion, nonprofit organizations go where other organizations fear to tread. Nonprofits eagerly work with the most disadvantaged members of society-the homeless, the hungry, the ill, and the befuddled. Nonprofits fill the gaps in society-consider the thousands of charter schools that have sprung up to provide a genuine alternative, most frequently for students from disadvantaged backgrounds. Nonprofits extend and even function as government service-providers: how would most governmental social service agencies function if not by contracting out to tens of thousands of nonprofit service providers. Think too of the thousands of neighborhood associations that knit together their communities, and sometimes act indistinguishably from chartered governments. Nonprofits help people find meaning-both through quiet worship and organizing millions of people to do “good deeds.” People who want to “do something, to give back to society” sometimes do so through governments, but most do so through nonprofits. Millions of volunteers contribute and share in the nonprofit sector. Finally, unlike the other sectors, the nonprofit sector does not start out by asking how much money can be made, or where the money is going to come from; no, the nonprofit sector asks what the need is and how to fulfill the need. Only then does it seek strategies to support the social needs it discovers. Although by nature humble, it is the nonprofit sector that makes our complex and frequently materialistic and even selfish society, humane, purposeful, and cohesive. The private sector may provide the engine of growth and a quality of life; the public sector may organize us and keep the private sector in line; but it is the nonprofit sector that is our heart, our soul, and our spirit as a society.

Both festivals are meant to serve different aspects of Islam; however, visiting cemeteries is one special component of these festivals which is carried out in the early hours of the first day. Right after the prayer, people leave the mosques and head to the graveyards. In a few minutes, the traffic is blocked in the overcrowded streets of major metropolises like Istanbul; but this time, however, the drivers manifest a phenomenal forbearance that is not to be seen on a normal day. Life and death meet one another as the living visitors stand by their host’s underground residences.

“Istanbul’s Vanished City of the Dead” depicts a cemetery which, although it does not exist today, exemplified the “cemetery culture” of a cosmopolitan Istanbul until just over one hundred and fifty years ago. “The Grand Champs des Morts was one of the world’s great necropolises with burial grounds for followers of both Islam and Christianity in close proximity. A realm where the living intermingled with the dead, it roused the interest and imagination of visitors to Istanbul, and, even more notably, in an age of reform and change, offered inspiration and a model for contemporary designers of cemeteries in Western Europe.” Many travel accounts and historical sources are cited in the article, with engravings portraying the now vanished necropolis.

The lead article, “Beauty and the Beautiful,” refreshes our perception of the world we live in and of the life we experience. All of creation is in complete harmony and is like a perfectly bound book, displaying every kind of beauty at the turn of each page. Most of us, however, become immersed in daily activities and cannot easily find access to these beauties; our daily engagements present a great obstacle between us and this level of insight. Only the light of belief enables us to realize how fortunate we are for having been granted the capacity to observe and reflect upon this beautiful existence: “Who created the seven heavens one above another; you see no incongruity in the creation of the Beneficent God; then look again, can you see any disorder?” (Mulk 67:3).

Women in politics

I attended a lecture by Iceland’s Olof Olafsdottir, who is the head of the division for Equality between Women and Men at the Council of Europe a very long title to carry along with the heavy responsibilities that follow

The topic was women in politics in the 43 Council of Europe member states. First of all, it is worth noting that voting rights for most European women were achieved only after World War I (1919 for the US). Statistics on the percentage of women in the government are extremely astonishing,1 although the trend is rather expected. As we move toward southern and eastern Europe, the female percentage decreases. Sweden, Finland, and Norway, are at the top of the list. Half of all Swedish government officials are women. On the other hand, Italy has only 8%, the lowest among European Union member countries.

Certain countries have undertaken serious reforms to increase female participation. For instance, Spain moved up to 21% when, in the post-Franco era, women took advantage of the rebirth of democracy. France, the symbol of equality, fraternity, and liberty, recently reformed its constitution to grant equal opportunities for women to participate in politics. Even though women had the right to vote and be elected since 1949, the French government was only 27% female as of 2001.

Political systems are a major factor. If political parties and politicians have too much power, the competition is tougher. As a consequence, it is believed that women find it too difficult to deal with process as well as with the power of the positions. Turkey and France are perfect examples of this phenomenon, and so women are likely to be discouraged by the ensuing harsh power struggle.

Paternal leave for fathers

Why does the decision-maker’s gender make a difference? Many people might pose this question. The most current and concrete answer is the case of Sweden, where 50% of the decision-makers are women. A paternal leave law exists in many democratic countries. However there is a major flaw almost all cases only the mother uses her paternal leave while the father does not interrupt his career. The Swedish Parliament passed a law offering a month-long paternal leave to the father that cannot be passed on to the mother. As a result, many fathers who had used the excuse that their jobs were more important and any interruption would be considered a major reversal suddenly decided to use this opportunity to be with their new-born children!

Another major result of the high female presence in the Swedish Parliament is the seen in legislation related to prostitution: both the prostitute and the customer are punished!

Cultural reasons for lower political participation in Muslim countries

Two related factors can account for the major gap between countries having high and low rates of women in their governments: democratic identity and culture. Efficient and older democracies have established a real democratic culture in which individuals are valued and politics is close to the people. Also, culture tends to affect the role of men and women immensely. For instance, Turkish women are very powerful in the household. The division of duties has developed according to Islamic teachings, which assigns specific social roles to men and women according to their nature. Women are more emotional, intuitive, and affectionate, and so are more fit to run the family and the household and to educate the children. Men, on the other hand, are responsible for struggling outside the house to maintain the family. Thus, in most Muslim-majority countries the percentage of women in politics is rather low. However, as the family structure is very strong, fewer social problems are observed.

Gender Equity in Qur’an

It was hard for me to accept this view until I realized that, according to the Qur’an:

– Men and women have the same spiritual human nature.

– Both genders received the divine breath, for they were created with the same human and spiritual nature.

– Both genders are dignified and are trustees of Allah on Earth.

– Woman is not blamed for humanity’s fall. Pregnancy and childbirth are not seen as punishments for eating from the forbidden tree. On the contrary, the Qur’an considers them to be grounds for love and respect due to mothers.

– Men and women have the same religious and moral duties and responsibilities, and both face the consequences of their deeds.

– The Qur’an does not state that one gender is superior to the other. Some mistakenly translate qiwamah (responsibility for the family) as superiority. The Qur’an makes it clear that the sole basis of superiority is piety and righteousness instead of gender, color, or nationality.

– The absence of women as Prophets or Messengers of Allah is due to the demands and physical suffering associated with such figures’ roles, not because of any spiritual inferiority.2

Conclusion

There is no evidence from the Qur’an to preclude women from leading a state. Islam does not forbid or discourage the education of women. On the contrary, Islam authorizes women to have careers in fields such as teaching and medicine. However, a woman’s most essential responsibility is to educate her children and raise a sound family. Raising children is a key social function, for a society’s future and efficient functioning depends on educated generations. Thus, from this perspective, a woman’s responsibility is rather significant and challenging.

I hope that those who are having a hard time with gender equality in Islam take the time to do a little research, because the most logical and convincing answers are there to be discovered.

So-called ‘new’ viruses most probably derive from existing viruses; in general, viruses of today have ancestors and relatives. However, as viruses show great variety, and many of the viruses of gravest concern mutate rapidly and unpredictably, it is not always possible to trace their ancestry with any great confidence. A ‘new virus may be genuinely new or a major evolutionary variant arising from genetic processes such as mutation or recombination. Their rate of mutation is so high that controlling them, or predicting their behaviour, is well-nigh impossible. High mutation rate means that no RNA (ribonucleic acid) virus population is a single entity, but rather a ‘quasi species’. Introduction of a virus from one species to another and dissemination from a smaller to a larger population are also among the basic mechanisms by which viruses emerge.

The emerging viruses are surfacing from ecologically damaged parts of the earth. When viruses come out of an ecosystem, they tend to spread in waves through the human population. Among the most notorious are: Lassa, Rift Valley, Oropuche, Rocio, Q. Guanarito, VEE, Monkeypox, Dengue, Chikunganya, the Hanta viruses, Machupo, Junin, the rabies like strains Mokola and Duvenhage, LeDantec.

AIDS: Acquired Immunodeficiency Syndrome

Human immunodeficiency virus (HIV) is a more difficult case compared to, for example, influenza, itself a great killer – the influenza pandemic of 1918-9 in China caused some 20 million fatalities. We do not know the origin of HIV, but a probable primate origin is often suggested, and appears highly plausible. HIV-2 (one of the major strains of HIV) may be a mutant that jumped into humans from an African monkey known as the sooty mangabey, perhaps when monkey hunters or trappers touched body tissue. HIV-1 (the other strain) may have jumped into man from chimpanzees – perhaps when hunters butchered chimpanzees.

HIV attacks the type of lymphocytes known as helper T-cells that stimulate the activity of B lymphocytes that produce antibodies. After an HIV infection sets in, helper T-cells begin to decline in number and the person becomes more susceptible to infections.

The AIDS virus mutates rapidly and constantly. It is a hyper-mutant, a shape-shifter, spontaneously altering its character as it moves through individuals. It mutates even in the course of one injection.

The drug AZT has been found to be helpful in prolonging the lives of AIDS patients. Also, it has been shown that administration of Interleukin-2 and AT-538 can prevent viral replication in cells in the early stages of the infection.

The Filoviruses

Marburg and Ebola viruses were recently elevated to family status as the Filoviridae. The name, ‘thread viruses’, is based on their morphology. These viruses made their appearance in the 1960s and 1970s in the form of frightening nosocomial and occupational outbreaks, initially among polio vaccine production workers in contact with Ugandan green monkeys and their kidney tissues, then in independent hospital epidemics of devastating proportions during 1976 in the Sudan and Zaire. Mortality from these infections can range to nearly 90%, that is 90% of infections, not just of clinical illnesses.

The incubation period of a filovirus in a human being, is from 3 to 18 days during which time the number of virus particles climbs steadily in the bloodstream. Then the suffering begins.

Marburg was the first filovirus to be discovered. It erupted in a factory producing vaccines using kidney cells from African green monkeys. Thirty-one people caught the virus. Seven infected persons died in pools of blood in just two weeks. This fatality rate of one in four makes Marburg an extremely lethal agent, yet it is the mildest of the filoviruses. No vaccine is available.

Ebola Sudan

The next indication of the existence of filoviruses came from an extraordinary pair of epidemics in 1976. In the Sudan the initial focus was a cotton factory in Nzara, and several of the earliest recognized cases worked there in a single room. Travel to nearby Maridi introduced the virus into the medical care system, with subsequent latrogenic dissemination that devastated the Maridi hospital. In this outbreak, 150 out of 280 infected people died.

In 1979, it recurred in Nzara, Sudan. The index case had worked in the same room in the cotton factory identified in the earlier epidemic. Twenty-two out of 34 infected patients died. When it first erupted, the medical stuff had used dirty needles which facilitated the spread of infection. Again, no vaccine is available.

Two months after the start of the Sudan emergence in 1976, an even more lethal filovirus emerged. The Ebola Zaire, a new strain was nearly twice as lethal as Ebola Sudan. The fatality rate of Ebola Zaire is 9 out of 10. Staff at a hospital which had been at the epicenter of the epidemic were almost all wiped out: 13 out of 17 of the doctors and nurses died. The disease erupted more or less simultaneously in fifty-five villages near the headwaters of Ebola River.

This epidemic was clearly dependent on the use of unsterilized needles and syringes for its major dissemination between villages, although multiple later generations of cases occurred among family contacts without any defined exposure route.

Ebola is distantly related to measles, mumps and rabies. It is also related to certain pneumonia viruses, to the parainfluenza virus which causes colds in children, and to the respiratory syncytial virus, which can cause fatal pneumonia in a person who has AIDS.

Ebola kills a great deal of tissue while the host is alive. It triggers a creeping, spotty necrosis that spreads through all the internal organs. The liver bulges up and turns yellow, begins to liquefy and then it cracks apart. The kidneys become jammed with blood clots and dead cells, and cease functioning. As the kidneys fail, the blood becomes toxic with urine. No vaccine is available.

Ebola does in ten days what it takes AIDS ten years to accomplish. In principle Ebola-like viruses could spread out all over the world in just one month and a half. Richard Preston, the author of Hot Zone argues that AIDS may be the first step in a natural process of clearance. What is being cleared is human beings: the earth’s immune system, so to speak, has recognized the presence of our species and is starting to kick in and signal its potential to rid itself of an infection by human beings. There can be no excuse for failing to reflect radically on the way we manage our economies, our societies and our lifestyles. We have no absolute right of tenure of this planet, nor does our collective intelligence or our science and technology afford a reliable immunity from vulnerability, whether as individuals or as a species. We do need to be fearful perhaps, though not to panic – so that we redress the balance in favour of humility in our attitudes and activities, so that we become more caring and careful in using our God-given faculties to prevent the worst before it happens.

Because of their biochemical importance, the nucleic acids receive much more attention than the others. DNA was first isolated in 1869 by F. Miescher from cell nuclei. Nearly 80 years of research have been carried out to identify the major building block units and the basic structure of nucleic acids. DNA molecules from different cells and viruses vary in ratio of the four major types of nucleotide monomers, in their nucleotide sequence, and in their molecular weight. Four major bases (adenine, guanine, thiamine, and cytosine) are found in all DNA. The DNA isolated from different organisms and viruses normally has two strands in complementary double-helical arrangement, and it is the basic compound of genetic material (chromosomes). In its double-helical structure it has a 20 A (1 A=10-8 cm) diameter width and the nucleotides are repeated in every 3.4 A.

This polymeric molecule, DNA, is the chemical basis of heredity and is organized into genes, the fundamental units of genetic information. It was first demonstrated in 1944 in a series of experiments that genetic determination of the character (type) of the capsule of a specific pneumococcus could be transmitted to another of a distinctly different capsular type by introducing purified DNA from the former coccus into the latter. This agent (later shown to be DNA) was called ‘transforming factor’. Subsequently ,this type of genetic manipulation has become commonplace. Similar experiments have recently been performed utilizing yeast, cultured mammalian cells, and insects and rodents as recipients, and cloned DNA as the donor of genetic information.

DNA has the ability to replicate itself. It is this property that holds the genetic material in the same type and number sequence during the cell divisions. In prokaryotic cells, which contain only a single chromosome, essentially all the DNA is present as a single double-helical, two-stranded macromolecule exceeding 2 x 10- 9 in molecular weight. In eukaryotic cells, which contain either several or many chromosomes, there ate either several or many DNA molecules. 

The double-stranded structure of DNA can he melted in solution by increasing the temperature or decreasing the salt concentration. The denaturation of DNA is used to analyze its structure. Not only do the two stacks of bases pull apart but the bases themselves unstack while still connected in the polymer by phosphodiester backbone.

Careful examination of the model reveals a major groove and a minor groove winding along the molecule parallel to the phosphodiester backbone. In these grooves,proteins can interact specifically with exposed atoms of the nucleotides (usually H bonds) and thereby recognize and hind to specific nucleotide sequences without disrupting the base pairing of the double-helical DNA molecule. As easily seen, regulatory proteins can control the expression of specific genes via such interactions.

The genetic information stored in the nucleotide sequences of DNA serves two purposes. It is the source of information for the synthesis of all proteins of the cell and organism, and it provides the information inherited. Both these functions require that the DNA molecule serve as template – in the first case for the transcription of the information into RNA and in the second ease for the replication of the information into daughter DNA molecules.

DNA is likely to survive for millions of years in some conditions. Amber can provide some of the right conditions to preserve DNA. The most reliable report of DNA to date from amber is that of termite-like sequences from around 30 million year-old Dominican amber. The earlier recovery of DNA from a 20 million year-old magnolia leaf, near Moscow, was more remarkable because the leaf was preserved in a sequence of easily split soft clays and silts, interbedded with layers of volcanic ash.

Recent developments in genetics are providing very powerful new techniques for the analysis of DNA from remains of ancient organisms. The young field of ancient DNA research is less than a decade old but is growing exponentially. In spite of some serious technical difficulties, the study of ancient DNA promises to become a revolutionary research tool in archaeology; anthropology and molecular biology.The earliest report of retrieval of informative DNA sequences from extinct animals – in this case from the desiccated skin of a quagga, a member of the horse family which became extinct more than one hundred years ago – was that by A. Wilson and his colleagues in 1984. Shortly after this, DNA was isolated by S. Pbo from the skin of a pre-dynastic Egyptian mummy; it was shown by DNA hybridization that a small amount of recognizable human DNA was left in the ancient tissue. In 1988, the first report of an amplified ancient DNA sequence was made by S. Pbo and colleagues who retrieved it from a 7,000 year-old skull found in a peat bog.

It seems likely that studies of this kind will become even more popular in the near future. With the ancient DNA sequence studies, one of the most controversial problems in biology – evolution – will possibly be enlightened. No there is a drive to gather genetic information from indigenous groups to increase our understanding of human origins, history and migrations. Ancient DNA studies will play a very important role by providing a direct source of objective evidence on past populations, and perhaps the only reliable insight into the genetic characteristics of vanished peoples.
