The answer was interesting and had deep meanings, but still left questions in my mind. The creatures were told: a new species will be created and arrive soon, and each member of this species will be equivalent and worthy of a whole species.

Those who asked the question were silent, suggesting they were satisfied with the answer. But I wondered how a single member of a species can be worth an entire species – and whether destroying a whole species for a new one can really be just.

Here, it was obvious to me that the new species that would be created is humans, and those condemned were the species who went extinct in ancient times, before humanity appeared on earth. This dream vaguely reminded me something that I read in the “Risale-i Nur Collection” by Bediuzzaman Said Nursi.

Bediuzzaman remarkably states that, “A human being is equivalent to a species of other creatures” (Zuhra – 4th point, Isharat al-I’jaz, and Mathnawi al-Nuriya). This line hadn’t really struck me until I had the dream about older creatures questioning this wisdom.

In this dream, those creatures were dinosaurs. I was not scared; they weren’t threatening with their question. They were fighting for their rights and trying to understand the glorious plan, and beyond.

It seemed to me a lovely coincidence that I had a visit to Washington coming up soon and had a chance to visit the National Museum of Natural History, where you can see well preserved remnants of various dinosaurs.

All of the dinosaurs went extinct long before the first human showed up. Dinos first walked on earth over 200 million years ago and dominated the earth until 66 million years ago. Their dominion on earth ended with the Cretaceous–Paleogene extinction. According to fossil records, there were more than 1000 dinosaur species. Dinosaurs had different habits of eating, as some were herbivorous (plant-eating) and others were carnivorous (meat-eating), including fish-eaters and insectivores, and omnivores (including both animals and plants in their diets). We should be thankful that we never knew many of the carnivores like T-Rex, which measured up to 12m (40ft)! It’s obvious that we could not live on earth if T-Rex were still running around. For our arrival, their departure was necessary.

There is no doubt that the human species is very valuable from various aspects, but what puts each person on the same level with another species?

One of humanity’s great merits is our collective understanding. This collective consciousness can be more fully realized through the glasses of faith in God. With the window of faith, humans not only comprehend His speech, but are better attuned to their fellow living beings – and maybe even non-living creatures. Humans are like one who is that all-inclusive and hears all other things. Hence, we can grasp proofs of the most beautiful names of the Creator from the speeches of all creatures.

The light of such understanding in humans leads to an expansion and improvement in our soul. This makes our value high, our sight universal, and our ability to achieve to perfection limitless. On the other hand, many other species are limited in many aspects by their nature, sights, and capacity of perfection. According to religious texts, though humans and other species are valued differently on earth, the divide grows larger in the hereafter. While every human being is re-created with their names, features, matter, and manner, other species return back to the soil.

When you visit nature museum next time, try to listen what the fossils of extinct species tell you about their complaint. They were created for a purpose; they have finished their job and gone. They have done a fantastic job and flourished, while leaving us many petrol reservoirs. Though countless species have gone extinct, more than 1.6 million other species are still living on earth. Death is not an end; nowadays, they are trying to reach out to us and tell us their secrets. We’re expected to become the best fruit of this universe.

This dream made me think about how the ways that Allah could teach us is not limited to what we do when we are awake. Would you ever think that ancient extinct species would also need the lights of the everlasting speech of the All-Wise and All-Powerful, as explained by why a man could be equivalent and worthy of a species of another creature by Bediuzzaman?

Another lesson is that as we live in an oil dependent-century, we are counting on reservoirs that formed millions years ago by the remnants of ancient living beings; but just as we depend on them, ancient extinct species are also counting on us and expecting us to contemplate our purpose for being here, and to show that we’re worthy of being the most glorious fruit in the universe. As the All-wise make things with infinite wisdom, he sends oil to people of this century to help in technology and he also sends further mercy in the form of knowledgeable scholars to answer our questions.

It has been known by epidemiologists that people who grew up in farms are less likely to acquire immune diseases such as asthma, allergies, inflammatory bowel disease and multiple sclerosis when compared to people living in cities. Such observations have been the roots of “hygiene hypothesis,” which essentially points out the beneficial effects of being exposed to infectious agents. Supporting this theory, a recent study at Harvard Medical School showed that exposure to symbiotic bacteria has a long lasting beneficial effect on the immune system development. “We as a species are not exposed to the same germs that we were exposed to in the past,” said the co-author Dennis Kasper, a microbiologist at Harvard Medical School in Boston. In this study, published in Science, the researchers compared germ-free mice to mice with normal bacterial flora. Germ-free mice showed significantly higher levels of invariant natural killer T (iNKT) cells in their colons and lungs. “We made the serendipitous observation that these cells were dramatically enriched in the lung and colon in mice that lacked any microbes,” said the co-author Richard Blumberg, the chief of gastroenterology at Brigham and Woman’s Hospital in Boston. Body’s own production of elevated iNKT cells correlated with higher susceptibility to inflammatory bowel disease and allergic asthma in germ-free mice. Most strikingly, the study showed that exposure to these bacteria in late age did not lower the susceptibility to these immune diseases, indicating that the bacterial exposure needs to be early in life to boost the immune system. After all, broad-spectrum antibiotics for babies may not be such a good idea.

2- Giant chickens of Jurassic Park

Original article: Xu X. et al, Nature 484, 92 (2012)

Many of us undoubtedly learned a lot about dinosaurs from the famous Sci-fi movie Jurassic Park, but who would have imagined that some gigantic feathered dinosaurs would be running along with our favorite monster T-Rex? Paleontologists have recently made an incredible discovery in Liaoning Province of China. They found a set of perfectly preserved fossils that belong to a previously unknown species of dinosaurs. These 125-million-year-old feathered giant dinosaurs represent the largest feathered animal species ever lived on earth. The adult one is predicted to be at least 9 meters (30 feet) long with a weight of 1400 kg (~3000 pounds), which is approximately 40 times bigger than the Beipiaosaurus, largest known feathered dinosaur. New gigantic feathered dinosaurs are given a Chinese-Latin name Yutyrannus huali meaning a “beautiful feathered tyrant.” Simple filament like structures as well as the relatively small sizes of feathers seem more similar to feathers from a baby chick than the plumes of an adult bird, suggesting that Yutyrannus used feathers not for flying but for body temperature insulation, perhaps under the harsh climate conditions of that age. Paleontologists are really excited to see that how much more we have learned about dinosaurs over last 15 years and they predict that many different feathered meat-eating dinosaurs lived before and they are still yet to be discovered.

3- Stardust mystery revealed

Original article: Norris B.R.M. et al, Nature 484, 220 (2012)

Heavy elements are formed in the cores of stars and are crucial in formation of celestial structures like our earth. When an intermediate-mass star dies, it triggers a cosmic sandstorm that lasts thousands of years ejecting more than half of its mass into space. Our Sun is expected to go into a similar phase in around 5 billion years. Scientists observed these sandstorms for years but it was a mystery how these particles found could leave the vicinity of the stars and find their way into interstellar space. Computer simulations hinted that these sand-like particles could not be that small, otherwise they would be evaporated by the immense heat of the dying star. Scientists using the Very Large Telescope in Chile had a chance to explore these stars in a greater detail and discovered that the size of these particles is around a micrometer. This size might seem very small to us but for these particles, it is large enough to behave like mirrors for the light rays coming out of the star instead of absorbing them. Since light also behaves like a particle, the momentum transferred by this reflection helps particles to accelerate to the speeds like 10km/second. As the lead author of the study, Barnaby Norris from University of Sydney says: “The dust grains are like lots of little sails catching the wind, or in this case, starlight.” The material that comes out of the stars is recycled during the formation of new stellar objects like our old planet.

4- Babies understand more than we think

Original article: Bergelsona, E. & Swingley, D., P.N.A.S. 109, 3252 (2012)

Most babies do not say a meaningful word until they are a year old. It was not clear whether they knew the meaning of the words prior to the speaking age. It is easy to ask the question on whether the babies understand words but it is hard to scientifically measure it. The researchers from the University of Pennsylvania devised an ingenious experiment to test the hypothesis whether the 6-9 months babies understood the common words. During the experiment babies sat on their parents’ lap in front of a computer while some images of body parts or foods were shown on the screen. The parents were given instructions through headphones about what to say to the baby about the image on the screen. Babies were monitored by an eye-tracking device to measure their attention being directed to screen. The researchers designed a control environment by pairing a body part and a food item. For instance, if a banana and some hair were shown on the screen, the researchers measured the time that the baby fixated on the banana when the parent instructed the child to look at the banana versus when the parent instructed the baby to look at the hair. 33 infants of ages 6 to 9 months and 50 toddlers of ages 10 to 20 months were recruited for this study. The study convincingly showed that the babies fixated longer on an object when they were instructed to do so. Moreover, as the age of the babies increased the period of fixation stayed pretty much constant until 14 months, but jumped dramatically afterwards. The reason behind the jump in 14 months begs further research. Now, the researchers want also to test the vocabulary of the babies and whether the babies also understand the abstract concepts.
