| Genes Reveal the Ancient Battle Between Man and Virus |  | Viruses have always been part of our evolutionary process, constantly mutating in order to defeat the immune system, at the same time triggering changes in the structure of the DNA, which eventually gave us defense mechanisms that still work today. Some types of viruses, known as retroviruses, even have the capability of inserting themselves into the DNA, leaving traces of their existence in our genes.
Such an ancient retrovir ... [read more >>] | | 22 July 2008, 10:47GMT | (c) 2008 Softpedia |
| Evolution Favors Large Species |  | With the help of data regarding the fossils of as much as 4,000 known species of mammals that lived on Earth up to 60 million years ago, Aaron Clauset of the Santa Fe Institute and Douglas Erwin of the National Museum of Natural History created one of the most accurate computer models that estimates how the body size of mammals evolved in the last 50,000 years or so. Computer model predictions indicate that mammals tend to get bigger with ... [read more >>] | | 18 July 2008, 10:43GMT | (c) 2008 Softpedia |
| Tasmanian Devils Fend Off Cancer by Breeding Early |  | Fatal facial cancer tumors have been ravaging the Tasmanian devil populations ever since the mid 1990s, killing up to one third of the total number of the world's largest surviving carnivorous marsupials in the last decade or so. The fatal devil facial tumour disease (which in Tasmanian devils is probably spread during fights), along with the venereal sarcoma (which is passed among dogs during mating), are the only known tumor disease ...

| Likely Ancestor of Modern Flatfish Found |  | The fossils of a fish that might have lived in the shallow reef waters of Europe some 50 million years ago, have been recently identified by researchers as belonging to a possible ancestor for modern flatfish. But unlike modern flatfish which have the eyes on one side of the head and which swim on their sides along the seafloor, the fossils appear to indicate that the fish had one eye on one side of the head and the other atop the skull, s ...

| How Our Brain Will Evolve in the Future |  | The brain's ability to make fast decisions in threatening situations may sometimes literally make the difference between life and death. In our more primitive past this would have translated into fast decisions destined to help us escape from the claws of a predator; the situation is analogue even today, even if the nature of the threat might have changed in time.

| No Difference between Walking and Climbing for Small Primates |  | Duke University has shown in a recent experiment that small primates use up roughly the same amount of energy while climbing as they do while walking. The new finding could reveal why the tiny human ancestors chose to live a life in the trees more than 65 million years ago. The study involved five different species of primates, working their way on vertical and horizontal treadmills.

| Neozoic, the Era of the Mammals |  | When dinosaurs went extinct, the Neozoic (New life age) started. Life evolved towards what we experience today.
1. Paleogene (65-23 Ma) was the epoch when small mammals evolved to the high diversity we know today. Many groups perished without descendants. Birds and snakes, too, diversified greatly. The clime was somehow cooler and drier. The Paleogene period was made of three epochs: Paleocene, Eocene, Oligocene.

| White People Are Less Genetically Diverse Than Black (African) People |  | Europe may be called the Old Continent, but its current population has a rather recent origin. And a new research published in the journal "Nature" shows that white European people are less genetically diverse, carrying more harmful mutations, than the black Africans.
The results point that a population "bottleneck" could have been involved in the original colonization of Europe or the evolution of the white race. P ... [read more >>] | | 21 February 2008, 03:48GMT | (c) 2008 Softpedia |
| New 582 Genes Humans Have Evolved in the Last 60,000 Years! |  | We migrated from Africa about 100,000 years ago and, since then, we have colonized the whole Earth, adapting to new environments and diets. It is clear that this accelerated an evolution in our physical traits, in the genes connected to skin color or stature, as means of adaptation to novel habitats.

| 12 Dinosaur Facts and Records |  | 1.The name "dinosaur" comes from Old Greek "deinos" ("terrible") and "saurus" ("lizard"), and was advanced by Richard Owen in 1841. The dinosaurs emerged at the end of the Triassic, about 225 million years ago, from a group of reptiles called Archosauria. Archosauria was a sister group to lizards and they gave birth both to dinosaurs and crocodiles.

| Why Don't Pregnant Women Lose Balance? |  | You may wonder how pregnant women, with those continuously growing bellies, don't lose balance, toppling over. A new Harvard research published in "Nature" has found some evolutionary tricks: slight differences from men in the lower backs and hip joints enable women to cope with pregnancy. And the adaptive pattern was spotted only in women and the females of our immediate ancestors who were bipedal (walked on two feet), but ...

| 10 Amazing Facts about Human Speech |  | 1.The speech skill is a wonder. To produce a phrase, about 100 muscles of the chest, neck, jaw, tongue and lips must collaborate. Each muscle is a bundle made of hundreds or thousands of fibers. For the coordination of these muscles much more neurons than necessary are required for contracting the muscles from an athlete's feet. Just one motor neuron can trigger movement in the 2,000 muscular fibers existent on a calf muscle. But the ... [read more >>] | | 09 November 2007, 14:56GMT | (c) 2008 Softpedia |

| The Oldest Human Ever Found: 7 Million Years Old |  | When Toumai ("Hope of Life" in the local Goran language) was found in Chad (Africa), that changed all the theories about human evolution. This ape-like human lived 7 million years ago in a forested area, sharing its habitat with other monkeys and apes and always alert to cats, crocodiles and pythons. It spent probably some time in the trees and perhaps walked upright. Anyhow, if we saw one, we would believe it is just a chimp.

| What's the Origin of Human Languages? |  | This is really ambitious: a project attempting to track down all human language to a common oldest language ever, "alive" 50,000 years ago. It is then when Homo sapiens, who had emerged at least 150,000 years before, suddenly changed behavior. Until then, Homo sapiens was not very different from the Neanderthals. Both buried their dead, employed stone tools, and had some form of communication, mostly gestural.
