Mammals shrink faster than they grow - Technology & Science An international team of scientists, including some from Canada, has discovered that mammals shrink at faster rates than they grow — a finding that sheds light on the conditions that potentially contribute to extinction. Their study, published Monday in the Proceedings of the National Academy of Sciences, shows it took about 24 million generations for a mouse-sized animal to evolve to the size of an elephant, but only 100,000 generations for very large decreases leading to dwarfism to occur. The research is unique because previous work in this area has focused on microevolution — the small changes that occur within a species.

It Takes 24 Million Generations For a Mouse To Evolve Into an Elephant Wrong. It can never happen. Just because two different species may have bits of genetic code that resemble those of another species does not mean that they "evolved" from some other "primative" or "common ancestor" species. Those similar genes that two or more different species happen to have, can be likened to some certain ingredient(s) that two or more different dishes (food) happen to share.
An artist's rendering of a Tegopelte, a foot-long arthropod that lived 500 million years ago.Marianne Collins An ancient cockroach-like creature nearly a foot long once skittered along the seafloor in what is now Canada, a new fossil find reveals. The fossil, a series of 500-million-year-old tracks, captured the movement of a large seafloor-dwelling creature with at least 25 pairs of legs. The animal was likely an arthropod called Tegopelte, a rare giant very rarely found fossilized. Arthropods are invertebrates with exoskeletons, a group that includes today's crustaceans and insects. 50-Legged Creature May Have Been Top Predator Of Ancient Seafloor
Most Beautiful Dinosaur Park July 16th, 2011 Toxido In this time most of little kids don’t know about dinosaur because they are not still alive but our 3d and historical Hollywood films give a good view on dino life and therefore kids know very well. In old age dinosaur is most biggest animals on the earth and dinosaur also have different species some dinosaur is like to eat vegetable and some dinosaur love to eat others small animals or small dinosaurs some time one big dinosaur is killed another big dinosaur but its so rare.
Evolushark Evolushark, a blue shark uniquely formed by the word "evolution", is a science mascot specifically designed to discourage conservative Christians from trying to inject creationism into public school science curriculum. By intimidating their mascot Ichthys, Evolushark symbolically warns conservative Christians that attempts to impose their sectarian beliefs on America's secular society face strong opposition. Secularism, the view that public education and other matters of civil policy should be conducted without the introduction of a religious element, is embodied in the Establishment Clause of the First Amendment. Over the past 80 years, creationists opposed to Darwin's theory of evolution have repeatedly tried to violate this clause.
How did life originate? Living things (even ancient organisms like bacteria) are enormously complex. However, all this complexity did not leap fully-formed from the primordial soup. Instead life almost certainly originated in a series of small steps, each building upon the complexity that evolved previously:

Evolution 101: How It Works
Artificial selection in the lab Artificial selection in the lab For thousands of years, humans have been influencing evolution, through changes we have caused in the environment — and through artificial selection in the domestication of plants and animals. In many cases, scientists have carefully documented evolution through artificial selection in the lab.
