Evolution: How birds spread around the globeEvolutiondoi:10.1038/528311bNature ResearchNature
They were too big, too slow, too heavy and too old to make it to modern times. But many scientists don't see it that way at all. Instead of becoming obsolete, dinosaurs evolved into birds, which are extremely sophisticated. Not only did they become a type of animal that still exists ...
In this example, you can see evolution at work. A random DNA mutation created an E. coli cell that is unique. The cell is unaffected by the antibiotic that kills all of its neighbors. This unique cell, in the environment of that petri dish, is able to survive. E. coli are about as...
BEIJING, Aug. 2 (Xinhua) -- A team of Chinese paleontologists has made a significant discovery by identifying remnants of a vegetable diet in the stomach contents of a 120-million-year-old fossilized bird found in northeastern China. The findings, published recently in the journal Nature Communi...

In the past two decades, Brazil has yielded several Triassic fossils that are more than 200 million years old. Guillermo Rougier, a palaeontologist at the University of Louisville in Kentucky, describes them as “incredible discoveries” that are right on the cusp between mammals and their ...

South American night monkeys, for instance, can no longer see in colour, while Old World monkeys and apes can detect the full range. New World monkeys and some lemurs are even ‘polymorphic trichromats’, meaning the ability to see in full colour is split within the species: some females ...
“Because dinosaur mandibles are actually built so much like living reptiles, we can use the anatomy of living reptiles to inform how we construct our mandible models,” said Fortner. “In turn, the discoveries we make about T. rex’s mandible can provide more clarity on the diversity of ...
The role for which a dog was bred—say retrieving birds—is reflected in their brain structure, according to a study of 33 breeds.
