Despite the increasingly clear picture of the evolution of birds from theropod dinosaurs that has emerged, a few scientists are still unconvinced. No alternative hypothesis has been offered to ...
Over time, some of those dinosaurs sprouted feathers and took to the skies—and while their reptilian cousins died off, those ...
The fossil of a tiny bird that lived 62 million years ago confirms that birds evolved very rapidly after the asteroid strike that wiped out the dinosaurs. The sparrow-sized tree-dweller lived ...
New fossil evidence has pushed back a key step in the evolution of bird flight by millions of years. Skeletal changes that helped birds take to the air happened 120 million years ago, during the ...
"My lab has been chipping away at this problem of bird evolution for longer than I want to think about," said Edward Braun, Ph.D., the senior author of the paper published in the Proceedings of ...
We now have a well resolved and well sampled molecular framework, including more than 700 passerine bird species. This is ideal for advancing the understanding of island biogeography, island evolution ...
You can map all of those things out and that can tell you the narrative of how evolution took a dinosaur and turned it into a bird.” “We can also calibrate that tree to time,” explains the ...
From the Galapagos Islands to New Zealand, species of birds that exist today model characteristics of their ancestors that provide clues to the environmental forces that shaped their evolution.
When one misguided bird found himself in the same situation, he didn’t wallow in his own self pity; he created his own entirely new species. Over the past 36 years, scientists have been closely ...
Birds evolved from small feathered dinosaurs during the Jurassic Period. The Navaornis discovery filled in a gap of 70 million years in the understanding of the evolution of avian neuroanatomy ...
Studying Bird’s style, she’s instantly recognizable on the court for her long, tied-back brown hair, which has been a signature of the player since she was a teen. The evolution of Bird’s ...
