Today, scientists have confirmed that birds evolved from dinosaurs that were known for their sharp and pointed teeth. Until now, there has been no definite explanation of the significant evolutionary change in birds. In the ongoing study, researchers analyzed the genes of modern birds that are ...
Using recent phylogenetic statistical methods, they find that in most clades of dinosaurs there is a strong signal of an early burst'' in body-size evolution, a predicted pattern of adaptive radiation in which rapid trait evolution happens early in a group's history and then slows down. They...
We cautioned that many media ‘proofs’ of evolution are later refuted with barely a whimper in the media. Recent research has proved the point:‘New research shows that birds lack the embryonic thumb that dinosaurs had, suggesting that it is “almost impossible” for the species to be ...

Over many years, it has become accepted among paleontologists that birds evolved from a group of dinosaurs called theropods from the EarlyCretaceousperiod of Earth’s history, around 120-130 million years ago. Recent discoveries of feathered dinosaurs from the older Middle-Late Jurassic period have ...
Bird Clip Art Bird Evolution and Taxonomy Birds belong to the scientific class Aves, which includes over 10,000 species living today. All modern birds evolved from feathered theropod dinosaurs during the Jurassic period. They are the sole surviving dinosaur lineage, adapted for flight and found ...
