The Debate Over Birds and Feathered Dinosaurs

Controversy about dinosaurs of birds and feathers Because dinosaurs live millions of years ago, we depend entirely on the fossils they left. As paleontologists say everyone, fossil hunting is difficult. There is no certainty, no guarantee. Some luck is as valuable as scientific knowledge. From time to time, people will find an attempt to change the actual lifestyle of dinosaurs or how they are thought before.

A: Many scientists believe that birds are dinosaurs. Of course, birds are descendants of carnivorous dinosaurs, and the earliest birds look the same - except for the impression of feathers - like dinosaurs with snack meat. This is a semantic problem, so the birds live in dinosaurs or closest relatives. (Don Lessem) Q: Dinosaurs are a little nomadic, so scientists have heard that dinosaurs are thought to be dying from sickness. They move to new areas and are exposed to bacteria that their immune system can not fight. is it true? He also hinted that the mainland is not completely separated in this way.

Most paleontologists now consider the birds the closest relatives of dinosaurs. In fact, they say the birds are dinosaurs - colorful, very diverse, cute little feather dinosaurs. Jurassic Forest's beast legs live in the garden in the gold finch backyard, the tropical Animal Cat, and the ostrich across the African savanna. To understand her dinosaur bones, Schweitzer looked at the most primitive two birds, ostriches and crickets In the summer of 2004 she asked an ostrich breeder about female bones . A few months later, farmers called. "Do you still need a woman with an ostrich?" Dead birds were in the farmhouse's backhoe for several days at high temperatures in North Carolina. Schweitzer and the two colleagues gathered legs from the fragrant body and put it back to Raleigh.

Because feathers are often associated with birds, feather dinosaurs are often advertised as links that do not exist between birds and dinosaurs. However, the multiple skeleton functions shared by the two groups represent a more important link between paleontologists. In addition, it is becoming increasingly evident that the relationship between birds and dinosaurs and the evolution of flight are more complex subjects than previously realized. For example, some people thought that birds evolved from linearly evolved dinosaurs, but some scientists, especially Gregory S. Paul, believe that dinosaurs like Dragon Blood Dragon evolved from birds, probably with feathers I lost the power of flight while maintaining. In a way similar to modern ostriches and other flat chest birds
