Dinosaurs And Birds

Are dinosaurs and birds really dinosaurs, they are the only one related. In recent years, this problem has brought a new life through overwhelming facts found in newly discovered fossils and fossil research discovered in the past. Two groups were formed in this question study: people who believe birds are the direct result of dinosaurs, people who feel dinosaurs and birds must have a common ancestor. The judgment of which opinion is correct is based on an actual viewpoint.

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.

Birds have evolved from dinosaurs, but does this mean that dinosaurs are still alive by quoting some common proverbs? Or should we classify dinosaurs and birds in the same group and treat birds as the only representative of life to make the problem more practical? Paleontologist R. T. Bakker and P. M. They proposed this course when Galton proposed a new vertebrate dinosaur to accommodate birds and dinosaurs. We have not organized formal questions in taxonomy based on biological assertions on structure and physiology. There are taxonomists who join two groups (eg dinosaurs and birds), another group of other groups (such as dinosaurs and other reptiles), when there is no descendant from the two groups. Formerly, it must be unified with formal classification. In this so-called branching (or branching) classification system, dinosaurs can not become reptiles unless the bird does.
