EVOLUTION OF BIRD

[siriraks arrathrakorn <arrathrakorn@yahoo.com>]

After I have read some papers. I see that many fossils have feather
and may be origin of bird. But they are living in difference time and
difference place.

So, may be.
Archaeopteryx is may not the bird origin. But they are much more
flying organism in the past and only some of them advance than other.
But it not make them derived to bird. In the past may have feather
evolution more than one time. And only some of them led to bird.


I am not paleontologist. So, is it wrong.
