i have the exact same opinion.i haven't read it somewhere specific i just knew it,but some time ago i heard another opinion.it claims that we had jumped to the conclusion that birds come from dinos due to lack of evidence,but recently a new evolution link for birds had be found and we have left the dino-theory behind!!!
it's an opinion from a greek biology high school teacher,that i have heard from second hand so i it's not very reliable...so i i would like to have and other opinions
thanks in advance for your replies.

The consensus seems to be that birds actually are surviving theropod dinosaurs - the evidence for this is pretty overwhelming.

Wasn't there some small feathered, tree-dwelling dinosaur that was discovered in China some time ago?!?

I figure that is some solid evidence that they are closely related. Reptiles were different from dinosaurs...

Dinosaurs were a product of atmosphere containing much oxygen.

Uh, who told you that? Seriously...


Like all organisms in evolution, they're just a product of adaptive niches. These adaptive niches probably opened up post the Permian–Triassic extinction event.

Create a terrarium rich in oxygen and reproduce reptiles and birds parthenogenetically!
And even without selecting the big ones, they will separate by themselves.

Right, I don't think any species of birds can produce parthenogenetically.
