Birds.

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...

are closely releted to dinosaurs.not birds.

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.

birds parthenogenetically?

birds parthenogenetically?

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