I don’t believe theres a straight answer to this question, but there have been many noted similarities between birds and dinosaurs so it is likely that modern day birds may have evolved from small tree-dwelling dinosaurs.

It probably depends to a certain extent on what kind of bird. In the long-run, they evolved from single-celled organisms.

I am pretty sure it is an uncontroversial fact within paleontology that birds evolved from dinosaurs. Actually, many paleontologists would correct me….saying that birds are dinosaurs.

Wabarr is entirely correct.

Intentional misspelling. :)

In the spirit of presenting diverse viewpoints, I will say that there is substantial evidence that the genetic information within species does not vary except for rare, non-beneficial mutations, and some information may be “turned off” in dormant genes, and can be quickly activated to help a species adapt to a changing environment. This type of evolution is very different from the theory (remember, it is a theory) of evolution which says that all species evolved from a single ancestor. I believe that it is just as scientifically valid to believe that birds were always birds, varying within the limits of their original genetic information, or boundaries.

There is a marvellous BBC series by David Attenborough called The Life of Birds, it covers evolution. Highly recommended.
