In the beginning: from reptilian creature to feathered friend, how a bird became a bird

Article Abstract:

Proto-avarian fossils found in Bavaria in the 1860s are major evidence that birds evolved from reptiles. Called the Archaeopteryx, the crow-like fossil remains had more reptilian traits than bird. The Bavarian fossils were a lucky find because fossils of fragile bird skeletons are extremely rare.
