Latest study: Scientists say no evidence exists that therapod dinosaurs evolved into birds

or books, including The Age of Birds, which Harvard University Press published in 1980 and The Origin and Evolution of Birds, published by Yale University Press in 1996.

Among other discoveries, Feduccia found by a careful examination that Archaeopteryx, the earliest known bird and one of the world's most famous fossils, could fly. Previously, many scientists thought the animal to be an Earth-bound dinosaur.

He determined its flying ability by observing that the fossil's feathers had leading edges significantly shorter than their trailing edges, which is characteristic of all modern flying birds. The edges of feather of birds incapable of flight, such as ostriches, are symmetrical.
