Archaeopteryx, Feather Evolution and Non-Science


Once again, the Archaeopteryx has evolutionary scientists in a flap. There are eleven good fossils showing that it had feathers, but the rapid burial required to make fossils leads to some distortion. So more fossils would have been nice. Paleontologists and evolutionary ornithologists were hoping to learn about the evolution of feathers, and the purpose for which this critter evolved them on its legs. This led to some amazingly bad speculation presented as science, even using a form of the argument from silence: Since they could not find what they were looking for, they made up further stories that had no substantiation. Bad science could be drastically reduced if scientists did not insist on forcing their evolutionary presuppositions on their interpretations of data. The evidence shows creation, not evolution.

Some of the scientists were actually doing honest speculation about whether or not this bird could fly, based on their examination of the data. When it became assertions about evolution instead of presenting reasons why or why not it could fly, things became ridiculous.
Archaeopteryx, an extinct bird represented by at least eleven distinctly feathered fossils, definitely had mature-appearing flight feathers on its legs. In fact, analysis of the eleventh known specimen of Archaeopteryx reveals that, in addition to its leg feathers, its wings, tail, body, and neck were feathery—like today’s birds. Additionally, analysis of its well-preserved wing feathers supports the oft-questioned position that this feathery bird was able to achieve lift and fly. While there is nothing “transitional” about the feathers on Archaeopteryx, researchers report these “feather trousers”1 have given them insight concerning the evolution of pennaceous (quill-like) feathers.

Eighteen long leg feathers in the fossil are oriented perpendicular to the bird’s hindlimb (tibiotarsus). There is also an additional row of shorter feathers preserved near the ankle and upper part of the foot. Unlike the asymmetrical flight feathers of the wings and tail, these leg feathers are symmetrical. The feathers flying birds use to achieve lift have an asymmetrical shape—a thin stiff leading edge cutting through the air and a longer more flexible trailing edge providing a wide surface for airflow, which is adjusted as the bird tilts the feather-bearing structure.
