A. Feduccia's cartoon of the bug-catching phase of bird evolution
Our alliterative title is apt on two
counts: (1) Recent research on the famous Archaeopteryx fossils suggest that this animal could indeed fly and was arboreal rather than terrestrial; and (2) The paleontologists and ornithologists are still fighting (sometimes emotionally) over how Archaeopteryx fossils should be interpreted.
The scientific acrimony centers on whether this ancient bird really evolved from small theropod dinosaurs. Prevailing theory has it that these dinosaurs first evolved feathers to keep warm and then used their feathered "arms" to help capture insects, and so on, with some aimless flapping, to the attainment of true flight. A rival, officially frownedupon theory has it that birds evolved from tree-dwelling reptiles that evolved feathers to break their falls while jumping from branch to branch! [Somehow, neither theory strikes a realistic chord. Why couldn't feathers have evolved solely for the purpose of flight? Answer: because evolutionists cannot countenance purpose in nature. WRC]
One reconstruction of Archaeopteryx. There is a remarkable superficial resemblance to the living South American hoatzin. Young hoatzin even sport claws on their wings.
Anyway, the latest fusillade in the Archaeopteryx wars was fired by A. Feduccia in Science. Feduccia demonstrated that the claws of Archaeopteryx are sharp and curved like those of modern arboreal birds and quite unlike either terrestrial birds or theropod dinosaurs. In concluding his long, detailed paper, Feduccia highlights nine additional features of Archaeopteryx that make it look like a modern arboreal bird; i.e., barbed feathers, asymmetrical flight feathers, etc. V. Morell quotes Feducci as saying, "Paleontologists have tried to turn Archaeopteryx into an earthbound feathered dinosaur. But it's not. It is a bird, a perching bird. And no amount of 'paleobabble' is going to change that."

Comment. Unremarked in the three articles referenced above is a more serious anomaly that is highlighted by the many modern features of Archaeopteryx; for example, the lack of any transitional fossils between Archaeopteryx and its ancestors. Where are reptiles with
crudely feathered, but somehow useful tails?
"A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

"Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
