quote:Using synchrotron microtomography, Dr. Kundrát and colleagues examined one of 12 Archaeopteryx specimens, known as ‘specimen number eight.’
“This Archaeopteryx individual is physically much closer to a modern bird than it is to a reptile,” the paleontologists said.
“Therefore, it is evolutionary distinctive and different enough to be described as a new species — Archaeopteryx albersdoerferi.”
quote:Some of the differing skeletal characteristics of Archaeopteryx albersdoerferi include the fusion of cranial bones, different pectoral girdle (chest) and wing elements, and a reinforced configuration of carpals and metacarpals (hand) bones.
These characteristics are seen more in modern flying birds and are not found in the older Archaeopteryx lithographica species, which more resembles reptiles and dinosaurs.

If evolution is shown to be false, it will be at the hands of things that are true, not made up. --percy
