The Origin of Birds any other group of animals. This was at the time in opposition to the view of anatomist Sir Richard Owen of the British Museum, who viewed "Archaeopteryx" as no different taxonomically from modern birds. Huxley's work was controversial, and this climate of uncertainty and contention about bird origins persisted well into the beginning of the 20th century. While the dinosaur-bird connection (or lack thereof) was being pursued in paleontology, the problem of the evolution of flight was under scrutiny as well. It was observed that a number of animals with moderate flying or gliding ability, such as bats, flying lizards
Archaeopteryx be black throughout, with heavier pigmentation in the distal tip. The feather studied was most probably a dorsal covert, which would have partly covered the primary feathers on the wings. The study does not mean that "Archaeopteryx" was entirely black, but suggests that it had some black colouration which included the coverts. Carney pointed out that this is consistent with what we know of modern flight characteristics, in that black melanosomes have structural properties that strengthen feathers for flight. In a 2013 study published in the "Journal of Analytical Atomic Spectrometry", new analyses of "Archaeopteryx"'s feathers revealed that the animal
