A significant study further identifies the DNA of cockatoos, in which the magnificent Palm Cockatoo has been deemed close relative of the Gang-gang Cockatoo and Galah, but not the oldest common ancestor of cockatoos. The Palm Cockatoo was found to cluster on the family tree with the white cockatoos, indicating that you might not necessarily judge a bird's relationship by its colour. The results of recent work by Nicole White of Murdoch University, might help lessen the illegal trade in parrots and their eggs by establishing a DNA profiling database, which can determine if a bird was bred in captivity or smuggled from the wild. |
