for something different, I thought I'd post this from facebook from Nautilus Magazine: Unlike an old-fashioned family tree, this tree of all birds shows representatives of different avian families living today ringing the outside of a circle. The point in the middle of the circle stands for the common ancestor of all birds, and the connections between the individual threads branching off from that point chart the evolutionary connections between thousands of bird species. The shorter the branches connecting one species to another, the more closely related those species are. For example, ostriches and similar birds are more distantly related to other living bird species. The threads are colored based on how many published studies contributed information to our understanding of the relationship—brightest green is 10 or more, gray is 0.
