Sorry, been traveling here and there lately so don't really have time to post blog updates. Found this interesting article on EurekAlert!
A new study suggests that humans share a common ancestor with orangutans, not chimpanzees according to shared physical characteristics.
Comparing physical characteristics instead of DNA, researchers Jeffrey H. Schwartz and John Grehan found that humans shared 28 unique physical characteristics with orangutans, share only two features with chimpanzees and seven with gorillas. Humans share seven characteristics with all three apes (chimpanzees, gorillas, and orangutans). Gorillas and chimpanzees shared 11 unique characteristics.
Schwartz and Grehan proposed to have a new "grouping" or classification for humans, orangutans and last common ancestor call "dental hominoids" because they all share similar thick-enameled dental.
