Thrown or not thrown by Neandertals

Jennifer Viegas reports on a new study by Jill Rhodes and Steve Churchill:

"When engaged in overhead throwing activity, such as throwing a baseball, or a spear, this increases the movement arm of the muscles and gives greater strength and velocity to the throw," said Rhodes, a visiting assistant professor of anthropology at Bryn Mawr College.
She explained to Discovery News that modern athletes, like baseball pitchers and handball players, often show a characteristic backward displacement at the shoulder joint. Usually just one joint shows this, since most people have a preferred throwing arm.
The anthropologists found this telltale skeletal characteristic in the early modern European fossils, but not in the Neanderthals.

The recent bitumen hafting article by Eric Bo√ęda and colleagues also gets a mention.
