There’s no accounting for taste—a truism that extends even to the earliest humans. By 3.5 million years ago, some early hominins in the Central African nation of Chad had already developed their own distinct tastes—literally. Three members of the genus Australopithecus—close cousins of the famed Lucy—had a yen for grass and sedges, according to a new study published online today in the Proceedings of the National Academy of Sciences. The shift suggests that hominins adapted their diet to living in more open terrain, as our ancestors did at some point, earlier than thought.
