sciencehabit writes: Four hominin individuals who died when they fell into a “death trap” in a cave about 2 million years ago at Malapa, South Africa, may help shed light on human evolution. The fossils, which belong to a species known as Australopithecus sediba may even be an ancestor of our own genus. The trove of well-preserved bones includes clavicles, shoulder blades, and ribs as well as a complete skull, hand, foot, and two pelvises. The individuals had a small brain the size of an ape's, and it had long arms and a primitive thorax and heel like an ape. But the fossils also show some surprisingly modern traits usually found only in members of our own genus, like elongated pelvises, smaller teeth, short fingers, and an elongated thumb.
