Perhaps the world’s most famous early human ancestor, the 3.2-million-year-old ape “Lucy” was the first Australopithecus afarensis skeleton ever found, though her remains are only about 40 percent complete (photo of Lucy’s bones). afarensis was for about 20 years the earliest known human ancestor species (Africa map).

Johanson hypothesized almost immediately that Lucy was a female because of her small size. He was knowledgeable about fossil hominin discoveries made by other researchers, in other parts of Africa, in decades prior to the Lucy discovery. Males of Lucy’s species were probably closer to 150 cm tall (McHenry, 1991).

Scientists found four bone fragments and a tooth that detailed radiocarbon and DNA tests show are from four Homo sapiens, the oldest of which is dated to about 46,000 years ago, according to two studies published Monday in the journals Nature and Nature Ecology & Evolution.
