The search for human origins is a fascinating story – from the Middle Ages, when questions of the earth’s antiquity first began to arise, through to the latest genetic discoveries that show the interrelatedness of all living creatures. Central to the story is the part played by fossils – first, in establishing the age of the Earth; then, following Darwin, in the pursuit of possible ‘Missing Links’ that would establish whether or not humans and chimpanzees share a common ancestor. John Reader’s passion for this quest – palaeoanthropology – began in the 1960s when he reported for Life Magazine on Richard Leakey’s first fossil-hunting expedition to the badlands of East Turkana, in Kenya. Drawing on both historic and recent research, he tells the fascinating story of the science as it has developed from the activities of a few dedicated individuals, into the rigorous multidisciplinary work of today.

In these videos, John Reader, author of Missing Links: In Search of Human Origins talks about the treasure hunt that is the search for the missing link.

By John Reader A blaze of media attention recently greeted the claim that a newly discovered hominid species, , marked the transition between an older ape-like ancestor, such as Australopithecus afarensis, and a more recent representative of the human line, Homo erectus. As well as extensive TV, radio and front-page coverage, the fossils found by Lee Berger and his team at a site near Pretoria in South Africa featured prominently in National Geographic, with an illustration of the three species striding manfully across the page. In the middle, Au. sediba was marked with twelve points of similarity: six linking it to Au. afarensis on the left and six to H. erectus on the right. Though Berger did not explicitly describe Au. sediba as a link between the two species, the inference was clear and not discouraged. The Missing Link was in the news again.

The Hands: Made for Climbing
A digitally rendered composite hand of the "Ardi" partial skeleton. The hand structure suggests "Ardi" could climb trees, using lengthy fingers and big toes for grasping, but it could also walk on the ground in a two-legged manner.

Myth Busted: Humans Never Evolved From Chimpanzees

Although chimpanzees remain our closest living primate relatives, there is now no evidence that Homo sapiens somehow evolved from chimpanzee-like individuals, losing chimp characteristics over time. Instead, after the chimp/hominid split, the two groups appear to have gone their separate evolutionary ways, developing the unique traits seen in each today.
