Lucy Catalog no. AL 288-1 Common name Lucy Species Australopithecus afarensis Age 3.2 million years Place discovered Afar Depression, Ethiopia Date discovered November 24, 1974 ; 50 years ago (1974-11-24) Discovered by Donald Johanson Maurice Taieb Yves Coppens Tom Gray AL 288-1, commonly known as Lucy or Dinkʼinesh, is a collection of several hundred pieces of fossilized bone comprising 40 ...
Lucy measured perhaps 105 cm (3 ft 5 in) in height and 25–37 kg (55–82 lb), but she was rather small for her species. In contrast, a presumed male was estimated at 165 cm (5 ft 5 in) and 45 kg (99 lb). A perceived difference in male and female size may simply be sampling bias.
Lucy’s discovery transformed our understanding of human origins. Don Johanson, who unearthed the Australopithecus afarensis remains in 1974, recalls the moment he found the iconic fossil.
The Mitochondrial Eve can change, when a mother-daughter line comes to an end. It follows from the definition of Mitochondrial Eve that she had at least two daughters who both have unbroken female lineages that have survived to the present day. In every generation mitochondrial lineages end – when a woman with unique mtDNA dies with no daughters.
Lucy, a 40%-complete skeleton of a female A. afarensis, discovered 1974 in Hadar, Ethiopia; Selam, remains of a three-year-old A. afarensis female, discovered in Dikika, Ethiopia; MRD-VP-1/1, first skull of A. anamensis discovered in 2016 in Afar, Ethiopia. STS 5 (Mrs. Ples), the most complete skull of an A. africanus ever found in South Africa
A bipedal hominin, Lucy stood about three and a half feet tall; her bipedalism supported Raymond Dart's theory that australopithecines walked upright. The whole team including Johanson concluded from Lucy's rib that she ate a plant-based diet and from her curved finger bones that she was probably still at home in trees.
Homo erectus is the most long-lived species of Homo, having survived for almost two million years. By contrast, Homo sapiens emerged about a third of a million years ago. Regarding many archaic humans , there is no definite consensus as to whether they should be classified as subspecies of H. erectus or H. sapiens or as separate species.
The main similarity is that the Orrorin femur is morphologically closer to that of Homo sapiens than is Lucy's; there is, however, some debate over this point. [13] This debate is largely centered around the fact that Lucy was female and the Orrorin femur it has been compared to belonged to a male. [11]
