After Prof. Raymond Dart described it and named the species Australopithecus africanus (meaning southern ape of Africa), it took more than 20 years for the scientific community to widely accept Australopithecus as a member of the human family tree. In Evolution’s Bite, noted paleoanthropologist Peter Ungar brings together for the first time cutting-edge advances in understanding human evolution with new approaches to uncovering dietary clues from fossil teeth. From 1972 to 1977, the International Afar Research Expedition—led by anthropologists Maurice Taieb, Donald Johanson, and Yves Coppens—unearthed several hundreds of hominin specimens in Hadar, Ethiopia, the most significant being the exceedingly we… afraensis. A. afarensis appears to have walked with a similar gait to modern humans. The first Australopithecus described was the Taung Child, discovered by Raymond Dart, and described in 1925. Gracile australopithecines shared several traits with modern apes and humans and were widespread throughout Eastern and Southern Africa as early as 4 to as late as 1.2 million years ago. Opinion 1941 Australopithecus afarensis Johanson, 1978 (Mammalia, Primates): specific name conserved.Bulletin of Zoological Nomenclature 56, 223-224 (1999) afarensis’s remains appear in the fossil record between around 3.9 … Australopithecus literally means 'southern ape.'.

Au. The most celebrated Australopithecus, Lucy, discovered in 1974, was a member of this species. “Lucy and her kind provide important evidence about early hominin behavior. This species demonstrates a trend in human evolution: the reduction of the dentition and jaw in size. Australopithecus afarensis and africanus, and the other species above, are known as gracile australopithecines, because of their relatively lighter build, especially in the skull and teeth.

It lived between 3.9 and 2.9 million years ago. The names Praeanthropus africanus and Praeanthropus afarensis have been suggested as Investigating possible selective pressures underlying these changes is key to understanding the patterns of selection shaping the origins and early evolution of the Australopithecus-human clade. Gracile australopithecines shared several traits with modern apes and humans and were widespread throughout Eastern and Southern Africa as early as 4 to as late as 1.2 million years ago. Australopithecus afarensis is one of the longest-lived and best-known early human species—paleoanthropologists have uncovered remains from more than 300 individuals! The average weight of Australopithecus has ranged from 30-60 kg. N2 - Ferguson (1989) has recently argued that the variability seen in the fossils assigned to A. afarensis is far more than expected for a single hominid species, and therefore proposes they represent multiple taxa. This generously illustrated book tells the story of the human family, showing how our species' physical traits and behaviors evolved over millions of years as our ancestors adapted to dramatic environmental changes.
