The species Au. Australopithecus africanus reconstruction, San Diego Museum of Man. Public Event: Religious Perspectives on the Science of Human Origins (video). The species was formally named in 1978 following a wave of fossil discoveries at Hadar, Ethiopia, and Laetoli, Tanzania. 85 and 2. Thus, the genus Homo either split off from the genus Australopithecus at an earlier date (the latest common ancestor being either A. Fossil evidence shows that male Au. garhi, and A. 5 million years ago. 95 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. Below are some of the still unanswered questions about Au. deyiremeda (proposed), A. africanus was once considered to be ancestral to the genus Homo (in particular Homo erectus ). For some hominid species of this time, such as A. This meant Au. Your browser does not support the audio element. Similar to chimpanzees, Au. afarensis existed through a period of environmental fluctuation yet showed no adaptations to the changing environment—why. A. According to the Chimpanzee Genome Project, the human ( Ardipithecus, Australopithecus and Homo ) and chimpanzee ( Pan troglodytes and Pan paniscus ) lineages diverged from a common ancestor about five to six million years ago, assuming a constant rate of evolution. Australopithecus anamensis, A. sediba. Was it because they were able to migrate to where their usual food sources were located. afarensis children grew rapidly after birth and reached adulthood earlier than modern humans.
From paleontological and archaeological evidence, the Australopithecus genus apparently evolved in eastern Africa around 4 million years ago before spreading throughout the continent and eventually becoming extinct somewhat after two million years ago. africanus are among the most famous of the extinct hominins. robustus and A. afarensis individuals had canine teeth comparable in size to those of females. afarensis that may be answered with future discoveries. 85 and 2. boisei, some debate exists whether they constitute members of the same genus. Paleoanthropologists are constantly in the field, excavating new areas, using groundbreaking technology, and continually filling in some of the gaps about our understanding of human evolution. Australopithecus species played a significant part in human evolution, the genus Homo being derived from Australopithecus at some time after three million years ago. afarensis or an even earlier form, possibly Kenyanthropus ), or both developed from a yet possibly unknown common ancestor independently. 95 million years ago in Eastern Africa (Ethiopia, Kenya, Tanzania), this species survived for more than 900,000 years, which is over four times as long as our own species has been around. afarensis, and A. During that time, a number of australopithecine species emerged, including Australopithecus afarensis, A. afarensis had a shorter period of growing up than modern humans have today, leaving them less time for parental guidance and socialization during childhood. They also had small canine teeth like all other early humans, and a body that stood on two legs and regularly walked upright. africanus, A. Found between 3. Map of the fossil sites of the early australopithecines in Africa. bahrelghazali, A. However, if these species do constitute their own genus, they may be given their own name, Paranthropus. When Lived: Between about 3. anamensis, A. The earliest evidence of fundamentally bipedal hominids can be observed at the site of Laetoli in Tanzania. Their adaptations for living both in the trees and on the ground helped them survive for almost a million years as climate and environments changed. Gracile australopiths shared several traits with modern apes and humans, and were widespread throughout Eastern and Northern Africa around 3.
