Ardipithecus 4.4my Tim White Afar White's 1993 Earliest known hominid. Still awaiting White's full
description; preliminary reports hint that
ramidus (Ethiopia) afar locomotion was a unique form of bipedalism not
collection seen in any other hominids.
Jaw and long bone fragments suggest that that it
Australopithecus 4.2my to Meave Leakey Turkana Turkana 1996 was fully bipedal but with strong hand grip for
anamensis 3.9my (Northern specimens
Kenya) climbing, and more apelike jaws and teeth than
Australopithecus 3.8my to Don Johanson Afar Lucy, First 1974 The "Lucy" species found in Ethiopia, also said to
afarensis 3.0my Tim White (Ethiopia) Family, have made the Laetoli footprints. Some dissidents
Laetoli Laetoli say there's too much variation between the small
(Tanzania Lucy and the larger specimens, that there are
really two or more species in the Hadar collection,
) and that the more Homo-like form made the Laetoli
Kenyapithecus 3.5my Meave Leakey Turkana Meave's 2000 A recent addition to the hominid tree, platyops'
("flat face" ) has a small brain but its face is similar
platyops Turkana to that of 1470, leading Meave Leakey to place
finds them both in a new genus Kenyapithecus.
Coexisting with afarensis and perhaps more
humanlike, this could challenge afarensis' status
as a human ancestor
Australopithecus 2.9my to Raymond Dart S Africa Taung 1924 The Taung child's species, found in Southern
africanus 2.4my Robert Broom child, Mrs. Africa, recently revealed to have long arms and
Lee Berger Ples, short legs and said by some to have spent much
Littlefoot time in trees.

boisei boisei 1.4my Mary Leakey (Tanzania ("Zinj") Africa. Are they related, or a case of parallel
evolution? Specimens of female boisei and

not have a sagittal crest.
Unique facial morphology and dentition, but large
Homo habilis Homo 1.9my Richard Leakey Olduvai Turkana 1972 brain (775cc). Some call it an australopithecine.
