2. Homo habilis
The Handy Man
Dating back to between 2.5 to 1.8 million years ago.
Fossil remains were first found in Olduvai Gorge, Tanzania in the
1960s, by Luis Leakey, Philip Tobias, and John Napier.
Stood about 3 and a half feet tall, had long arms when compared to
its legs.
It gained its place in the genus Homo because of its skull.
Large quantity of stone tools, like the Oldawan chopper or hand-axe
found around H. Habilissites.
3. Homo rudolfensis
This species was discovered in the upper Burgi Member of the
KoobiFora Formation in east Lake Turkana, Kenya, just south of the
border between Kenya and Ethiopia .
These fossil remains can confidently be dated to be between 1.88
and 1.9 million years old.
The braincase which was measured at 775 cc. this is over a 100 cc
larger than the average size of Homo habilis.
The lumpers only recognize three species in the genus Homo: Homo
habilis, Homo erectus, and Homo sapiens. The splitters, on the
other hand, recognize nine species in the same genus, one of these
being Homo rudolfensis.
4. Homo ergaster
Workman
KNM-ER 992
KNM-WT 15000
!
Lived in Kenya, from 1.49 to 1.9 million years ago
Face tucked under the brain case, foreman magnum that is displaced
forward, eyes set wide apart with a bar that spans over them, top
of face is nearly vertical, upper jaw juts forward, roots of upper
front teeth are vertically set, mouth is widely separated from nose
opening, cheeks are slender.
First hominem with a body size and shape that is more like that of
modern humans.
5. Homo erectus
Java man
Homo erectus was capable of communicating, their tools became
thicker and spears were lighter and more sophisticated.
*
Eugene Dubois discovered the remains in Java, Indonesia.
Dating back between 1.25 mya to 700 thousand years ago.
The Sangiran skull has the most complete findings with the face
vertically set, the upper jaw barely jutting out, and teeth set
vertically.
Due to a sense of autonomy, H. Erectus migrated for food and did
not have to depend on the environment.

Homo habilis: This cranium, 'KNM-ER 1813,' was discovered in Kenya
and dates to 1.9 mya.
Homo rudolfensis: KNM ER 1470, discovered in KoobiFora (Kenya) by
Bernard Ngeneo.
Homo ergaster: Confirmed the co-existence of Homo and
Australopithecines in Eastern Africa. Considered a female.
KoobiFora, Kenya 1975.
Homo Erectus: One of the more complete crania (D-2282), shown here,
was discovered in 1999 and enabled researchers to classify the
hominid as Homo erectus.
