Africa: Human Evolution
The evidence of these species were also found in Lake
Turkana in Kenya in the form of the famous "KNM-ER 1470" skull
which is 1.88 millions years old.
As the evolutionary cycle continues, 1.6 million years
later, Homo habilis gave way to Homo erectus. With a larger and
more complex brain and a more erect and easier walking posture,
these creatures were the more advanced of the two, and were mostly
likely the ones who learned to use fire and the more sophisticated
tools such as hand-axes.
The earliest examples of these species and their tools
came from ancient lakeside sites in eastern Africa. Such stone-age
tools were also found in other areas in the continent, usually near
water, seldom in rainforests where there was little food.
An excellent example of Homo erectus was found in a
swamp, near the west shore of present-day Lake Turkana in Kenya. A
skeleton of a young boy was found; less than twelve years old, his
body was entombed in mud about 1.6 million years ago.
This skeleton was the most complete specimen of an
ancestral hominid ever found. At an early age, Homo erectus began
spreading to Europe and Asia, thus setting the stage for world
evolution. 1 2 3
