Bipedalism represented survival and adaptation to the environment.
Almost 2 million years ago our ancestors left the trees for the savannah.
The pebble, found some distance from any possible natural source, was in the possesion of a female Australopithecus africanus, an early hominid living between 3 and 2 million years ago.
The pebble was not a manufactured object, but it was possibly recognized it as a symbolic face, and treasured as such.
It was 1 million years later when the whole rock, not the fragments, was fashioned and used as an axe.
This tool-making then evolved over the next million years. Language is important because that implies 'culture' - the spread of knowledge; copying and informing.Palaeoanthropology, the study of our ancestors, has leapt forward in several important fields in the last few decades.Moreover, DNA analysis and molecular biology have led to extraordinary advances in our understanding of the regional biological history of modern humans.Bipedalism was a gradual process - some climbing, some walking.Bipedalism probably evolved many times throughout the evolutionary tree.This tiny piece - only 3.5 cms in height - of volcanic scoria, reddened by heat and incorporating specks of charcoal does not immediately resemble a figurine.Largely natural, it is the groove around the neck and others on the sides which have been shown to be deliberate modifications absent from other scoria found in the area.Examination under a microscope suggests this shape may have been emphasised by deliberate alteration of the natural grooves which run across the body. The Berekhat Ram sculpture, discovered in the Golan Heights, Israel, is between 250,000-280,000 years old.It may be the oldest known representation of a woman.As humans, we can breathe and speak without thinking.Apes have a balloon-like organ connected to the voice box which makes loud booming noises; humans do not.
