According to archeological and physical record, tool use has had an enormous effect in the transformation of proto humans into modern humans. What stimulated tool use was the proto humans intrest in new and easier ways to do things. With the introduction of tools, body morphology changed and reproductive fitness increased. Evolution did not happened over night. It took 4.5 million years for humans to get where they are today.Scientists have concluded that about 3.5 million years ago, there was the first proto human. A proto human resembles extinct hominid populations that had some but not all the features of a modern homo sapien. Such features were prolonged moments of bipedality, change in the pelvis and the reduction of the sagittal crest. (Diamond 1992 pg 34) In order for this proto human to evolve into a human, it needed tools. Some of the tools might have been discovered by accident or by early creative geniuses? The way they discovered the tools is unknown, but the changes the tools made were to the physical morphology and the body behavior. They began to walk upright, gathered supplies, cut food, and used weapons.(Diamond 1992 pg. 40)
