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)

maybe arm agility. Then over time (about 3 to 2.5 mya) the animal becomes a hunter, being able to strike a predator, protect, and gain control over resources.

According to the bone and fossil evidence that I have learned, this is my interpretation how evolution might have happened. When a species develops tools, many things can a will change. The definition of a tool is, performing or facilitating mechanical operations.(Websters Ninth New Dictionary) Take for instance a hominid that walks on all four limbs. How easy would it be for a hominid, without agile arms, to mechanically operate a tool? It would be very difficult. This type of arboreal hominid, probably lives in a tree, swings from the branches, vision is not great, and is mostly a vegetarian. After the proto human began to walk on two feet there hands became free and moveable. Now give this hominid a sharp stick or a blunt object, practice as how to properly use it, and

Not just hominids use tools. Wood-peckers, vultures and sea otters are among the other animal species that evolved by using tools to capture food, but these creatures are not as heavily dependant as we are.(Diamond 1992 pg 36) Without tools evolution might have taken much longer. Tools had a major affect on teeth, hair, behavior, and even language.(Diamond 1992 pg 12) When developing and using tools, the species takes control over the environment and makes it work for them.
