Homo erectus- cranial capacity is significantly larger than homo habilis, and because it’s bigger, you expect them to do more with that space. With erectus we find associated with them a new tool called acheulian and these are an improvement of oldowon tools. These tools start out with a cobble stone that is worked into a hand axe. These tools are not really spear points but are tools for hacking away are carcasses. These tools show us that we find them wherever we find homo erectus sites or fossils. We’ve found them in Africa, Europe, china, etc. The same tool type spread over the world at the same time period. Indicating that the idea of making these tools were carried in the mind and passed on place to place across the old world. This of course shows some kind of complex communication skills. We can see from the inside of the homo erectus brain that the part of speech associated is not as complex as modern homo sapiens. We also see other indications of greater learning for example, engraving on bones, acheulian stones could be used for wood or bone. Besides stone tools, we see other types of tools that wouldn’t of been preserved, wood tools and bone tools. Some sites indicated living spaces for a long time, such as the fire sites. What we have with homo erectus is a highly successful hominid form. They were very successful in taking homo erectus culture and spreading it around the old world. The culture doesn’t change or their physical appearance…a highly successful form adapted to a scavenging environment, a perfect example of punctuated equilibrium. Between 600,000 ya and 200,000 ya, what we have is a challenge in human evolution. We have a new fossil form and the question is should this new fossil form be lumped inot homo sapiens or are they different enough to be in a different species? The fossil record in human evolution shows a gradual transformation, a perfect example of more transitional forms. Homo heidelbergensis fossils are found in Africa, Europe, and also in Asia. They show a perfect transition between one species inot the next and representing the line that splits the two species. After that, there are the homo sapiens. The oldest homo sapiens come from Africa, where they not only physical but something
