what makes humans, human focusing on bipedalism and tool use

Finish a short paper on what makes humans, human. I focused on two things, bipedalism and tool use. It has to be about 800 words, double spaced. I have included pieces from the textbook as that was the only source we were really supposed to use. Inclusion of on the sites mentioned would be great. The citation are very casual for example (Images of the past, #) I have included what I have written so far. Thank you
