Whitt, Stephen. "On Our Own Two Feet." Odyssey: Adventures in Science Oct. 2009: 26-28. Print.
Walking is a strange and rare way of moving between animals. It is weird how we can even balance our big skulls. Walking on two feet started millions of years before brains got this large. Also this might be a surprise to you but really we are not related to chimpanzees. Sure we had a common ancestor but then we went our separate ways, so we are not related to them. Another interesting fact that I learned is that between humans and chimps the was a species called Afarensis, it was more chimp like than to humans. A scientist named Lovejoy made a famous theory about why we walk. That is so, we could free up our hands to carry things, work, and to bring food to their mate while they raised their child. Of coarse there are other theories such as, so we could get across a hot savanna to get to a forset, and to get across streams by swimming. Why we really started to walk, we might never know.
This is a skull of the Afarensis
As the author says,"A.Afarensis lived around three million years ago, about halfway between modern humans and chimps and our last common ancestor." The interesting part of this passage is that all of these things that have happened are pretty recent. We cannot say for sure what will happen next.
