Whats the difference when we walk and when Chimps Walk? well according to Stephen Whitt, "As Chimps walk on all fours, their spines angle up slightly, but are nowhere near straight up and down." This means that the spine is connected to the head and the hole which is called the foreman magnum connects the spine to head. The chimps walk on fours so it will be horizontal compared to us, our spines are directly underneath our head and connect underneath. The other reason is our head and how we balance it, unlike the chimp we don't have snouts, we have straight end where our nose goes. According to C.Owen Lovejoy we started to walk so we can carry food and give food to others. Others thought that depended on behavior too much and said that we started to walk bipedally so we could cross rivers and lakes.
So when someone asks you how and where did we come from don't say "Monkeys".
