Mrs. Charles Darwin's Advice For Walking Upright

Millions of years ago, our ancestors, who were adapted to living in trees, started to experiment with walking upright. These chance experiments turned out to be a useful skill, and over time we humans evolved bodies built for upright walking. From our neck to our feet, this brought many changes to our skeletal structure. We also evolved hands better adapted for fine motor skills, and big brains that ultimately helped us develop language. The lovely Emma Darwin, wife of Charles, has graciously volunteered to demonstrate the differences between humans and chimps. Just click on her body parts for more.
