Homo Erectus Footprint

The footprint pictured was made 1.5 million years ago in Kenya, likely by our ancestor Homo erectus. These footprints represent upright walking. Homo erectus was a great traveler - fossils have been found from Africa to China. They are thought to have used complex tools and lived in hunter-gatherer bands. These footprints are an amazing symbol of our past - newly upright humans, with their growing, adrenaline-soaked brains, always moving to survive and banding together in an unforgiving world.
