Scientists have found new evidence that Homo sapiens, or humans, have been around longer than we thought. Bones found at a site called Jebel Irhoud in Morocco are 300,000 years old. That is about 100,000 years older than any other known remains of our species. They were discovered far from where the oldest fossils had been found before in Ethiopia. Scientists decided that skulls, limb bones and teeth they found represent at least five individuals. They show people from an early stage of our species' development. They are a mix of modern and more ancient, or simpler, humans.
