Where did we come from? Humans continue to search for the answer to this fundamental question. Over the years, we've turned to both religion and science to explain where our species came from. Innovators of their time, Charles Darwin and Alfred Russel Wallace, used science to explain where humans came from, posing the theory of evolution. Then, paleoanthropologists Mary and Louis Leakey explored the fossil record to see if they could piece together the story of humans. Evolutionary science and archaeology continue today. Use these materials in your classroom to teach your students about the origins of the homo sapien.
