A few years ago scientists found the skeletal remains and tools of early man. The remains were found in a South African cave about 30 miles northeast of Johannesburg and brought to the United States to study by a team of scientists from around the world. The facts of the study are now coming out and the teeth from the skull and tools date back about 2 million years. Because of the teeth, they were able to determine what type of diet these early humans had. Using a range of tools from dental picks to laser devices they were able to tell precisely what they ate.
