Unique Skull Find Rebuts Theories On Species Diversity in Early Human

This find is forcing a change in perspective in the field of paleoanthropology: human species diversity two million years ago was much smaller than presumed thus far. However, diversity within the "Homo erectus," the first global species of human, was as great as in humans today."
