The photo above is an old shot of Willy Shoemaker, the jockey, and Wilt Chamberlain, the basketball player. Willy is not a dwarf of any kind. He is 4'11" tall. Wilt is not a giant. He is 7'1" tall. There is no argument—they are both Homo sapiens. What if you found their bones at an anthropological dig site? If you knew nothing about humans, you might think they represented two distinct species. After all, their skulls would have different volumes, and their postcranial bones would appear quite different from each other. This is what researchers face. Variation in a species can be enormous. There are so many classifications of hominins that it boggles the mind. Here is a list of some: Homo habilis, rudolfensis, antecessor, ergaster, erectus, heidelbergensis, floresiensis, neanderthalensis, gautengensis, cepranensis, naledi, tsaichangensis, rhodensiensis, georgicus, Denisovans, and Red Deer Cave People. This is not a complete list. There are many reasons that the taxonomy (classification) of Homo is so complicated. Some species coexisted, but they also cross mated, making all of these early hominins blends of each other. Each researcher has his own idea of who begat whom, and what makes a fossil Homo. Everyone has an opinion and no one agrees with anyone else. There is no standard among scientists, and the entire naming process is getting out of hand. Anyone who finds a fossil these days is claiming to have found our oldest ancestor, the oldest Homo, or the "missing link." Just look at the situation that recently occurred in South Africa. Last year, Lee Berger proclaimed Homonaledi, a fossil found by his son, to be this ancient Homo who was already a member of our genus while Australopithecuseines like Lucy were running around. You could hear the laugh go around the paleo world when the fossils were found to be a mere 250,000 years old.
