Homo georgicus
H. georgicus is often classified as Homo erectus georgicus. The classical textbook definition of H. erectus included a brain size range of between 9001150 ccs. If the georgicus specimens and the Flores specimens (Homo floresiensis) are included in H. erectus, then the range of brain capacities is two-fold, from 600 ccs to 1150 ccs. Homo ergaster is also considered by some to be a subspecies of H. erectus. Size has something to do with it: both the georgicus and floriensis were much smaller than the classic erectus, which was as tall as modern man. The classification of all these species or subspecies is provisional at present, and still being debated.
