Abstract
Homo erectus fossils can be divided into four zoogeographic zones that show different rates of endocranial expansion during the Pleistocene. When these are also grouped into three time levels, we find small increases from early to middle forms, and regularly greater increases from middle to late forms. These increases fit a regular pattern that also accomodates all archaic types, including Neandertals, as late subspecies ofH. erectus.
