Neanderthal-Homo Sapiens Hybri

al regions from an earlier dispersal of Homo erectus, or conversely from modern humans evolved in Africa only which then dispersed to replace those hominids in said regions. These two theories are known as the Continuity or Regional model and the Replacement or Out of Africa model respectively. The fossil (skeletal) and cultural (technological) evidence thus far has pointed to convincing arguments on both sides, which proponents are quick to defend. Neanderthals can be distinguished from anatomically Modern Humans by the presence of prominent brow ridges, low forehead, occipital bun, facial prognathicism, large nasal aperture, and shorter, sturdier skeletal features most notably, distinguishing them from Moderns who were taller and had longer limbs, higher foreheads, lass prominent browridges and rounder skulls. It should be noted that the cranial capacities of both were comparable, with the Neanderthals being even slightly larger. (Klein: 1989) Many proponents of a regional theory claim that such morphological differences show a continuity and depending on how they are viewed can be seen as evidence of variation within a species, not distinct species. This would mean that the Neanderthal morphology developed as an adaptation to the colder glacial climate of Europe and elsewhere. (Wolpoff:1980) From a replacement standpoint however, these differences in morphology are too distinct to be variables on a theme and in conjunction with dates provides evidence supporting that view. (Mellars and Stringer:1989) Neanderthals occupied Europe and the Middle East during a time range usually agreed upon as ranging from roughly 130 kya - 35 kya to as recent as approx. 26kya. Modern populations are seen as early as 100kya in the Middle East and around 40 kya in Europe. At some sites in the middle east, both populations lived in very close proximity to one another for what is thought to be a time range of about 40 000 years. (Akazawa et al:1998) Recent...
