The Origin of Anatomically Modern Homo sapiens and the Fate of Neanderthals

The specific they end up of arguments was about their physical appearance in which each of them was distinguish by a unique set of anatomical features . The Neanderthals are characterized with a large , long , low cranial vault with a well-developed double-arched brow ridge

a massive facial skeleton with a very projecting mid-face , backward sloping cheeks , and large nasal aperture , with large nasal sinuses

an oddly shaped occipital region of the skull with a bulge or bun

molars with enlarged pulp chambers , and large , often very heavily worn incisors

a mandible

lacking a chin and possessing a large gap behind the last molar . While the Homo sapiens were a cranial vault with a vertical forehead , rounded occipital and reduced brow ridge , a reduced facial skeleton lacking a projecting mid-face a lower jaw sporting a chin , a more modern , less robustly built skeleton . These two s gave much idea on how they differ each other

Are we genetically different from our Homo sapiens ancestors who lived 10-20 ,000 years ago ? The answer is almost certainly yes . In fact , it is very likely that the rate of evolutionary change for our species has continuously accelerated since the end of the last ice age , roughly 10 ,000 years ago . The evidence for a biocultural transition between the Neanderthals and early modern human populations they creatively construct social and cultural identities that transcend actual biological kinship (Wobst 1977 . The best-documented early examples of symbolic artifacts are bone , ivory and stone beads from Aurignacian

This is mostly due to the fact that our human population has deliberately grown and moved into new kinds of environments , including cities . This has exerted strong selection for individuals who were fortunate to have immune systems that allowed them to survive . We have been exposed to new kinds of environmental pollution...
