Homo sapiens, are we sure it is our progenitor? Homo sapiens from the Latin “wise man” is the definition of modern man taxonomic. It belongs to the genus Homo, of which he is the only living species in the family of hominids and the order of primates. The period from the Middle Paleolithic, about 200,000 years ago, at the time today, sees the appearance in East Africa and the diversification of the species Homo sapiens.
According to prevailing theories, from the African continent, about 65 to 75,000 years ago, in close connection with a strong reduction event of the global population, which is still being finalized, part of the species it began a migration path through a middle eastern corridor brought to colonize the entire planet. The African origin of the species, the Ethiopian discoveries in the volcanic tuffs, approximately 200,000 years of the Omo River valley ago by H. Erectus, to date, H. sapiens has spread across the surface of the land on with a total population It passed in March 2012, the 7.0 billion individuals. The single origin Hypothesis proposes that modern humans evolved in Africa and then migrated outside are replacing those hominids who were in other parts of the world. On it, there is vast paleoanthropological evidence given by several thousand fossils, Archaeological, linguistic, climatological, genetic.
The molecular data conducted by non-recombinant markers, such as mitochondrial DNA, support this hypothesis.
The pro-geographic analysis has in fact shown that the peopling of the continents by modern man proceeded in successive waves from the African continent. The paleo-anthropological data show that in principle would emerge a population of southern Africa, isolated from the rest of the population, in an age of between 100 and 200 000 years ago, made up of individuals rather puny compared to the prevalent types of Homo heidelbergensis and Homo neanderthalensis. The original people of today’s humanity were made from a Khoisan population ancestral from which derived the current ethnic Khoisan.
