Debate on Single Origin Vs. Multi-regional Origin Theories

The theory I lean towards is the multi-regional theory because with dodo trace they now use molecular depict which shows Africa was not the incur source of modern military man desoxyribonucleic acid. The molecular evidence uses mitochondrial desoxyribonucleic acid to reconstruct our heritage and ancestors relationship to apes and baboons. The evidence that swayed my decision is the multi-regional hypothesis which showed a model for the modern human stock finished and through matched transition from gay erectus to modern Homo sapiens with links among these existences through gene studies. Because mitochondrial deoxyribonucleic acid in transmittable it mickle be used to study the increase of mutations to assemble evolutionary relationships through molecular clocks. The human species holds that some or completely of the genetic variation between the contemporary human races is ascribable to genetic inheritance from either the Homo sapiens subspecies, or even other hom inid species, that were dispersed geographic completelyy passim Asia, Europe, and Australasia, prior to modern evolution of modern Homo sapiens, which dates stick out to at least 70,000 to 150,000 historic bound ago. The sources for genetic variation in modern Homo sapiens include Homo neanderthatlensis and capital of Red China spell which is a subspecies of Homo erectus.

This view contrasts with the ace origin hypothesis which states that modern Homo sapiens evolved from a superstar geographically localized ancestral hominid population whose descendants replaced all other species of hominids over the course o f tens of thousands of years without inters! ection or subspecies. The multi-regional hypothesis was originally developed from the fossil evidence but more recent work has concentrate on molecular data in which DNA is practice into annals methodicalness. Work has been done with non-recombining DNA such as mitochondrial DNA and the Y chromosome. In 2001 a team of Chinese scientists wrote all Y-chromosome samples in China were originally derived from an ancestry of African origin.
