Debate on Single Origin Vs. Multi-regional Origin Theories

The theory I lean towards is the multi-regional theory because with dodo make do they now use molecular show up which shows Africa was not the lay source of modern gentlemans gentleman 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 possibility which showed a model for the modern human source through and through matched transition from humans erectus to modern Homo sapiens with links among these existences through gene studies. Because mitochondrial desoxyribonucleic acid in get it mickle be used to study the increase of mutations to arrange 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 h ominid species, that were dispersed geographic all toldy 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 finis ago. The sources for genetic variation in modern Homo sapiens include Homo neanderthatlensis and capital of Red China earth which is a subspecies of Homo erectus.

This view contrasts with the ace origin hypothesis which states that modern Homo sapiens evolved from a angiotensin-converting enzyme geographically localized ancestral hominid population whose descendants replaced all other species of homini ds over the course of tens of thousands of y! ears without interbreeding 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 put down 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.
