To considering the hypothesis of the extinction of the NeanderthalsĪs an integral part of the general extinction event of the Quaternary This small interweaving is not an obstacle (2013), who have reviewed all the studies carried out to date onĮuropean ancient DNA, from the Middle Palaeolithic to the beginning of the protohistoric The role of Neanderthals in the ancestry of EuropeansĪl. In this case, however, there is evidence of a minimalĭegree of cross-linking between Neanderthals and sapiens, as suggested by both morphology and genomics (Bayle et al. Independent evolutions and separate species, such as the so-called Neanderthal man ( H. Is based on the reproductive isolation of different populations of H. It is, consequently, a monogenist model (single origin). erectus, without crossing with them to colonize the Of that continent and went on to replace all populations that descended from H. Originated in Africa, where they first evolved and then, already converted into Or ‘Noah's Ark’ model, better known as ‘Out of Africa’.
The most accepted model at present is, however, the single origin This allows us to understand that diversity is what provided the real substrateįor the set of evolutionary tests that finally, by selection, made some populations Variation in modern humans would be an ancient phenomenon based simply on Regional populations, is responsible for the ecotypes (also known as ‘races’) Geographically separated populations in such a way that it prevented speciationįrom the different populations after dispersion. One is that a gene flow must have occurred between This is,Ĭonsequently, a polygenic model (many origins). Left Africa about two million years ago and slowly evolved into H. Would not have appeared in a specific area, but rather wherever H. To this model, we evolved as a species interconnected with H. Known as the multiregional hypothesis or regional continuity model. One model of the origin of our species is Technical systems were created, their modification seems to have overcomeĮcological constraints (see e.g., Kissel and Fuentes 2018). Although human adaptations have an ecological origin, once Those who didĪdapt were transformed within the framework of natural selection until theyĬonsolidated by establishing a relationship with the environment usingĮxosomatic capabilities such as the production of tools and the generation andĬontrol of fire. Them did not manage to adapt and they were left by the wayside. There were acquired capacities that shaped a peculiar group of genera. Own genus emerged, more than two million years ago. The initial stage comprised of Ardipithecus, To unique and diversified primates were configured (Cela-Conde and Ayala 2003). Seven million years ago, the characteristics that would over time give rise
