King Jordan The Columbian Exchange as a source of adaptive introgression in human populations 2016 8 .pdf application/pdf 6271 679 50 The Columbian Exchange as a source of adaptive introgression in human populations for its role in the creation of novel human genomes that have been shaped by rapid adaptive evolution. Keywords: Columbian exchange, Human evolution, Adaptive evolution, Natural selection, Selective sweep, Genetic From a population genomic perspective, the Columbian Exchange can be considered to have facilitated genetic admixture among three human population groups – population mixing during the Columbian Exchange generated novel human genome sequences with combinations of haplotypes that had never previously co-existed American genome sequences for adaptive human evolution, fitness and health. If genetic admixture between previously isolated populations is extensive, it can provide introgressed haplotypes at intermediate to high frequencies to the resulting can be considered to provide an opportunity for socalled 'soft' selective sweeps, which are defined as causing rapid molecular evolution via the simultaneous increase in frequency of multiple adaptive alleles in the ./cache/work_3ztz4ncxbfbujayojpaqxryuqi.pdf ./txt/work_3ztz4ncxbfbujayojpaqxryuqi.txt
