The effects of the introduction of European livestock on the environments and peoples of the New World were not always positive. These results were taken to support the idea of adaptive introgression based on genetic resistance to infectious disease agents, and population genetic modeling was used to provide support for the role of selection in enriching for locus-specific African ancestry. It had the most significant effect on Ireland, where it promoted a rapid population increase until a potato blight ravaged the crop inbringing widespread famine to the area.

Having identified ancestry-enriched loci haplotypes in this way, they can be further interrogated with respect to their rates of evolution as well as the functions of the genes encoded. One can expect that such a profound human demographic transformation would occasion substantial evolutionary change at the genomic level. King Jordan, Phone:Email: ude.

This is an interracial dating services and personals site dedicated to those seeking real love. Many of these differences were likely to be neutral changes with no appreciable effects on fitness, whereas others were the result of adaptations to local selection pressures [ 1112 ]. In other words, introgression during the Columbian Exchange provided extensive standing genetic variation to New World populations, much of it with potential adaptive significance, which could have provided the raw material for numerous partial selective sweeps.

Specifically, I hypothesize that the process of human genome evolution stimulated by the Columbian Exchange was based in part on selective sweeps of introgressed haplotypes from ancestral populations, many of which possessed pre-evolved adaptive utility based on regional-specific fitness and health effects.
