This conclusion follows from the differences in barriers to horizontal flow of information — there are both weak and strong barriers in biology but only weak ones in anthropology in biology there are both pre-zygotic and post-zygotic barriers to gene flow, which refer to those acting to prevent the formation of a zygote and those acting after. Horizontal gene transfer horizontal gene transfer (hgt) is the introduction of genetic material from one species to another species by mechanisms other than the vertical transmission from parent(s) to offspring these transfers allow even distantly-related species (using standard phylogeny) to share genes, influencing their phenotypes.
