> For millennia, people have changed the earth. As mentioned, it is part of life to alter the world in which we live. Native peoples used fire to clear and fertilize the land, colonizers transported diseases and invasive species that reshaped ecosystems, and agriculturalists altered the evolutionary track of the plant and animal worlds through selective breeding.  -- P Wapner. 2010.

> Humans have been keeping honey bees, Apis mellifera, in artificial hives for over 7000 years. Long enough, one might imagine, for some genetic changes to have occurred in domestic bees that would distinguish them from their wild ancestors. ... Harpur et al. (2012) show that the migrant honey bee populations established in Canada are mixtures of most of the subspecies of Europe and that, at a population level, commercial honey bee populations are more diverse than the European populations from which they are derived. -- Oldroyd, B. P. (2012). Domestication of honey bees was associated with expansion of genetic diversity. Molecular Ecology, 21(18), 4409-4411.
