The act of agriculture itself is by definition selective breeding. For plants, taking them out of their natural environment with its co-occuring species, mycorrhizal networks, mineral composition and distributive species and sewing them by hand in a novel environment constitutes in itself a hugely genetically significant act. Even first-round seeds that germinate at all could show substantially different aggregate characteristics than those of the original wild population. For animals, those that may be caught for raising are in all probability the children of less aggressive parents. Feeding over time will cause more domestication and the removal of environmental stressors that had maintained levels of fitness for the natural pressures and begin to change them instantly. Both cases would only accelerate over generations, as it is a rare human who will later go and obtain seed or animals from the wild once a conveniently captive population is already available for breeding. I've come to the conclusion that humans, in writing their own histories, frequently give themselves far too much credit. We would do well to consider ourselves more humbly.
