Domestication occurs when one species (mostly humans, but not always) takes over the care and reproduction of another, eventually artificially evolving a new lineage, tailor-made for their own purposes. Human-driven domestication has produced hundreds of breeds of livestock, crops, pets, and more.

Artificial breeding can produce wildly varying results. The huge diversity of dog breeds are all bred from one or a few ancestral populations, and all of these plants are breeds of one wild species.

In the Episode, we also discussed the famous Fox Farm Experiment! Learn more here and find more references and some videos of the foxes here!
