I'm not convinced that they are still the same species; can one assert that we have, through artificial selection, induced speciation? One word: "dogs". (Are you skeptical that chihuahuas and huskies are the same species? Some dog breeds are incapable of mating successfully without artificial insemination, or reproducing effectively -- think of a great dane foetus gestating in a female chihuahua -- but within a small single-digit number of generations they can produce hybridised "mutts" that are interfertile. Similarly, the brassicae are pretty much the same thing.)
