- Only a few hundred of the more than 200,000 speciesof plants have been domesticated for human use. Oneexample is the almond. The domestic almond is nutritiousand harmless, but its wild precursor can cause cyanidepoisoning. The oak makes potentially nutritious seeds(acorns) that contain very bitter-tasting tannins. Ifwe could breed the tannin out of acorns, they mightbecome a delicacy.
