You're missing another remarkable ability of nature - coevolved species with humans. In essence, they keep evolving until humans find a use for them in their lives (be it personal, medical, industrial, etc) and then end up caring/nurturing them. Or another way to phrase it: The weeds evolve so they don't compete with the crops the human grows. A few examples come to mind: - "Clovers" fix nitrogen in the ground, other plants can take that nitrogen from the ground, some gardeners now intentionally keep this weed to benefit the plants they are growing for crops. I think the term is called "rotating cover crop". - "Comfrey" has incredibly long tap root which mines minerals and stores those in the leaves. Gardners/farms can plant comfrey, chop the entire top off, the decaying leaves release the minerals into the surface soil for the surround crop plants to utilize. Without comfrey, those minerals would of been locked away from the main crop. After the comfrey is cut, it grows back the leaves again and the gardener/farmer can repeat this cycle. - Some weeds attract beneficial insects to the garden/farm and thus benefit the main crop. Wise gardener/farmer would keep these around. For example, more bees means more insect pollinated fruit to be grown. The pattern with highly competitive specifies results in either extinction of one of the species or a mutual beneficial evolution. For example: - "Bull horn Acacia tree" - Ants and the tree have co-evolved that in the present they are highly depend on each other for survival. In the history, at one point when the ants and tree were introduced the ants brought a lot of acacia tree destruction followed by ant death because of loss of food source - but over time the trees that benefited the ants got selected along with the ants that were compatible with the trees.
