URBAN FLORA'S HIGH SPEED EVOLUTION


recent studies show that weeds are able to adapt to urban conditions very rapidly. reason for this is the split-up of their habitat. but for them this is not a problem at all: instead of investing energy in complex flying divices to fan out (such as the so called Holy Pippau/crepis sancta does), they focus on creating seeds that are heavy enough to fall down from the plant directly and germinate at the same location. makes sense, since it is not very likely the flying seeds will fall down on a piece of fertile soil.
remarkably is that this process of adaptation from rural to urban only takes a few seasons!
so now we know. not only humans are capable to adjust to city life...
