A、有些人希望除掉它们，但不可能。反而这些动物与人越来越多联系(最后一段：攻击人类、人类喂食它们以至于它们住得离人们近) 英文原文阅读 Urban environments can exert novel selective pressures on organisms sometimes leading to new adaptations. For example, the weedCrepis Sancta, found in France, has two types of seed, heavy and fluffy. The heavy ones land near the parent plant, whereas the fluffy seeds float further away on the winD、In urban environments, seeds that float far often land on infertile concrete. Within about 5-12 generations the weed has been found to evolve to produce significantly more heavy seeds than its rural relatives.Among vertebrates, a case is urban great tits, which have been found to sing at a higher pitch than their rural relatives so that their songs stand out above the city noise, although this is probably a learned rather than evolved response. Urban silvereyes, anAustralian bird, make contact calls that are higher frequency and slower than those of rural silvereyes.As it appears that contact calls are instinctual and not learnt, this has been suggested as evidence that urban silvereyes have undergone recent evolution so as to better communicate in noisy urban environments. Many NorthAmerican species have successfully adapted to urban environments and are thriving. Typical examples include coyotes, rabbits, raccoons, squirrels,opossums, deer and red foxes. This has led to conflict with humans, as these animals open garbage bags in search of food, eat food left out for pets, take the pets themselves, feed on prized garden plants, dig up lawns, and so on. There may be some concern that coyotes pose a risk to small children and that they should not be left unsupervised in areas where coyotes are known to inhabit. While there are media accounts of alligators being found in sewer pipes and storm drains, most experts think that such ’sewer alligators’ are unlikely to sustain a breeding population in such an environment.Animals known to dwell within human habitations include house mice, cockroaches, house centipedes
