Urban evolution

Urban evolution refers to the heritable genetic changes of populations in response to urban development and anthropogenic activities in urban areas. Urban evolution can be caused by mutation, genetic drift, gene flow, or evolution by natural selection.[1] Biologists have observed evolutionary change in numerous species compared to their rural counterparts on a relatively short timescale.[1][2]

Strong selection pressures due to urbanization play a big role in this process. The changed environmental conditions lead to selection and adaptive changes in city-dwelling plants and animals.[3][2] Also, there is a significant change in species composition between rural and urban ecosystems.[4]

Shared aspects of cities worldwide also give ample opportunity for scientists to study the specific evolutionary responses in these rapidly changed landscapes independently. How certain organisms (are able to) adapt to urban environments while others cannot, gives a live perspective on rapid evolution.[3][2]
