Why do Some Species Thrive in Cities?

Urbanization poses challenges to wildlife, leading to the loss of native species. However, some species adapt and thrive in cities due to natural traits or genetic evolution. Examples include English Ivy, rock pigeons, and raccoons. Genetic changes in urban species, like New York City's white-footed mice, show adaptation to city life. Rapid evolution can occur when species face significant challenges, as seen in tomcod and urban weeds. Cities act as evolutionary laboratories, testing species' adaptability, though they are not necessarily beneficial for biodiversity.
