Table 1 Examples of evolution in noncommensal species in response to urbanization.

Columns show species’ common and scientific names; the region of study (Africa, AF; Asia, AS; Europe, EU; North America, NA); the maximum number of cities examined in a single study; whether studies examined molecular genetic (G) or heritable phenotypic (P) evolutionary changes; and the mechanisms of evolution examined (mutation, U; genetic drift, D; gene flow, M; selection, S). A comprehensive list and description of species studied is included in table S1.
