Cities are ubiquitous and, though a novel phenomenon by evolutionary standards, provide home for many species and exert particularly strong selection pressures on them. They thus offer unique opportunity to study rapid processes. We conducted scoping review of published studies documenting processes in urban environments, focusing primarily more recent work. Unfortunately, cities have not been attractive environments biological research remain poorly studied, despite slowly growing interest years. Nonetheless, we found the effects mutation, genetic drift, cities. However, show some geographic bias were always as conclusive might be desired. There is even support incipient speciation. Evidence across board less abundant than desirable, suggesting need data collection. The setting, with its stronger selection, common intermixing, abundance both human widespread potential non-human zoonosis hosts human-associated offers great opportunities further document evolution action explore conservation implications.

Abstract Urbanization is one of the most significant contributors to Anthropocene, and urban evolutionary ecology has become an important field research. While it commonly assumed that cities impose new stronger selection, contradictory assertion selection may be relaxed in also frequently mentioned, overall, our understanding effects urbanization on natural incomplete. In this review, we first conduct a literature search find evidence for patterns phenotypic traits including morphology, physiology, behaviour life history, non‐urban populations animals plants. This reveals coefficients context are scarce ( n = 8 studies providing gradients/differentials include total 200 coefficients) lack standardized methods hinders quantitative comparisons across (e.g. with meta‐analysis). These studies, however, provide interesting insight agents shaping improve mechanistic processes at different spatial scales. We then perform second review genomic assessing intensity cities, genome non‐human populations. returns 383 articles, only 34 these truly investigate footprints associated urbanization, study provides genetic coefficients. Here again, highly heterogeneous approaches, yet some strong adaptation. neither nor were able quantitatively assess versus habitats. Thus, propose roadmap how future should metrics facilitate mega‐ or meta‐analyses explore generalized selection. Read free Plain Language Summary article Journal blog.
