Introduction

The term “contemporary evolution” is typically used in reference to ongoing or recent genetically based (heritable) phenotypic changes taking place in wild populations. In some cases, the genetic and genomic basis for these phenotypic changes can be identified and documented. Contemporary evolution is most apparent when organisms experience dramatic environmental changes, especially due to human causes such as commercial fisheries, climate change, pollution, or urbanization. Contemporary evolution then influences a number of evolutionary and ecological processes, such as ecological speciation, population dynamics (including evolutionary rescue), community structure, and ecosystem function. As a result, contemporary evolution has important applications in conservation biology, environmental sciences, and sustainability science.

General Overviews

The first conceptual review of contemporary evolution, which also coined the term, was Hendry and Kinnison 1999. That paper also advocated and advanced the use evolutionary rate metrics to analyze and compare rates of phenotypic change. Contemporary evolution was later alternatively defined as evolution occurring over ecological time scales in Hairston, et al. 2005, which also argued for the importance of ongoing evolution in shaping ecological processes. Hendry 2017 provides a general overview of the various factors shaping contemporary evolution and the ecological consequences of that evolution. Although the study of contemporary evolution emphasizes changes that take place in wild populations, studies of selection in laboratory or other controlled populations have taught us much about how evolution responds to changes in selection, as reviewed in Kassen 2014.
