Description

This activity maps to the OpenStax biology textbook, 45.1 Population Demography

Student Introduction: Organisms are generally assumed to exhibit traits that are adaptive to the specifics of the environment in which they are found, as a result of natural selection. Some studies have indicated, however, that certain traits appear to be maladaptive, yet they are maintained within a population. This maladaptation may be a result of genetic constraints (such as a trait that is genetically correlated with another trait that is changing under selection), recent or fluctuating changes in selective pressures, conflicts between natural selection and sexual selection (for example, the long tail feathers of male peacocks), or gene flow (the movement of genes between two or more populations). The latter is the focus of this module.
