What is a "deme" in biological terms?

A "deme" refers specifically to a local population of interbreeding organisms that share a common gene pool. Within the context of population biology and genetics, demes are important because they help researchers understand how populations evolve over time, considering factors like genetic drift and natural selection. Members of a deme tend to mate with one another more frequently than with individuals from other demes, which can lead to distinct genetic variations and adaptations that are specific to that local population.

Understanding the concept of a deme is critical for studying the dynamics of populations and their evolutionary processes. It showcases how local environmental conditions and social structures can influence reproductive behaviors and overall genetic diversity in natural settings. This knowledge is essential for grasping broader concepts in evolutionary biology and conservation efforts.
