Population biology

Population biology

Population biology is a study of biological populations of organisms, especially in terms of biodiversity, evolution, and environmental biology. The term "population biology" is often used interchangeably with population ecology, although the term with biology is more frequently used when studying diseases, viruses, and microbes, and the term with ecology is used more frequently when studying plants and animals.

Malthus can almost be considered an early population biologist, even though his training was in economics and the term population biology had not been coined. Although his work An Essay on the Principle of Population only dealt with humans for the most part, it gave Charles Darwin some inspiration for his seminal work The Origin of Species.
