Evolutionary

Evolutionary
Evolutionary research is concerned with the origin and descent of species, as well as their change over time, and includes scientists from many taxonomically-oriented disciplines. For example, it generally involves scientists who have special training in particular organisms such asmammalogy, ornithology, botany, or herpetology, but use those organisms as systems to answer general questions about evolution.
Evolutionary biology is partly based on paleontology, which uses the fossil record to answer questions about the mode and tempo of evolution,[52] and partly on the developments in areas such as population genetics[53] and evolutionary theory. In the 1980s, developmental biology re-entered evolutionary biology from its initial exclusion from the modern synthesis through the study of evolutionary developmental biology.[54] Related fields which are often considered part of evolutionary biology are phylogenetics, systematics, and taxonomy.
