In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution .
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.
Coevolution is a process in which two or more species influence the evolution of each other. All organisms are influenced by life around them; however, in coevolution there is evidence that genetically determined traits in each species directly resulted from the interaction between the two organisms.
This innovation causes a major burst of animal coevolution. First freshwater pelomedusid turtles. Earliest krill. 120 Ma Oldest fossils of heterokonts, including both marine diatoms and silicoflagellates. 115 Ma First monotreme mammals. 114 Ma Earliest bees. [94] 112 Ma Xiphactinus, a large predatory fish, appears in the fossil record. 110 Ma
In biology, co-adaptation is the process by which two or more species, genes or phenotypic traits undergo adaptation as a pair or group. This occurs when two or more interacting characteristics undergo natural selection together in response to the same selective pressure or when selective pressures alter one characteristic and consecutively alter the interactive characteristic.
The need for this new narrative stems not from any single recent discovery or eureka moment, but from the cumulative weight and synthesis of many discoveries about the functions and evolution of ...
Adaptation – Process that fits organisms to their environment; Adaptive radiation – A process in which organisms diversify rapidly from an ancestral species; Coevolution – Two or more species influencing each other's evolution; Concerted evolution; Convergent evolution – Independent evolution of similar features
In other words, a gene that confers a vital biological function can become dispensable for an individual organism if its community members express that gene in a "leaky" fashion. Like the Red Queen hypothesis, the Black Queen hypothesis is a theory of co-evolution.
