Pairwise or specific coevolution, between exactly two species, is not the only possibility; in multi-species coevolution, which is sometimes called guild or diffuse coevolution, several to many species may evolve a trait or a group of traits in reciprocity with a set of traits in another species, as has happened between the flowering plants and ...
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.
Pairwise coevolution When Darwin received an orchid from Madagascar whose nectary was one and a half feet long, he surmised that there must be a pollinator moth with a proboscis long enough to reach the nectar. [1] In its attempt to get the nectar, the moth would have pollen rubbed onto its head, and the next orchid visited would then be ...
By definition, coevolution yields heritable, genetic change among species over time, similar in the long run to the direct mechanisms of genetic sharing noted above. All species are subject to ...
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.
Coevolution; Coextinction ... Julian Huxley adopted Rensch's terminology as "cladogenesis" with a full definition: ... (it is unclear if this is the pairwise distance ...
Evolutionary game models have been created for pairwise and multi-species coevolutionary systems. [58] The general dynamic differs between competitive systems and mutualistic systems. In competitive (non-mutualistic) inter-species coevolutionary system the species are involved in an arms race – where adaptations that are better at competing ...
BLOSUM 62 is a matrix calculated from comparisons of sequences with a pairwise identity of no more than 62%. Other PAM matrices are extrapolated from PAM1. Based on observed alignments; they are not extrapolated from comparisons of closely related proteins. Higher numbers in matrices naming scheme denote larger evolutionary distance.
