Dec 6, 2015 · This may occur because researchers may believe that convergence can only occur in the presence of some kind of limitation on evolution; if it is thought that convergence can only be caused by adaptation in response to a shared set of selective pressures, for example, then it becomes easy for researchers to assume that ‘convergence is the independent acquisition of similar characteristics by ...

Apr 27, 2017 · Convergent Evolution Definition. Convergent evolution is the process in which organisms that are not closely related independently evolve similar features. Adaptions may take the form of similar body forms, colors, organs and other adaptions which make up the organism’s phenotype. Convergent evolution creates analogous structures or ...
Aug 1, 2015 · An analysis of distance-based convergence among two crown-giant anoles (Anolis luteogularis and A. garmani) produces a C 1 of 0.50, indicating that evolution has closed 50% of the distance between these two taxa, a C 3 of 0.04, indicating that convergence is responsible for 4% of the total evolution in the two lineages leading from the most recent common ancestor to the tips, and a C 4 of 0.01 ...
Feb 27, 2023 · Investigations of functional convergence generally focus on aspects of form that relate to recurrent “everyday behaviour” (e.g., foraging, feeding, ventilation, locomotion, adhesion) that influences the survival of the organisms through the maintenance of homeostasis, and on aspects of social behaviour (e.g., communication) that involve intra- and interspecific interactions between ...
