Reciprocal causation features in several explanations within contemporary evolutionary biology, including sexual selection theory, coevolution, habitat selection, and frequency-dependent selection. In these examples, the source of selection on a trait coevolves with the trait itself, therefore causation is reciprocal and developmental processes ...
He concluded that r/K theory was a once useful heuristic that no longer serves a purpose in life history theory. [43] More recently, the panarchy theories of adaptive capacity and resilience promoted by C. S. Holling and Lance Gunderson have revived interest in the theory, and use it as a way of integrating social systems, economics, and ...
Clarke later argued that frequency-dependent balancing selection could explain molecular polymorphisms (often in the absence of heterosis) in opposition to the neutral theory of molecular evolution. [9] Another example is plant self-incompatibility alleles. When two plants share the same incompatibility allele, they are unable to mate.
Biological applications of bifurcation theory provide a framework for understanding the behavior of biological networks modeled as dynamical systems. In the context of a biological system, bifurcation theory describes how small changes in an input parameter can cause a bifurcation or qualitative change in the behavior of the system.
In evolutionary biology, an evolutionary tradeoff is a situation in which evolution cannot advance one part of a biological system without distressing another part of it. In this context, tradeoffs refer to the process through which a trait increases in fitness at the expense of decreased fitness in another trait.
Kendall and Kylie Jenner‘s relationship with half-brothers Brody and Brandon Jenner has changed over the years, but the siblings still have love for each other. The Kardashian-Jenner Family: Get ...
In evolution, cooperation is the process where groups of organisms work or act together for common or mutual benefits. It is commonly defined as any adaptation that has evolved, at least in part, to increase the reproductive success of the actor's social partners. [1]
About 12% to 25% of married couples report breaking up and getting back together, says J. Kale Monk, Ph.D., an associate professor at the University of Missouri College of Education & Human ...
