WebMar 23, 2024 · Introduction. Gene co-option, i.e., repurposing a partial or entire pre-existing genetic network in an unrelated developmental context, is a major mechanism underlying the rapid evolution of novel complex traits. 1 After co-option a genetic network often undergoes adaptive modifications, which further alter the morphology of the novel trait. 2, … Webco-opt meaning: 1.

Behavior, like morphology, has both structure (what it looks like) and function (what it does). Julian Huxley, a founding father of ethology, had the fundamental insight that behavioral displays often evolve in one context, then change function later in evolution.

Co-option (also co-optation, sometimes spelt coöption or coöptation) has two common meanings. It may refer to the process of adding members to an elite group at the discretion of members of the body, usually to manage opposition and so maintain the stability of the group.
