Complex Adaptive Traits Flashcards
Mousetrap Argument
Argues that complex traits cannot evolve through natural selection because without all of their parts, they will not function; this argument tries to go against evolution
Complex Adaptive Traits
Traits that are comprised of multiple components
Advantageous Intermediates
Intermediate forms of the complex trait still provide an advantage in survival and thus are acted on by selection
Exaptations (co-opting)
A trait used for one purpose is co-opted for a different purpose in the complex trait
Genetic architecture of traits - Gene duplications
release constraints to evolve in the duplicate copy
Pleiotropy
One gene affects multiple traits or one gene affects trait at multiple developmental stages
