Complex Adaptive Traits Flashcards
1
Q
Mousetrap Argument
A
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
2
Q
Complex Adaptive Traits
A
Traits that are comprised of multiple components
3
Q
Advantageous Intermediates
A
Intermediate forms of the complex trait still provide an advantage in survival and thus are acted on by selection
4
Q
Exaptations (co-opting)
A
A trait used for one purpose is co-opted for a different purpose in the complex trait
5
Q
Genetic architecture of traits - Gene duplications
A
release constraints to evolve in the duplicate copy
6
Q
Pleiotropy
A
One gene affects multiple traits or one gene affects trait at multiple developmental stages
