Homology vs. Homoplasy |
Homology- indicate same organ different organism under variety of forms/function due to evolutionary development from common ancestor Homoplasy- indicates given characteristics evolve more than once with phylogeny in different organisms, not present in last common ancestor |
|
|
Process Homology |
similar organ originated from commonly inherited modular genetic pathways |
|
|
Co-option |
occurs natural selection finds new uses of existing traits includes genes, organs, and other structures |
|
|
Developmental System Drift |
propose as long as morphological feature itself dont change (preserve organism interxn with environment) underlying molecular pathway specify can be altered without evolutionary penalty |
|
|
Candidate Gene Approach |
based on mutant phenotypes in model species, pick genes seem likely involved with change in Your Favorite Trait. I.D homologs of candidate genes in taxa of interest to study whether expression patter appear change in conjunction with evolution of YFT. |
