Homoplasy - Study guides, Class notes & Summaries

Adaptation - A trait that benefitted an organism in a particular environment (level: individual) Allopatry - restriction of gene flow because of physical separation Physical geographic barrier: individuals, even if they wanted to, do not have the ability to mate with other group Analogy - evidence for convergent evolution Homoplasy usually come about because of analogies Analogous structure share a common function due to selection pressures Example: wings Artificial selection - some gene...
