"How fast can evolution occur?" doesn't seem like a meaningful question. If evolution is defined as a significant change in a population's gene distribution, it can occur in an arbitrarily short period of time.
- arakyd 17y agoApparently they define it as noticeable changes in phenotype. I would have guessed speciation.
- lacker 17y agoIt's hard to define speciation though. If two groups refuse to mate with each other, but they could in a lab, are they speciated? What if artificial semination works but naturally doesn't? Etc.
