How does evolution produce new species

WebFor the longest time, I've held the assumption that to be a member of a species is to have innate (mostly genetic) components. I.e., without a specific trait (s) (e.g. strips on zebra, white fur on polar bears, Indian rhinos with one horn), that organism is not a member of a given species. I'm guessing this view is also held by the general ...

It is a non-random change in allele frequencies from one generation to the next.

WebNew alleles originate by mutation, a permanent change in the nucleotide sequence of DNA. Mutation is the ultimate source of the genetic variation that serves as raw material for evolution.
