... should already be there before they invented the language. You can always attribute people's looks in a population to a possible etiology of founder effect, migration and basically gene drift. You dont always have to go the people just "evolved" that way. In order for people to ...

But what I was interested in was if a founder effect, or a bottle neck effect can ever leave any kind of lasting 'trace' in the genetic history of a species, so that for example you might ...
