Natural Factors
2 factors of natural selection that do not include a change in the environment or pretitors?
Mutations in the genetic code would be one form of evolution, but I'm not sure if that is what you are looking at.
Competition for scarce resources would be an example that would cause natural selection.
Changes and/or mutations in one species in a balanced ecosystem can cause another species that interact with the first species to undergo natural selection.
Genetic drift - species migrating further apart and naturally adapting to different environments
I hope that helps!
