To be an active characteristic or trait causing natural selection to take place, the trait has to have the following features: Heritability. A trait can only influence evolution through natural selection if it is passed on from parents to descendants. Functionality. WebNatural selection can only work on existing variation within a population. Such variations arise by mutation, a change in some part of the genetic code for a trait. Mutations arise by chance and without foresight for the potential advantage or disadvantage of the mutation. In other words, variations do not arise because they are needed. ...
