Question

Give one example of how natural selection can change the distribu- tion of a trait.

Answer 1

One example would involve the appearance of black/white lizards in the dessert. Since the white lizards would blend in the sand, they would get eaten less allowing natural selection to favor them over the black lizards. Over time, this will create an unequal distribution of lizards as there will be many more white lizards than black.

Hope this helped :)
