What Makes Us Human?
... We now know that inherited variation comes about through mutation, random assortment of chromosomes and genes, sexual reproduction where two parents contribute (different) genes to the offspring, and out breeding between different populations of the same species. ...

The making of the Fittest: Natural Selection and Adaptation

The differential survival and reproductive success of individuals with different traits causes populations to change over time. • By comparing organisms living today with the fossil record of extinct organisms, it is possibl ...
