Document Summary
The teeth never stop growing and larger teeth are hardest on the front and have softer inner sides. This keeps the teeth sharp to gnaw at trunks and branches. Due to foresting, trees in the area have a selection toward thicker bark. This is an example of: directional selection, stabilizing selection, disruptive selection, natural selection, sexual selection, which is not a reason why variation still exists when selection is strong, which is not one of the 4 agents of evolution. Females cannot always mate with the best" male. Trait that is being selective for has relatively high fitness but is not absolute. Trait that is being selected against will have no reproductive success. None of the above: genetic drift, gene flow, natural selection, sexual selection, mutation, a couple living in kenya have 5 children. One was diagnosed with sickle cell anemia and year later malaria takes the life of 1 other child.
