Males of the bighorn sheep species fight one another to show females who is the dominant male and are more likely to mate with females.
Natural Selection
Mutation
Genetic Drift
Non-Random Mating
During a hurricane, a population of beetles almost gets completely wiped out. The only beetles that survived were lucky that they were in their nest at the time of the hurricane and had enough food to survive.
Natural selection
Genetic Drift
Gene Flow
Non-Random Mating
This is one of the mechanisms of evolution; it is a continuous process in which organisms with traits that make them better-adapted to their environment are more likely to survive and reproduce than organisms without such adaptations
Directional selection
Microevolution
Gene flow / genetic drift
Natural selection
The light mice can reproduce more successfully than the dark mice
The hawks eat more dark mice than light mice because the dark mice taste better
The hawks eat more light mice than dark mice because they can see the light mice more easily
The hawks eat more dark mice than light mice because they can see the dark mice more easily
