Example of directional selection

Peacocks evolving to get colorful feathers to mate with females and stand out to females
Example of Sexual Selection
Example of sexual selection

When the favored trait is extreme and the population shift is extreme
Directional Selection
Stabilizing Selection
No extreme genes are favored, and the most common genes are favored
Human babies have evolved to not be too light or too heavy to ensure survival
Example of stabilizing selection
No extreme genes are favored, and the most common genes are favored
Stabilizing Selection
Third principle of natural selection
Populations have more population than resources available
Example of stabilizing selection
Human babies have evolved to not be too light or too heavy to ensure survival
Directional Selection
When the favored trait is extreme and the population shift is extreme
Certain inherited traits make it easier to thrive and reproduce
Natural Selection
First principle of natural selection
Different members of a population have different physical traits
When traits that help with mating and survival among the same gender are preferred
Sexual Selection
When both of the extreme traits are preferred over the in between
Disruptive Selection
