Natural Selection

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

No, organisms do not decide to evolve; they change due to natural selection.

It refers to the concept of natural selection, where the fittest individuals are more likely to survive and reproduce.

Adaptations are traits that enhance an organism's ability to survive and reproduce in its environment.

The coloration of moths; light-colored moths are favored in environments with light-colored tree trunks.

They are less likely to survive and reproduce, leading to a decrease in their population over time.

Genetic variation provides the raw material for natural selection, allowing some individuals to have advantageous traits.

Environmental changes can alter which traits are advantageous, leading to shifts in the population over time.

Fitness refers to an organism's ability to survive and reproduce in its environment.

Yes, over long periods, natural selection can lead to speciation as populations adapt to different environments.
