Natural selection is something that happens over time and is somewhat dependent on the conditions of climate and environmental changes. There are times when natural selection can favor different phenotypes, if and when the culture starts to seek out others with certain traits and characteristics to breed.
Natural selection can favor extreme variations of traits if they provide a survival advantage. For example, in a changing environment, individuals with extreme traits may be better suited to survive and reproduce. However, extreme traits can also come with disadvantages that may make individuals less likely to survive and reproduce.
This is called directional selection, where the environment selects for individuals with traits at one extreme of the phenotypic range. Over time, this can lead to a shift in the average phenotype toward that extreme.
The environment plays a key role in natural selection by exerting pressures that favor certain traits over others. Organisms with advantageous traits for a specific environment are more likely to survive and reproduce, passing on those traits to future generations. Over time, this process leads to the selection of traits that are well-suited to the specific environmental conditions of a given area.
Disruptive selection pressures favor rapid evolutionary changes because they create strong selective pressures on extreme phenotypic traits, driving the population towards the extremes and away from the average. This results in a rapid shift in the population's genetic makeup towards the extreme traits, facilitating rapid adaptation to new environmental conditions.
stabilizing selection
Selection favors calling in species that use vocalizations to communicate important information such as warning signals, mating calls, or territorial displays. Individuals who have a more effective or distinctive call may have a better chance of surviving, reproducing, and passing on their genes to the next generation. Over time, this can lead to the evolution of more complex or efficient calling behaviors in a population.

There are many websites that have great selections of wedding favor boxes. Websites such as, wedding favor gallery, wedding favor boxes, and get wed, all have great selection of wedding favor boxes.
It would favor white because then it could camouflage and hide from predators and would be most likely to survive

Darwin's best argument in favor of the theory of evolution was natural selection. The most serious objections came from religion.
direct evidence is the observation as it occurs
Timid mice are less likely to be caught by a predator.

Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
