Nature loves to make no sense a lot of the time.
Nature can't think, it just goes along with what works so far- otherwise, Humans would be giant-bionic super-soldier's that don't haft to eat by now.
No, the reason why nature favour's different sizes in most animals is probably because a long time ago, a event happened, causing animals to adapt to where the males were larger, and the females were smaller.
That was probably because the event caused many baby's to die, and so then the females (who were not a different size) died because they often fought to defend there offspring.
So, afterwords, the male took the role of protection.

Jean-Baptiste Lamarck believed in the theory of inheritance of acquired characteristics, which proposed that organisms could pass on traits that they acquired during their lifetime to their offspring. He also believed in the idea of evolution, suggesting that organisms change over time in response to their environment. However, Lamarck's ideas have been largely discredited in favor of Charles Darwin's theory of natural selection.
Lamarck illustrated his theory of acquired traits using the example of the giraffe. He proposed that ancestral giraffes stretched their necks to reach higher leaves, and this effort resulted in longer necks over generations. According to Lamarck, these acquired characteristics were then passed on to their offspring, leading to the longer necks observed in modern giraffes. This idea, however, has been largely discredited in favor of Darwinian evolution by natural selection.
Lamarck's hypothesis of use and disuse posits that organisms can develop traits based on their needs and behaviors during their lifetime. According to this idea, structures that are frequently used become stronger and more pronounced, while those that are not used deteriorate or diminish. He believed these acquired traits could then be passed on to the next generation, leading to evolutionary change over time. This concept was later largely discredited in favor of Darwinian natural selection.
If there were no predators in the forest, the color of the moth might not change significantly over time, as natural selection would have less pressure to favor certain colors for camouflage or survival. However, factors such as environmental changes, mating preferences, and genetic drift could still influence color variations. Without predation, the moth population might exhibit a wider range of colors due to reduced selection for cryptic coloration. Overall, while the absence of predators could lead to some changes, they would likely be less pronounced compared to a scenario with active predation.
Animal sacrifice was carried out in many cultures as a way to appease gods or deities, seek their favor, communicate with the spiritual world, or as a form of thanks giving for blessings. It was also believed to ensure fertility, prosperity, and protection for the community.
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.
Leave more offspring

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.
It would favor white because then it could camouflage and hide from predators and would be most likely to survive
direct evidence is the observation as it occurs
Timid mice are less likely to be caught by a predator.
Darwin's best argument in favor of the theory of evolution was natural selection. The most serious objections came from religion.
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.
Natural selection works best in environments where there is variation among individuals in a population, leading to differences in survival and reproductive success. It is most effective when environmental pressures, such as predation, competition, and resource availability, create challenges that favor certain traits over others. Additionally, natural selection is enhanced when the traits being selected for are heritable, allowing advantageous characteristics to be passed on to future generations.
