Altruism is basically when a member sacrifices itself for the well being of the population. If the population that was protected has favorable traits, they will be naturally selected for and over generations become dominant in the population. If they weren't protected, the population could die out.

How does selection favor calling How does selection favor not calling?
Not
How is kin altruism related to natural selection?
Kin altruism is the tendency to behave in such a way as to provide benefit to a close relative at personal cost. One might think of sharing food, or calling out when a predator approaches. Natural selection is the differential replicative success of alleles. If one considers altruistic behaviour as (influenced by) the expression of a complex of alleles, then it is easy to see how aiding organisms that share most of your alleles (ie. relatives) would cause those alleles to spread throughout the population gene pool at an increased rate. In this manner, altruism could evolve as a result of natural selection acting on 'selfishly' replicating genes.
How can natural selection favor different phenotypes at different times?
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 will never favor those members of a population that have an extreme variation of a trait?
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.
When does natural selection work the best?
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.
Complex behavioral patterns such as altruism can evolve in a species as the result of natural selection?
Yes, altruism can evolve through natural selection when it provides benefits to the survival and reproduction of individuals who share the same genes. This can occur through kin selection, reciprocal altruism, or group selection, where behaviors that benefit others increase the inclusive fitness of individuals over time.
When natural selection favor the intermediate version of a characteristic it is called?
stabilizing selection

Why is genetic variation important for natural selection to drive evolution?
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.
Natural selection would favor which of the these rabbits in Antarctica?
It would favor white because then it could camouflage and hide from predators and would be most likely to survive

Forensic pathologist use evidence to find what evidence in favor of evolution and natural selection?
direct evidence is the observation as it occurs
Natural selection can favor traits that make an animal more vulnerable to predators if those animals?
Leave more offspring
How does natural selection favor timid mice over bold mice?
Timid mice are less likely to be caught by a predator.
What were Darwin's best arguments in favor of his theory of evolution what were the most serious objections to it?
Darwin's best argument in favor of the theory of evolution was natural selection. The most serious objections came from religion.
