Members of some species will sound warning calls when they notice predators even though this increases the likelihood the predator will find the individual that provided the alarm. The evolution of such behaviors provides evidence for which hypothesis?   A. Evolution selects behaviors that increase the ability of individuals in a species to camouflage.   B. Evolution selects behaviors that increase the likelihood that individuals in a species will reproduce.   C. Evolution selects behaviors that increase the the likelihood that individuals in a species that share similar genes will survive and reproduce.   D. Evolution selects behaviors that increase the likelihood that individuals in a species that share similar genes will migrate.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
