Answer:
evolution occurs through genetics.
Explanation:
Organisms will not able to evolve by not hunting of human and global warming because these are environmental factors which bring some behavior changes while evolution occurs due to mutation. When sudden change occurs in the genetics of an organism due to chemicals, evolution will occur. About one million years is needed for evolution of an organism. In those species evolution occurs in which there is high rate of competition. Evidence shows that two species are closely related to each other are their physical features, DNA composition and same needs for survival.
