Detailed explanation-1: -For example, long tails in cats could be classified as good and short tails as bad. False. Biologists do not assign a moral value, judgment, or statement of worth to particular traits, as this is outside of the domain of science.
Detailed explanation-2: -Biologists do not categorize particular traits as good or bad because they are only identifying a quality or feature that aids a living organism in surviving within the ecosystem.
Detailed explanation-3: -What does it mean for a trait, such as light skin coloration, to be under negative selection in equatorial Africa? Relate negative selective pressure to what we know about MC1R allele diversity among African populations. It means that there is selection against that trait.
Detailed explanation-4: -Biologists sometimes say that “natural selection depends on the specific environment where a species lives.” What does this statement mean? They are saying that the change will only stay if it improves the chance it will survive and pass on the trait and others without the trait will slowly die off.
