WebThere are two general circumstances leading to sexual selection. One is the preference shown by one sex (often the females) for individuals of the other sex that exhibit certain traits. The other is increased strength (usually among the males) that yields greater success in securing mates. The presence of a particular trait among the members of ... WebThis line of thinking led to Darwin’s theory of: Natural Selection- mechanism by which individuals that have inherited beneficial adaptations produce more offspring on average than do other individuals. Nature is the selective agent. Characteristics are selected only if they give advantages to individuals. Takes many generations.
