Sexual selection favors individuals with traits that increase their ability to obtain mates, such as mating calls in crickets. using this example, propose a scenario where sexual selection could contribute to divergence in sympatric speciation. drag the terms on the left to the appropriate blanks on the right to complete the sentences. male(s)female(s)cool forest floorwarm forest canopyvariation in calls could occur, such as a lower-pitched call at the and a higher-pitched call in the in the could start to prefer with lower-pitched calls, and in the could start to prefer with higher-pitched calls, creating genetic isolation. over time, genetic divergence could occur between the two populations.

variation in male calls could occur, such as a lower-pitched call at the cool forest floor and a higher-pitched call in the warm forest canopy. Females in the forest floor could start to prefer males with lower-pitched calls, and females in the canopy could start to prefer males with higher-pitched calls, creating genetic isolation. Over time, genetic divergence could occur between the two populations.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
