Summary Introduction
Introduction: The phenomenon of natural selection is based on the evolutionary changes that occur within the population. This evolutionary change helps an organism to adapt better to its surroundings or environment. Natural selection brings about evolutionary adaptation in the organisms.

- In Biology of Beauty, Cowley found that contemporaryfemales are attracted to males with broad foreheads and strong chins, and that this effect persisted across different cultures. How did Cowley explain this result? A. This is a trick question- this attraction is culturally relative B. Males compete for access to females by developing these features as a form of male-male competition C. There is no evidence that females really are differentially attracted to males with these features D. Attraction to males with these features is adaptive for females because males with these traits are usually sexually mature and have healthy immune systems E. Only some human cultures value these traits as attractive.arrow_forwardWhich of these situations offers the lowest “opportunity for selection” for males? A. Females choose mates with a fancy ornament. B. Every female chooses one male to mate with for life. C. Locations that females need access to in order to reproduce are rare. D. Males fight each other for access to groups of females.arrow_forwardWhich of the following statements is a reason why females are usually the "choosier" sex? A. They expend fewer resources in caring for their offspring. B. They have higher potential fitness than males. C. They have fewer opportunities to contribute offspring than males. D. They directly compete with each other for mates.arrow_forward

Individuals are protandrous.B. It is better to be male when you are small and a female when you are big.C. Everyone begins life as a male.D. All of the abovearrow_forwardWhich of the following is the best description of sexual selection? a. Sexual selection is the differential reproductive success due to variation in acquiring immunity from mates. b. Sexual selection is the differential reproductive success due to variation in survival from social selection. c. Sexual selection is the differential reproductive success due to variation in acquiring mates or mating success. d. Sexual selection is the differential survival success due to variation in avoiding mates or mating success.arrow_forward
- Intrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.arrow_forwardDescribe how courtship behavior drives sexual selection. Use the peacock as an example.arrow_forwardYou are studying a genetically modified mouse that produces electric blue fur, which is not a fur color observed in nature. You notice that females prefer males that have the blue fur when given a choice test for mates. This result supports which of the following models of sexual selection? a. Sexual selection for indirect benefits b. Sexual selection for direct benefits c. Sexual selection for arbitrary traits d. None of the abovearrow_forward
- This hypothesis assumes that among male variation in the expression of ornaments reliably signals individual differences in overall quality of the males. It predicts that choosy females will produce offspring with higher survivorship or in better condition than those of less choosy females. A. Good genes process B. Bateman's principle C. Fisher-Zahavi process D. Fisher's runaway modelarrow_forwardThe fantastic coloration and behavioral displays in the birds of paradise that we watched in class were examples of differential sexual selection driven by: a. Female-female combat b. Male competition c. Female choice d. Intrasexual selectionarrow_forwardAssume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.arrow_forward
