Why might natural selection act more strongly on traits that improve reproductive success early in life rather than later in life?
why do females have a greater disadvantage compared to males concerning sexual reproduction? How has this difference between the sex shape sexual selection in general? Choose one form of communication and explain how it is used by competing sex is attracting a mate.
Which 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.
Which of these interactions are examples of sexual selection? Select all that apply. A change in food resources on an island favors finches with medium-sized beaks. Finches with small and large beaks disappear from the island after a few generations. Female flies prefer to mate with males that have longer eyestalks. These eyestalks provide no survival advantage, but longer eyestalks become more common over generations. Male seals compete for territory and access to clusters of female seals. The more aggressive male seals tend to secure the largest territories and clusters.

What sorts of studies would we undertake in order to confirm that human mating behaviors are truly driven by biological forces, e.g., evolutionary fitness, rather than cultural or societal advantages?

Assume 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.
Kin Selection - Ground squirrels will often give a warning call when they see a predator, altering the other ground squirrels to the danger. Calling behavior draws attention to the calling squirrel. This being the case, why would natural selection favor this altruistic behavior? Consider this - female squirrels are 70% more likely to make a warning call than male squirrels. Also consider, male squirrels leave the colony when they reach maturity, while female squirrels stay in the colony they are born in. Explain how natural selection is working here!
If natural selection has no foresight,how can it explain features that seem to prepare organisms for future events? For example, deciduous trees at high latitudes drop their leaves before winter arrives, male birds establish territories before females arrive in the spring, and animals such as squirrels and jays store food as winter approaches.
Which of the following situations will lead to natural selection? a. The seeds of two plants land near each other and one grows larger than the other. b. Two types of fish eat the same kind of food, and one is better able to gather food than the other. c. Male lions compete for the right to mate with females, with only one possible winner. d. all of the above
