Imagine a bird species in which many individuals spend their first summer of adulthood helping other members of the population raise offspring instead of breeding themselves. Which of the following explanations is MOST consistent with the hypothesis that helping behavior evolved by kin selection? O Populations with a high frequency of helpers send out more migrants than populations in which all individuals breed in their first season of adulthood. O Individuals that help relatives feed their young produce fewer of their own offspring in a lifetime than individuals that begin breeding in their first year of adulthood. O Helpers learn to forage more efficiently by observing kin than non-kin. O Helpers more frequently direct their assistance toward aunts and uncles than toward full siblings.

Ancestors of the beach mouse mayhave exhibited variations in their coat color. Because of the prevalence of visualpredators, the better-camouflaged (lighter) mice in the beach habitat may havesurvived longer and been able to produce more offspring. Over time, a higher andhigher proportion of individuals in the population would have had the adaptation of lighter fur that acted to camouflage the mouse in the beach habitat.
According to Hamilton’s rule,(A) natural selection does not favor altruistic behavior thatcauses the death of the altruist.(B) natural selection favors altruistic acts when the resultingbenefit to the recipient, corrected for relatedness, exceedsthe cost to the altruist.(C) natural selection is more likely to favor altruistic behaviorthat benefits an offspring than altruistic behavior thatbenefits a sibling.(D) the effects of kin selection are larger than the effects ofdirect natural selection on individuals.
A group of 50 men and 50 women establish a colony ona remote island. After 50 generations of random mating,how frequent would a recessive trait be if it were at afrequency of 1/500 back on the mainland? The population remains the same size over the 50 generations, andthe trait has no effect on fitness.
Competition is most intense between members of a(n)_______ . Predators and their prey act as agents of__________ on one another, resulting in a formof evolution called______ . This results in the evolution of characteristics called______ that help both predators and their prey survive andreproduce.
Which of the following is not required for a behavioral trait toevolve by natural selection?(A) In each individual, the form of the behavior is determinedentirely by genes.(B) The behavior varies among individuals.(C) An individual’s reproductive success depends in part onhow the behavior is performed.(D) Some component of the behavior is genetically inherited.
The digger bee’s “postcopulatory courtship” consists of elaborate tactile stimulation that the male provides his partner after she has accepted his sperm. Why is this behavior a Darwinian puzzle, and what might its adaptive value be? Dont' write from any online source.
Lithobates clamitus. also know as the green frog and bronze frog can range in in skin color from pure to brown to pure green and a mixture of both. As their habitats change frogs with a mixture of both colors have a higher fitness as they are better able to hide from predators. 1. If the change in the distribution of this trait is the result of natural selection, name the mode of selection (ie: Balancing, Disruptive, etc...) 2. If a small group of male frogs end up joining this population from a different population of frogs, which process of selection describes the movement of alleles present in the male frog? 3. The process you named in “c” ________ the genetic variation in the population that the male frog joined? (increase, decrease, or stay the same?)
What is the proximate cause of male deer fighting over females?a. to determine their supremacy over other malesb. to injure other males so that these other males cannot mate withfemalesc. to maximize the number of genes they pass ond. because changes in day length stimulate this behaviore. because fighting helps rid the herd of weaker individuals

Many species of animals make alarm calls, which warn others in their group that a predator is approaching. Alarm calls also attract the atten- tion of the predator, making it more likely that the individual making the call will be eaten. Why might natural selection favor the evolution of alarm calls in a species? How might you test that hypothesis?
When Charles Darwin discovered the various finch species on the Galápagos islands, he was surprised to find so many different but related species in such a small geographic area. Which of the following best illustrates the correlation between competitive advantage and an individual’s traits in a particular environment? Different islands had very different food resources available, and only individuals that were adapted to eat those food resources survived and reproduced on that island. Finches had no natural predators on the island before Darwin’s voyage, allowing them to prosper on the islands. Competition between different species for food resources led to resource partitioning of the ecosystem. Mating behaviors in finch species ensure that different species of finch will not interbreed with one another.
An individual bird may behave apparently altruistically in a way that decreases its own fitness (by cost C) yet increases the fitness of another individual or set of individuals (by benefit B each). According to Hamilton’s Rule, if natural selection favors this behavior to help four grandchildren, it should also be favored when the recipients are Group of answer choices eight first cousins All the given answers are correct two siblings four nieces
