- Alternatively, selection may be performed during mating, where mating is done after a selection process of one of the sexes. The surviving individuals can pass on their (1) to the next generation. When these variations are sustained over a long time and the population changes so that it can no longer (2) with the parent population, a new species is said to have evolved.arrow_forwardWhat type of selection is representative of what would happen if the earth were to continually cool, and some bears, such as those with thin or no hair, moved south and other bears with very thick fur stayed up the north. In this type of selection event, both types of bears would be selected for. (a)disruptive selection (b)directional selection (c)stabilizing selection (d)sexual selectionarrow_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
- According to Darwinian evolution, there must be variation and selection. In the evolution of large claws in lobsters: What trait(s) might have been variable? What factors might have resulted in members of the population being selected? Speculate about why predatory cats such as the lion and the leopard have not evolved to be as fast as the cheetah. The elephant has evolved to be a great size, while the mouse has evolved to be relatively small. Explain how natural selection might favour a different size in each mammal species.arrow_forwardAccording 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.arrow_forwardNatural selection and artificial selection or selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. Changes in genetic traits have occurred over generations through both natural selection and selective breeding although the occur through different means. What characterizes only artificial selection? Choose all that apply. A) chickens that lay larger eggs are favored B) selection increases the chances of surviving C) selection make a species stronger and fit for survival D) selection favors the desired characters in the new organismsarrow_forward
- 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 abovearrow_forwardWhich of the following is not true of natural selection?(a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traitsacquired during an individual’s lifetime (d) natural selection Test Your Understanding acts on a population’s genetic variability, which arisesthrough mutation (e) natural selection may result in changes in allele frequencies in a populationarrow_forward8) Darwin's finches are often used to illustrate evolution. Evaluate the finch beaks shown in the picture. Choose ALL of the statements that correctly explain the evolution of finch beaks. A) As the environment changed, the finches grew longer beaks to allow them to get food out of fruits. Eliminate B) Finches with longer beaks settled on the same island with smaller beaked birds. Over time, they bred, producing medium beaked birds that became more common in the population. C) There are finches with different types of beaks in the population. During a drought, those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait on to offspring. D) A random mutation introduced the shorter, thicker beak into the population. However, those with thinner, longer beaks were better able to get nectar from the island's flowers. Those birds with the shorter, thicker beaks were unable to get enough food to survive.…arrow_forward
- The Pipidae are a family of tongueless frogs that have one or more claws on their toes. While observing these frogs, you notice that males with more claws had more opportunities to mate and father more offspring. You hypothesize that these frogs evolved to have more claws as an adaptive trait to improve reproductive success. To test this hypothesis, you must: 1.look for evidence of multiple claws in ancestors of Pipidae 2.determine if the number of claws is heritable 3.test whether other these males have any other adaptive traits 4.test whether males with no claws are able to matearrow_forwardEvolutionary biology What are 4 conditions in which natural selection favors altruistic behaviors in which the individual performs costly actions to benefit others?arrow_forwardEcology regarding sexual selection: In zebra finch females prefer males who have a larger yellow cheek patch. Researchers investigating this preference think that females must benefit from choosing males with large cheek patches. Provide three hypotheses regarding the direct, or indirect benefits, she might receive.arrow_forward
