Natural selection requires genetic variation, competition for limited resources, overproduction of offspring, and unequal reproductive success.The subset of finches that is capable of eating large seeds, while many others eat small seeds, is an example of which requirement?Multiple Choiceoverproduction of offspringgenetic variationunequal reproductive successcompetition for limited resources

Which is a correct statement about the evolutionary changes in the medium ground finch studied by Peter and Rosemary Grant?Multiple choice question.Climatic variation impacts seed size, which is a selective force on the competitive abilities of the birds.Climatic variation impacts seed nutritional content, which is a selective force on hatchling survival.Climatic variation impacts seed size, which is a selective force on beak size.Climatic variation impacts seed size, which is a selective force on the ability of birds to tolerate toxins.

Select observations and inferences that Charles Darwin made in support of natural selection.Multiple select question.There is competition among individuals for limited resources.Some individuals survive due to their inherited characteristics, making them more likely to reproduce.Organisms are varied and some variations are inherited.Natural selection can change the characteristics of a population over many generations.Individuals in a population share all of the same characteristics; thus, no variation can occur in future generations.More individuals are born than can survive to reproduce.Resources are usually available in unlimited supply.

Suppose in a population of a single bird species, natural selection favors medium-sized beaks. Birds with very small beaks cannot break open the seeds they feed on; birds with large beaks cannot reach into the fruit to get the seeds at all. Natural selection in this case results inA.stabilizing selection.B.convergent evolution.C.adaptive radiation.D.disruptive selection.

Ground finches with large bills are favored during times of drought, while ground finches with small bills are favored during times when water is abundant. This is an example of Blank______.Multiple choice question.diversifying selectionstabilizing selectionbalancing selectionoscillating selection

How does the climate drive evolution in the medium ground finch?Multiple choice question.The climate impacts interspecific competition, which increases the fitness of larger birds.The climate impacts the size of seeds, which acts as a selective force for beak size.The climate impacts the availability of suitable mates, which lowers the fitness of many birds
