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

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.

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

Today, finches occupy every continent except Australia, most eating seeds, a diet for which their bills are well-adapted. Over the past several million years, 13 Galapagos finches have come to occupy the varied Galapagos islands. Finches found on these islands have very different bill shapes and feeding behaviors than finches found on the nearby mainland. Darwin gathered a considerable amount of field data on these finches and their habitats to propose his findings.What major factors allowed the birds to adapt to their new environment?Question 1Select one:A.genetic drift followed by mutationB.the founder effect followed by reproductive isolationC.mutation and disruptive selectionD.mutation followed by reproductive isolationE.mutation and increased reproductive fitness of some offspring

Finches on the Galapagos islands exhibit remarkable variation in the shape of their beaks. What best explains this variation?Multiple choice question.Differences in their feeding habitsSubtle differences in the climate of different Galapagos islandsDifferences in their predatorsDifferences in their breeding strategies

After a drought, the only species of tree that survived had very large seeds. Many generations later, the finches with largest beaks increased in number and the ones with smaller and medium-sized beaks decreased in number.How is this BEST explained?Elimination ToolSelect one answerAThe finches with small and medium beaks had to work harder than those with larger beaks to crack open the large seeds. The more they used their beaks, the larger their beaks became, so they were able to obtain enough food to survive, reproduce, and pass the traits of large beaks to the next generation.BThe finches with the large beaks were better at eating the large seeds than those with smaller beaks, so only the birds with large beaks obtained enough food to survive, reproduce, and pass the trait of large beaks to the next generation.CThe finches with smallest beaks grew their beaks so that they would be better able to eat the large seeds and get enough food to survive, reproduce, and pass the trait of large beaks on to the next generation.DIt was a chance occurrence that all the individual finches’ beaks in the next generation were larger. Therefore, they were able to eat the large seeds and get enough food to survive, reproduce, and pass the trait of large beaks to the next generation.
