Which of the following statements are supported by changes in beak depth of the Medium Ground Finch on the Galápagos island of Daphne Major over multiple generations? Select one: The direction of natural selection may reverse if the selective pressures change Random fluctuations in allele frequencies in response to extreme environmental conditions Irreversible changes in beak morphology under natural selection Rapid speciation of the large ground finch When random variation in populations is subject to a selective pressure, random evolutionary changes in the population will occur
Kelan H.
"Variation in traits can occur due to both the environment and genetics, and for evolutionary change, it doesn't matter as long as variation occurs." Daphne Major is a small island in the Galapagos archipelago. A population of finches lives on the island. Finches eat seeds. They use their beaks to crack open the hard outer layer to access the nutritious seed within. What claim does Figure A support? - Beak depth is a heritable trait. - Beak depth is variable in the population. - Beak depth is an adaptive trait. - Finches with deeper beaks survive at higher rates. 14. What claim does Figure B support? - Beak depth is a heritable trait. - Beak depth is determined only by the environment. - Beak depth is an adaptive trait. - Finches with deeper beaks have higher survival.
