Over time, the climate of an island became drier, which resulted in changes to the populations of various island finch species. Finch populations with a certain beak shape thrived, while those not having that beak shape decreased. Which of the following describes a necessary condition for these changes in the finch populations to occur?

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	Limited food resources.
B	Fewer mutations.
C	Limited beak variations.
D	Overproduction of offspring.

Explanation:

Detailed explanation-1: -Finch populations with a certain beak shape thrived, while those not having that beak shape decreased. Which of the following describes a necessary condition for these changes in the finch populations to occur? Limited resources are a major driving factor for natural selection.

Detailed explanation-2: -Which of these evolutionary mechanisms primarily resulted in the evolution of medium ground finches on the island of Daphne Major? Natural selection.

Detailed explanation-3: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’

Detailed explanation-4: -Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
