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 were able to forage for food. The population of those not having that beak
shape decreased. Which of the following describes a necessary condition for these
changes in the finch populations to occur?
O fewer mutations
O limited resources
limited beak variations
underproduction of offspring

Because of the difference in the genetic makeup of those with the beak shape, their population evolves to a higher level of adaptation. I think it should be fewer mutated.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
