Question

A) Which major event led to the eventual adaptive radiation of Darwin’s finches from one common
ancestor (i.e., what is the primary reason they evolved)? (1 point)
different predators
differing availability and types of food resources
drought
increased rainfall

Answer 1

The primary reason for the adaptive radiation of Darwin's finches from one common ancestor is **differing availability and types of food resources**. This variation in food sources led to the evolution of different finch species with specialized beak shapes and sizes to exploit those resources. While events like drought and increased rainfall can impact food availability temporarily, the main driver of their adaptive radiation is the diversity of food resources available on the islands.
