Question

using the drop-down menus, identify the mode of selection explained below. the finches of the galapagos islands changed over time as insects became more smaller and longer beaks were favored. disruptive selection stabilizing selection directional selection

Explanation:

Directional selection occurs when one extreme phenotype is favored over others, leading to a shift in the population's trait distribution. In this case, longer beaks (an extreme trait) were favored as insects became more available, so the finches' beak size changed in one direction. Disruptive selection favors two extreme phenotypes, and stabilizing selection favors the average; neither applies here.

Answer:

directional selection
