Scientists observed a population of monkeys on an island. The monkeys were observed to have different finger lengths. Some monkeys had long fingers, some had short fingers, but the majority of them had finger lengths that were closer to the short finger length. Explain how this trait in the population of monkeys would evolve over time if tree branches on the island grew thicker. Would this be an example of stabilizing, directional, or disruptive selection?

They would all have longer fingers to grasp the thicker branches, directional.

Explanation:

To grasp a thicker branch, you’ll need longer fingers. Directional selection favors one extreme phenotype (physical trait), while disruptive selection favors both extremes and stabilizing favors neither extreme. Hope it helps :)

cramming before a final is bad because it makes a student's stress level higher. students who embrace cramming to get through a final exam week find themselves struggling to perform consistently, once the brain adjusts to prolonged sleep deprivation.
