ESSAY: NATURAL SELECTION Tarsiers are a kind of primate. They have the largest eyes relative to body size of any mammal — each eyeball is as large as their brain! Tarsiers are active only during the night, and their huge eyes are an adaptation for this nocturnal lifestyle.   Like you practiced in the “synthesis” portion of Homework #2, provide a logical and detailed explanation of how, across generations, a population of tarsiers with extremely large eyes evolved from an ancestral population with normal-sized eyes due to the process of natural selection.  Apply and define relevant vocabulary.   [Note: Unlike in Homework #2, here you do not need to list the 4 criteria first, just provide the “synthesis” part of the explanation. Your explanation should be clear, complete, and logical so that someone who does not already understand natural selection would be able to understand the process by which huge eyes evolved in tarsiers.)
