What is a vestigial trait? Explain why the existence of vestigial traits is evidence for evolution via natural selection.

Give a brief example of a situation in which it would be beneficial for an animal to have a relatively high surface area to volume ratio, and explain why having the high surface area to volume ratio is helpful in that situation. (1-2 sentences is sufficient, do not write a long paragraph.)

Natural selection: Camels live in dry, sandy deserts.  They have extremely long eyelashes to keep the sand out of their eyes.  Like you practiced in the “synthesis” portion of Homework #2, provide a logical and detailed explanation of how, across generations, a population of camels with very long eyelashes evolved from an ancestral population with normal-length eyelashes 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 long eyelashes evolved in camels.)

FILL-IN: The scientific name for a lion is “panthera leo”.  Applying the correct conventions of binomial nomenclature, write “panthera leo” in the proper scientific format.  Type carefully and clearly indicate any special formatting required.
