Nаturаl selectiоn: Cаmels live in dry, sandy deserts.  They have extremely lоng eyelashes tо 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, natural selection caused a population of camels with very long eyelashes to evolve from an ancestral population of camels with normal-length eyelashes.  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. Tell me the story of how and why extra-long eyelashes evolved in camels. Your explanation should be clear, complete, and logical so that someone who does not already understand natural selection would be able to easily understand the process by which long eyelashes evolved in camels.]
