(D) What is coevolution and why does it happen?
(E) Sometimes predator and prey populations oscillate/cycle in synchrony with each other. Explain why this happens.

· convergent evolution
· punctuated equilibrium
· natural selection
· gradualism
Sled dogs have a thick coat of hair that helps them withstand the cold temperatures of the Arctic. Compare that adaption to a single, unrelated dog that grows a thicker coat in the fall in response to colder temperatures. The adaptation of the sled dog best describes adaptation at the ____________ level while the dog exposed to seasonal colder temperatures has _____________.
Multiple Choice
· regional; natural selection at the individual level
· individual; physiological modifications at the population level
· population; physiological modifications at the individual level
· species; natural selection at the population level
