Exercise 22

"Survival of the fittest" may be a misleading phrase to describe the process of evolution by natural selection, because:
A) it is impossible to determine the fittest individuals in nature.
B) survival matters less to natural selection than does reproductive success.
C) natural variation in a population is generally too great to be influenced by differential survival.
D) during population bottlenecks, it is the least fit individuals that have the greatest survival.
E) reproductive success on its own does not necessarily guarantee evolution.
