According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce?
a)
Some individuals pass on to their offspring new characteristics they have acquired during their lifetimes.
b)
Some individuals are better adapted to exist in their environment than others are.
c)
Some individuals do not pass on to their offspring new characteristics they have acquired during their lifetimes.
d)
Some individuals tend to produce fewer offspring than others in the same environment.
