If a mutation occurs in one member of a
population, does that constitute evolution?
1. Yes. Any change in an individual always
results in evolution of the entire population.
2. Yes. Mutations always encode for favorable
traits.
3. No. Mutations always lead to death.
4. No. Evolution is a product of change in the
population, not in the individual.

How would Darwin have determined whether the
Patagonian hare from Ecuador and lop-eared
rabbits from England were the same species? He
would have:
1. Looked at both types. If they look alike as
adults, then they are the same species.
2. Compared their behaviors to see whether
they are the same in different environments.
3. Bred them to see whether they could
produce fertile offspring.
4. Seen whether they occupy the same niche
within different environments.

What is the difference between a theory and a
hypothesis?
1. A theory is widely supported by scientific
evidence; a hypothesis is an educated guess
that can be disproved.
2. A hypothesis cannot be disproved; a theory
is an educated guess.
3. A theory is true; a hypothesis is false.
4. A hypothesis is true; a theory is false.
