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.

What is the difference between a theory and
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.

2. The same agent of natural selection works on both
sexes.
3. Different agents of natural selection work on the two
sexes.
4. Natural selection has influenced only the males, not
the females.
