One of the major elements of natural selection is that all species have genetic _______.
digression
stability
variation
melanism
2
Which of the following is NOT an example of evolution?
A caterpillar going through a change into a butterfly
Human brains becoming larger over time
All species of tortoises descending from common ancestors
Horses becoming taller and faster over millions of years
3
Genetic diversity is ultimately/mainly the result of
meiosis
reproduction
mutations
viruses
4
Natural selection results in change over time by acting on traits that are
new
mutated
heritable
better
5
An adaptation is
any trait an organism possesses.
how an organism evolves during its own lifetime.
a gene an organism has.
a trait that helps an organism survive in its environment.
6
Individuals that are well adapted to their environment will survive and produce
stronger genes.
fewer mutations.
more offspring.
better traits.
7
Which of the following is NOT a principle of natural selection?
Organisms complete for limited resources
Adaptation allows some organisms to survive and reproduce
Evolution occurs as an organism gets older and learns more
Most species produce more offspring than will reproduce
8
Read the following question carefully:
sexual selection
convergent evolution
natural selection
coevolution
9
Which of the following does NOT increase genetic variation?
Mutations
Mitosis
Crossing over
Gene flow
10
Read the following question about Genetic Variation carefully:
The population will grow quickly.
Some may be resistant and survive.
They will get better at obtaining a food source.
All of the bacteria are already resistant.
11
Genes for traits that help an organism be more successful reproductively can be expected to
become more common in the future.
eventually be eliminated by natural selection.
cause it to evolve into a new species.
cause the extinction of the species.
