- 1. Multiple Choice
A population evolves when
a decision is made.
a selective pressure changes the gene distribution of the population over time.
it grows more fingers, as needed.
it sticks to the plan.
- 2. Multiple Choice
What do scientists mean when they use the term 'theory'?
A theory is a hunch or a guess.
A theory is a collection of fictional stories that, when added together, help shape the view of the natural world.
Theories are ideas that explain natural phenomena.
A theory just is an unproven law.
- 3. Multiple Choice
The fossil record suggests
species never change.
dinosaurs are not real.
evolution did not occur in the time of the dinosaurs but picked up later in Earth's history.
species change over time.
- 4. Multiple Choice
The hind leg bone structures found in the skeletons of modern whales are examples of vestigial organs. Which of the following statements is true?
Leg bones in whales are not proof of evolution.
The most recent common ancestor of every species of whale did not have leg bones.
The presence of leg bones in whales suggest whales evolved from a four-legged common ancestor.
The leg bone structures will evolve into new fins someday.
- 5. Multiple Choice
The bones found in a human hand and a bat's wing are examples of homologous structures. Which statement about the bones in a human hand and bat wing is true?
The bones suggest humans and bats share a common ancestor.
The bones might allow humans to fly and bats to write.
The bones are formed from homozygous recessive genes.
Homologous structures are the same as vestigial organs.
- 6. Multiple Choice
What do all living things on Earth have in common?
All species have homologous structures where hands are found.
All species use RNA or DNA to carry their genetic informaiton.
All species have some version of an appendix, a vestigial organ found in humans.
All species photosynthesize or can evolve the ability to photosynthesize.
- 7. Multiple Choice
Similarities between human genomes and those of other species like the chimpanzee, mouse, or fruit fly suggest
every species' genome is about 96% similar.
DNA will evolve into RNA.
humans share a common ancestor with chimpanzees, mice, and fruit flies.
humans evolved from chimpanzees, mice, and fruit flies.
- 8. Multiple Choice
Darwin's finches are characterized by different sized beaks, the phenotypes of which were caused by different selective pressures like access to certain types of food. Darwin theorized that the finches
evolved because they wanted to.
evolved through unnatural selection.
with medium-sized beaks are best adapted because nature tends to favor 'average' phenotypes.
all share a common ancestor.
- 9. Multiple Choice
Insect species can develop genetic resistance to pesticides like DDT over time. Which of the following statements is FALSE?
Insecticide resistance is an example of evolution.
The insecticide-resistance gene allows parents to survive long enough to pass it on to its offspring.
Over time, the gene for insecticide resistance will increase in frequency among the gene pool.
Insects are able to make a decision whether or not they want to adapt to the insecticide.
