Which of these scenarios is an example of natural selection?

• Farmers crossbreed two types of cows to produce a breed of cow that has high-quality beef and can tolerate a hot climate.

• 
  Giraffes that have longer necks survive a dry season by eating leaves from the tops of trees. Those giraffes breed more successfully that year.

• Dogs of the same breed that have a desirable coat color are bred with one another to produce more puppies with that same coat color.

• Rattlesnakes that rattle when approached by humans are killed, but rattlesnakes that remain silent are not killed. The quiet snakes survive and breed.

When two species have structures that are very similar physically, it shows that the species may have evolved from a common ancestor that also had a similar structure, which provides evidence that the species are related. This statement explains that similar skeletal structures but have different functions provides evidence of...

Mr. Van listed four topics on the board.

1. 1. relationships between extinct and living organisms

2. 2. which ancient species are the ancestors of modern-day species

3. 3. how groups of species may be related by age and physical characteristics

4. 4. complete genetic similarities and differences between modern-day organisms

For which of these topics does the fossil record provide evidence?

• 1 only

• 1 and 2

• 1, 2, and 3

• 1, 2, 3, and 4
