The longnose butterfly fish has a dark spot near its tail that looks like an eye. Its "eyespot" makes predators think they are attacking the head rather than the tail. Why does the longnose butterfly fish have an evolutionary advantage over other fish?

• It is more effective at finding mates than other fish.

• It is more effective at catching shrimp and worms than other fish.

• It is likely to produce more offspring that survive to maturity.

• It uses less energy to swim than other fish.

If scientists were to compare the fossil of a fern that lived millions of years ago with other fern fossils that were formed later, what would they most likely find?

• that plants had bones millions of years ago

• that plants change over time

• that ferns stopped evolving 25 million years ago

• that only animals evolve

How would a warming climate affect the species in an ecosystem?

• individuals might die off but a species cannot disappear completely

• species would increase in number to offset the numbers killed by the heat

• species that have never been seen before would suddenly appear

• individuals best able to survive the heat would become more likely to reproduce

Occasionally a mutation produces a bird with a new characteristic. What determines whether this bird will be the beginning of a new species?

• The bird must dominate the other birds and reduce their ability to reproduce

• The bird must be able to live in the usual environment for that fish

• The mutation must provide some type of advantage for the bird

• The mutation must make the bird very different from other fish

How have 340 breeds of dogs emerged from wolves?

• natural selection has allowed the toughest dogs to survive

• humans have selectively bred dogs for desired traits

• wolves have a diverse gene pool that contains many variations
