Birds are eating all the green beetles. Because the brown beetles are surviving they reproduce more and make more brown beetles. This is called ___________

• Artificial Selection

• The Theory on the Origin of Species

• Natural Selection

• Mutation

If scientists find fossils of a type of mosquito on the bottom layer and find fossils of beetles towards the top layer, what can scientists infer?

• Mosquitos ate the beetles

• Mosquitos are older fossils than beetles

• Beetles are older fossils than mosquitos

• Both mosquitos and Beetles must have lived at the same time.

• Once animals are adapted to eating something they never change their diet

• The traits of animals can be understood in relation to their environment

Some species survive and some die out. The ones that survive probably...

• interbreed with other species

• inherit some advantageous variations

• are attacked by more predators

One species of birds became 2 species when separated by a mountain. This happened because...

• one species had higher mutation rates

• the original species had a lot of genetic divesity

• one species reproduced more quickly than the other

• there was isolation of the two groups

Finding fossils of coral reefs in the Nevada desert provides evidence that

• Nevada used to be much colder than it is today

• An ocean once covered what is now Nevada

• Ancient corals used to live on land

• There was a mistake because no coral reefs exist in deserts

If the embryos of different species look similar, this shows...

• no evolutionary relationships between the groups

• recent common ancestry

• evolution from a distant common ancestor

• similar environments in the past

Remember the light and dark moths? If there were a lot of light moths, but then the dark moths started to increase, which could be true?

• natural selection quickly changes the allele frequencies in a population

• predators prefer to eat the light moths

• the dark moths are physically superior to the light moths

• natural selection creates irreversible changes
