Natural Selection

Adaptations can be:

• camouflage

• ability to survive cold weather

• hunting skills

• all of the above

A yellow morph and green morph of an insect lives in the rainforest canopy. You would expect:

• the green population to increase and the yellow to decrease

• both populations should stay the same

• both populations will increase

• the green population to decrease and the yellow to increaseThis is a wrong answer

How do you "win" at natural selection?

• survive

• go extinct

• survive & reproduce

When every organism of a species has died.

• Evolution
• Natural Selection
• Extinction
• Artificial Selection

Natural Selection is driven by a change in the environment and survival of the

• Earth

• Fastest

• Fittest

• Biggest

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the organism knew it needed that trait, survives, and passes it on.

The differences among a species, like different bird beaks, are called

• genes.
• variations.
• traits.
• theories.

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

What process is being shown in this image?

• Variation
• Natural Selection
• Selective Breeding
• Homeostasis

Where do adaptations come from?

• The individual organism decides to adapt

• Mutations that give an organism an advantage in its environment

• Genetic recombination during meiosis

• Both mutations and genetic recombination are sources of adaptation
