7C Natural Selection

The more genetic variation a population has,

the more likely it is for some individuals to

• evolve

• migrate

• survive

• mutate

Why do frogs and other organism reproduce so many eggs or offspring?

• so that their babies can have friends to play with
• the more offspring the more likely the offspring will survive
• the more offspring the less likely offspring will survive 
• the more offspring the less competition

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

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

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

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 
• No, they change because of natural selection

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

• Selective Breeding

The long and sharp beak of a woodpecker is an example of:

• Natural Selection
• Selective Breeding

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• changes in genotype, but not phenotype
