Natural Selection-Pre AP

How do you "win" at natural selection?

• survive

• go extinct

• survive & reproduce

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

• Dark moth
• Light moth
• Both will be equally successful
• Neither will be successful

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

These moths are all the same species. The differences between their wings is an example of
(a)  

• Variation
• Natural Selection
• Homeostasis
• Extinction

When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called

• evolution by natural selection
• artificial selection
• inbreeding
• outbreeding

Which of the following explains adaptation.

• An individual organism changes to meet its needs in the environment. These changes pass down to their offspring.
• The species as a whole changes their characteristics.
• Beneficial traits allow organism to survive and pass on those traits
• New characteristics arise in a species as needed.  If these traits are helpful, they are passed down.

When an environment changes faster that an species can adapt, the most likely outcome is...

• ...biological evolution.
• ...voluntary mutation
• ...species extinction
• ...selective breeding

Evolution works by 

• individuals changing to suit their environment
• Individuals learned new traits and pass them on
• sudden change in the environment cause a species change 
• small changes pass down through many generations

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
• Hardey-Weinberg equilibrium within a population
