Natural Selection

Why do peppered moths tend to be the same color as the trees on which they live?

• The coloring goes along with tasting like the tree. 
• It keeps the moth the same temperature as the tree. 
• It makes the moths faster than the birds
• It makes the moths harder to see.

Which of these is an example of natural selection?

• The largest animal in a population will have more opportunities for reproduction.
• Several species of organisms work together so that they all succeed.
• One species takes all the resources in an environment leaving none for others.
• Organism that are best suited to an environment tend to survive and reproduce more often.

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.

Darwin studied which of these species on Galapagos?

• Pigeons and tortoises
• Tortoises and finches
• Finches and Pigeons
• Zebras and Mockingbirds

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

Survival of the Fittest and Evolution were proposed by what scientist?

• Charles Darwin
• Albert Einstein
• Steven Hawking
• Isaac Newton

• biological evolution
• transition
• variation
• adaptation

When an organism has a trait that allows it to blend in with its environment, we call that ____.

• mimicry

Before the invention of the light bulb, Americans burned oil in lamps for light. Whale oil was popular bio-fuel for these

lamps. Ship crews would hunt whales for their oil. They searched for the largest whales they could find so that they could obtain as much whale oil as possible. How mighty decades of whale hunting possibly affect the natural selection of the species?

• The whales lost their legs.

• The whales became slower.

• The whales became smaller.

• The whales changed their calls.
