Darwin theorized that individuals having an advantage due to their traits or abilities will be more likely to survive and reproduce.  This theory is known as

• speciation

• adaptation

• natural selection

Charles Darwin’s observation that finches of different species on the Galápagos Islands have many similar physical characteristics supports the hypothesis that these finches

• have the ability to interbreed.
  have the ability to interbreed.

• acquired traits through use and disuse.

• all eat the same type of food.

• descended from a common ancestor.

What series of islands off the coast of South America did Darwin spend considerable amount of time and greatly influence Darwin's work.

• Hawaiian Islands

• Galapagos Islands

Darwin found the following finches on the Galapagos islands. What best describes why they have different beaks?

• Genetic variation has made it possible for birds to feed on different forms of food due to their beak shape.

• Genetic variation has made it possible for larger eyes on the birds to see.

• Genetic variation has made it possible for the birds to camouflage themselves on the island.

• Genetic has made it possible for the birds to feed at different times of the day due to competition.

Cats, dogs, humans, wales, birds and bats all have the same bones in their arms, wings and fins. How do we use this to support the "Theory of Evolution?"

• Evidence they evolved from a common ancestor.

• Evidence they evolved separately from each other.

• Evidence they all evolved on different continents.

• Evidence they all came from the same mom.

What is survival of the fittest?

• It is where the fittest die out and therefore reproduce and pass on their genes

• It is where the fittest die out and therefore can't reproduce and pass on their genes

• It is where the fittest don't die out and therefore can't reproduce and pass on their genes

• It is where the fittest don't die out and therefore reproduce and pass on their genes
