Evolution Review

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

• evolution
• speciation
• adaptation
• natural selection

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

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.

The white feathers of a snowy owl allow it to blend in with its environment during the winter months (snow). This is an example of ________________

• Adaptation
• Variation

Darwin referred to this as survival of the fittest. Over time, it results in changes in the inherited characteristics of a population because organisms with adaptations that make them fit for their environment will survive and reproduce better than those without favorable traits.

• Natural Selection
• Genetic Variation
• Survival of the Fittest
