Evolution Review

What did Charles Darwin observe that gave him the idea of evolution?

• google
• wikipedia
• mans attempt to destroy mankind
• finches in the Galapagos island

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.

1. The process of choosing parent organisms for desired characteristics is called

• natural selection

• Artificial selection

• random selection

• genetic manipulation

What is an example of artificial selection?

• Letting dogs choose their own mate

• Letting plants pollinate on their own

• Crossing a labrador and a poodle to create a labradoodle

The phrase "Survival of the Fittest" would best describe...

• Natural Selection 
• Artificial Selection 
• Selective Breeding
• Rainbow Trout

How does natural selection drive evolution?

• It does not; natural selection and evolution are entirely separate processes

• Before they can reproduce, individuals must adapt certain traits through natural selection.

• Within a generation, natural selection causes populations to eliminate unfavorable traits.

• Over time, natural selection causes living populations to evolve environmental adaptations.
