-->
1.  adaptation
Definition: A body structure or behavior that gives an organism a better chance of surviving and reproducing in its environment
Context: Charles Darwin observed different kinds of beaks on finches, which was an adaptation that enabled finches to survive in their environments with minimal competition for food.

2.  Charles Darwin
Definition: A British scientist who developed the theory of evolution in the 19thcentury
Context: After observing the tremendous variety of life forms on the Galapagos Islands, Charles Darwin developed his theory of evolution.

3.  Intelligent design
Definition: An idea that has emerged in the 21stcentury that states that the variety of life-forms on Earth could not have developed without a spiritual force with a preconceived idea of what life should look like
Context: The reason many scientists object to having intelligent design taught in science class is that it is not a scientific theory, which is based on observations and experiments that can be replicated over time.

4.  natural selection
Definition: The process through which life-forms best suited to a particular environment survive and reproduce, while those less suited to a given environment die out
Context: According to Darwin, natural selection is set in motion by the fact that the world is a cruel place and can support only those creatures that are the strongest and best able to survive.

5.  scientific theory
Definition: Ideas that are based on observations and experiments that can be replicated by others and have held up over time
Context: Evolution is considered by many to be one of the best-supported scientific theories ever developed.

6.  Scopes trial
Definition: The 1925 trial between John Scopes and the state of Tennessee in which Scopes was tried for teaching evolution in his science classroom in violation of a recently passed law that forbade the teaching of any interpretation of the beginning of life other than the one found in the Bible
Context: During the Scopes trial, Clarence Darrow presented a powerful defense of John Scopes' actions; nonetheless, Scopes was still found guilty of violating Tennessee law.

7.  theory of evolution
Definition: Charles Darwin's theory about the development of diverse life-forms based on the premises that all life developed from a few very simple organisms and that natural selection is the mechanism that caused these changes to take place
Context: Although the theory of evolution is based on a great deal of scientific evidence, it continues to evoke debate.
