Gregor Mendel was the first scientist to use statistics to analyze scientific data. Before Mendel’s experiments, scientists believed that organisms acquired traits from their environment and passed them on to their offspring. After Mendel’s discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. This is an example of
Answer
A
a theory changing because a new scientific method was developed.
B
a law changing because a new scientific method was developed.
C
a hypothesis changing because a new scientific method was developed.
D
an observation changing because a new scientific method was developed.
Explanation
Mendel’s use of statistics was a new scientific method that helped scientists analyze inheritance more carefully. The evidence from his experiments changed the accepted explanation of how traits are passed to offspring, from traits acquired from the environment to genes passed from parents. That is a theory changing because a new scientific method was developed; it is not a law, hypothesis, or single observation changing.
