In the 1860s, Charles Darwin proposed the theory of evolution. His theory stated that populations change very
slowly over a very long period of time. Then in 1972, some
scientists took a closer look at the fossil record. They
concluded that evolution involves long periods of little
change in populations which are interrupted by short
periods of rapid change. This finding became part of the
theory of evolution. What can you conclude from this
information?
a. New evidence can cause a scientific theory to be
modified.
b. New evidence can cause a scientific theory to be
discarded.
c. New evidence can cause a scientific theory to become a
law.
d. New evidence can cause a scientific theory to change
into a new theory.
