Natural Selection, & Evolution--Evidence of Change
3. Biological evolution accounts for the diversity of species developed through gradual processes over many generations. As a basis for understanding this concept:
a. Students know both genetic variation and environmental factors are causes of evolution and
diversity of organisms.
b. Students know the reasoning used by Charles Darwin in reaching his conclusion that natural
selection is the mechanism of evolution.
c. Students know how independent lines of evidence from geology, fossils, and comparative
anatomy provide the bases for the theory of evolution.
e. Students know that extinction of a species occurs when the
environment changes and that
the adaptive characteristics of a species are insufficient for its survival.
