>>8.4.2 Historical and Scientific Research. Superintendents, historians, scientists,
and interpretive staff are responsible for ensuring that park interpretive and
educational programs and media are accurate and reflect current
scholarship…Questions often arise round the presentation of geological,
biological, and evolutionary processes. The interpretive and educational treatment
used to explain the natural processes and history of the Earth must be based on
the best scientific evidence available, as found in scholarly sources that have
stood the test of scientific peer review and criticism. The facts, theories, and
interpretations to be used will reflect the thinking of the scientific community in
such fields as biology, geology, physics, astronomy, chemistry, and paleontology.
Interpretive and educational programs must refrain from appearing to
endorse religious beliefs explaining natural processes. Programs, however,
may acknowledge or explain other explanations of natural processes and events.
