Correlate evolutionary theories and
processes
• Biological
 Students
will be able to explain evolution
and describe the evidence that exists
that supports the theory of evolution.
A
scientific theory is a way to
EXPLAIN observations and scientific
findings.
• Examples: geocentric theory, evolution,
general relativity, cell theory
The
theory of
evolution is the
idea that there has
been gradual
change in living
things over long
periods of time.
The
fossil record
shows what life has
been on Earth and
how that life has
changed.
• Many organisms
have evolved and
many have gone
extinct.
Natural
selection is the idea that
traits that are beneficial to a species
survival will become more
widespread.
Example: If giraffes
want to survive,
they must have
longer necks to
reach higher into
trees to get food.
