The Living Environment: Evolution of Life
Grades 6-8, page 124
Small differences between parents and offspring can accumulate (through
selective breeding) in successive generations so that descendants are very
different from their ancestors.
NSES Content Standard C
Life Science: Regulation and behavior
Grades 5-8, page 157
An organism's behavior evolves through adaptation to its environment.
How a species moves, obtains food, reproduces, and responds to danger are
based in the species' evolutionary history.

Life Science: Diversity and adaptations of organisms
Grades 5-8, page 158
Biological evolution accounts for the diversity of species developed
through gradual processes over many generations. Species acquire many of
their unique characteristics through biological adaptation, which involves
the selection of naturally occurring variations in populations. Biological
adaptations include changes in structures, behaviors, or physiology that
enhance survival and reproductive success in a particular environment.
