Standard 8b Preknowledge
8b) Students know a great diversity of species increases the chance that at least some organisms survive major changes in the environment.
CALIFORNIA FRAMEWORKS SUMMARY:
This standard is similar to the previous standard set on diversity within a species but takes student understanding one step further by addressing diversity among and between species. For the same reasons pertinent to those for intraspecies diversity, increased diversity among species increases the chances that some species will adapt to survive future environmental changes.
