MODEL CURRICULUM (GRADE 8) Life Science

TOPIC- Species and Reproduction

CONTENT STATEMENT- Diversity of species occurs through gradual processes over many generations.  Fossil records provide evidence that changes have occurred in number and types of species.

GRADE 8 CONCEPTSS- The sorting and combinations of genes results in different genetic combinations, which allow offspring to be similar to, yet different from their parents and each other.  These variations may allow for survival of individuals when the environment changes.  Diversity in a species increases the likelihood that some individuals will have characteristics suitable to survive under changed conditions.
