California Life Science, Chapter 7: Changes Over Time

So much to do and so little time:

California State Standards covered in the chapter-

• 7.3 Biological evolution accounts for the diversity of species developed through gradual processes over many generations.

1. Students know both genetic variation and environment factors are causes of evolution and diversity of organisms.


2. Students know the reasoning used by Charles Darwin in reaching his conclusions that natural selection is the mechanism of evolution.


3. Students know how independent lines of evidence from geology, fossils, and comparative anatomy provide the bases for the laws of evolution.


4. Students know how to construct a simple branching diagram to classify living groups of organisms by shared derived characteristics and how to expand the diagram to include fossil organisms.


5. Students know that extinction of a species occurs when the environment changes and the adaptive characteristics of a species are insufficient for its survival.
   

• 7.4 Evidence form rocks allows us to understand the evolution of life on Earth.

1. Students know fossils provide evidence of how life and environmental conditions have changed.
