Ch 17 & 19.2 Patterns of Evolution
LS-E14. Relate diversity and adaptation to structures and their functions in living organisms (e.g., adaptive
radiation).
LS-H20. Recognize that a change in gene frequency (genetic composition) in a population over time is a
foundation of biological evolution.
LS-I24. Analyze how natural selection and other evolutionary mechanisms (e.g., genetic drift, immigration,
emigration, mutation) and their consequences provide a scientific explanation for the diversity and unity
of past life forms, as depicted in the fossil record, and present life forms.
We will be taking what we learned in the last unit about how evolution works and
applying it to entire populations…what things make an entire population different over
time? This is called macroevolution and involves what you learned about genetics in ch 11,
as well as what you learned about evolution in ch 16.
At the end of the unit, you will have a mixed format (multiple choice, short answer,
diagrams…) test over the material.
