Evolution objectives
Students should be able to…1. Describe what the Theory of Evolution states.2. Name the person who developed this theory and describe how he
developed it.3. Define the following and give an example of each.
SpeciesPopulationNatural selection
4. Describe how fossils and strata provide evidence for the theory of evolution. 5. Determine the age of rocks and fossils using radioactive dating.6. Describe an example of homologous structures.7. Determine allele frequencies.8. Describe what the Hardy-Weinberg (H-W) principle /law/ theory states and be sure to list the 5 H-W conditions.

Theory of Evolution HypothesisIFIF
populations populations accumulate accumulate change over change over timetime
THEN THEN species that species that look similar look similar should have should have close common close common ancestorsancestors

Homologous Structures
- Look similar, but…- Look similar, but…-the structures have different mature forms in the structures have different mature forms in different organisms, different organisms, -develop from the same embryonic tissuedevelop from the same embryonic tissue
- do not necessarily have the same function- do not necessarily have the same function
