Thanks very much to Dr. Dave Ardell, Evolutionary Biologist at UC Merced, SFCS Founding Member, and Parent Volunteer. Dr. Ardell spent time with our 7th and 8th graders this week, discussing blood in general, population genetics, sickle cell anemia, and natural selection. His demonstration included a cool game using cards and dice to show how natural selection works. Students had studied adaptation, natural selection and evolution in the winter making this a great expansion of some topics they had touched upon. Students also enjoyed hearing about Dr. Ardell's classes and students at UC Merced.
