- Bigger, Stronger, Faster: Dinosaurs and the Evolutionary Arms Race

The natural world can be a very dangerous place, especially living in an evolving planet 66 to 220 million years ago. Over a period of nearly 160 million years, dinosaurs evolved from relatively small omnivores to fast carnivores with bigger, sharper teeth and claws and tremendous bite strength and to herbivores with defenses of more and bigger horns and spikes, thicker armor, and incredible size. Other survivor adaptations including behavior, camouflage coloration and intelligence are inferred from recent scientific discoveries. Other creatures which evolved and competed with the dinosaurs grew to incredible sizes and ornate skeletal features which are still topics of much discussion. This class will examine many of these evolutionary changes that may or may not have been beneficial.
This class from OLLI at the University of Arizona will be recorded. OLLI-UA recordings can take up to a week after the class meeting to become available.

We'll explore Upper and Lower Bidwell Park, Indian Fishery, and the Genetic Resource & Conservation Center (Chico Tree Farm). Participants provide their own art materials and choose their subjects.

- The Aging Eye
-
Our eyes exhibit age-related changes in performance as we get older, particularly as we reach our 60s. Some of these changes are perfectly normal and don't signify any sort of disease process. And though cataracts can be considered an age-related disease, they are common in older adults and can be readily corrected with surgery. Benjamin Gilbert and other doctors from OLLI sponsor Chico Eye Center explore these common changes, as well as more serious age-related eye diseases. Understanding more about our aging eyes and what we can do as we notice changes can help improve our eye health and overall quality of life.
This class meets April 22, May 6, May 20, and June 10.
