Plants and animals that face shared environmental challenges often look very similar, even when they are not closely related and occur in different parts of the planet. This is the result of a process called convergent evolution. Cacti and other succulent plants capable of surviving in very dry environments are great examples of convergent evolution's power, and often look so similar that we frequently misidentify the plants growing in our own homes. In this talk, Professor Richard Glor, curator of Herpetology at the KU Biodiversity Institute & Natural History Museum, and associate professor in the Department of Ecology and Evolutionary Biology, will introduce us to the history, theory, and cosmic implications of convergent evolution. Hosted by Sunflower Outdoor & Bike Shop, 804 Mass.
