Public lecture on evolution followed by Darwin birthday party. Lecture by Len Eisenberg, geologist, founder of Evogeneao.com, and builder of earth history parks and geologic climbing walls. Talk will describe how life on Earth is one big extended family, with all life forms related by common descent, and natural selection as the primary driver of evolutionary change. The overwhelming evidence for evolution is presented with humorous cartoons as rebuttals to common arguments against evolution. Birthday party after the talk features refreshments and birthday cake. Attendees wearing full or partial animal or plant costume get a free Evogeneao evolution tee shirt, and best costumes get an Evogeneao evolution hoodie.
