Evolution as something you can watch: what a scientific theory is, natural selection in the peppered moth, bacteria evolving in flasks since 1988, Darwin's finches measured, our common ancestor with chimpanzees, milk and recent human evolution, antibiotic resistance and breeding (and how to explain it clearly) from the National Academies and the research.

AT THE SUMMIT, YOU WILL BE ABLE TO

01Explain what a scientific theory is, and why evolution is one

02Describe natural selection with real, measured examples

03Fix the common myths about evolution and human origins

04Connect evolution to antibiotics, breeding and your own DNA
