About the course

In this class, we’ll learn about how natural selection works through activities and real examples. We’ll get some hands-on practice to see how an animal’s features can affect its survival, and talk about why that’s important. We’ll end by thinking about the fascinating questions scientists are still asking today about natural selection and evolution.

Hello! My name is Sofia and I am a recent graduate of Columbia University, where I studied evolutionary biology. After graduation, I spent almost a year in Costa Rica doing behavioral field work with white faced capuchin monkeys. I am currently completing my Master’s in Teaching at New York University while working as a middle school science teacher. Previously, I have also done field work in Kenya and worked at the American Museum of Natural History.
