Humans have evolved over the course of several million years since our common ancestor with chimpanzees, and in that time many different species of ancient human have walked the earth. In this course we will take a deep dive into the fossil record to learn about these species, and the series of remarkable adaptations in our lineage that resulted in modern humans. In so doing, you will learn about the ancient environments our ancestors inhabited, their diet and anatomy, and the evolutionary processes that led to our unique form bipedal walking and running, as well as our enormous and complex brains. This course will consist of lectures and group discussions, as well as in-class activities where you will examine castes of ancient human fossils. This course is dual-listed with APY 461.
