Tracing our evolutionary journey through anthropology
Biological anthropology reveals the deep story of human origins—from our primate ancestors to the remarkable diversity of modern humans. This hub explores how we became human through the lens of evolution, where variation itself is the ground condition of life. Through an anthropological perspective, we examine the science of human origins while challenging harmful myths about race and human difference. Discover how the 99.9% genetic similarity among all humans coexists with our visible diversity, and learn what our evolutionary journey through Ice Age challenges reveals about resilience, adaptation, and the ongoing process of human variation.
Variation as the Ground Condition of Life
Human variation reveals our fundamental paradox: we are 99.9% genetically similar yet remarkably diverse. This makes sense once we abandon the Great Chain of Being and recognize that variation is the “ground condition of life”—not a ladder to climb but the very basis of evolution itself. The Ice Age demonstrates this perfectly, showing diverse human groups engaged in “mosaic evolution,” interbreeding with Neanderthals and Denisovans while adapting to varied environments through both biological flexibility and niche construction.
Why do humans look different if we’re 99.9% genetically the same? My most recent reflections are from Intro to Anthro 2025 using The Human Story as a textbook
Evolution depends on variation and diversity. For a 2021 course in a series that also includes one of my most-watched lectures, “Is Evolution a Myth?”
