10 Species of the Genus Homo. What Makes Us Human? Exploring what defines the Genus.

In this episode of Dry Bones: Faith and Archaeology in Conversation, I (M.A. Anthropology, Archaeology emphasis) unpack how scientists classify the genus Homo—from Homo habilis to Homo sapiens. Discover what sets us apart from other ancient hominins like Australopithecus, the traits of many species of Genus Homo and why these scientific definitions still connect to our biggest spiritual questions about identity, consciousness, and being made in the image of God.

You’ll learn:

How archaeologists and anthropologists define Homo

What traits (like brain size, tool use, and bipedalism) make us uniquely human

Why some species like Homo naledi blur the lines between human and pre-human

The fascinating process of how species get classified — and why scientists still debate it

The wide mosaic of traits that species of the Genus Homo display

Whether you’re drawn to faith, science, or the intersection of both, this deep dive gives you the foundation for understanding humanity’s story from the ground up.
