The tools made by our human ancestors may not seem like much when you compare them to the screen you’re looking at right now but their creation represents a pivotal moment in the origin of technology and in the evolution of our lineage.

Thanks to Fabrizio De Rossi, Julio Lacerda and everyone else at Studio 252mya for their excellent hominin illustrations. You can find more of their work here: https://252mya.com/
