Today’s pod has Dr. Jackson Njau, a paleoanthropologist working to understand how early humans evolved and why. Hear about his work in Olduvai Gorge in Tanzania, how our brains have grown over time (as hard as that may be to believe for some people), and a favorite dish of his family - Ndizi.

A new episode of the pod has just released featuring Dr. Travis O'Brien. Hear about the mystery behind climate models and supercomputers, his time at a national lab, and, perhaps most delightfully surprising, his time living on an alpaca ranch. geologyontherocks.transistor.fm/episodes/sup...

We are new here but hope to reach more people with our podcast, Earth on the Rocks, a show were we get to know the person behind the science. Each episode will highlight a new scientist in the earth and atmospheric sciences: geologyontherocks.transistor.fm
