Crash Course: Big History 2

Crash Course Big History is back! It turns out, we couldn't tell all of the 13.8 billion years of the history of the universe in 10 Crash Course Episodes. So, Big History host Emily Graslie has returned to add 6 more episodes that look at why the stuff we studied in Big History matters.

So, the stars made the elements, we're all made of star stuff, etc. But what does all this mean? This week Emily Graslie teaches you how the formation of chemical elements in the bellies of the earliest stars made life as we know it possible.

Today we're talking about evolution?basically the history of all life on Earth. The thing is, why are we talking about this. Well, the story of life, all the way back to single-celled microbes billions of years ago, is all part of our human story.

This week on Crash Course Big History, Emily is talking about the process of human evolution, and the knack for innovation that has allowed humans to become so dominant on the Earth.

This week, Emily Graslie is teaching you about human ancestry and genealogy, how we got to be the species we are, and why that matters in our zoomed-out look at Big History.
