Why the Evolutionary Epic Matters
S2 Ep3
9.0
6th Jun 2017
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. An important facet of the story of life is the story of death. This episode will look at the various mass extinctions along the way, and we'll also talk about the sixth mass extinction, which is going on now, and is kind of driven by humans. Sorry everybody.
Why Cosmic Evolution Matters
S2 Ep1
9.0
24th May 2017
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 matter. Today, we're starting with a look at why Cosmic Evolution matters. What exactly does the process of the big bang, the formation of stars, and the birth of planets mean to our lives? Let's find out together.
The Deep Future
S1 Ep10
9.0
9th Jan 2015
Finally, after what seems like eons and eons, the end is nigh. We're talking not only about the end of Crash Course Big History but also the end of everything. The end of humanity and the end of the universe. John and Hank Green will teach you about what the future holds for humanity and the universe. Spoiler alert: in the long, long, long, long, long, long term, it doesn't look good. In the short term though, it's not too bad. But don't lose hope, there is an upside. You'll have to watch the video to find out.
Worst Episodes of Crash Course Big History
The Big Bang
S1 Ep1
6.8
17th Sep 2014
In which John Green, Hank Green, and Emily Graslie teach you about, well, everything. Big History is the history of everything. We're going to start with the Big Bang, take you right through all of history (recorded and otherwise), and even talk a little bit about the future. It is going to be awesome. In the awe-inspiring sense of the word awesome. In this episode, we walk you through the start of everything: The Big Bang. We'll look at how the universe unfolded at its very beginning, and how everything in the universe that we know today came into being. So that's kind of a big deal, right?
Exploring the Universe
S1 Ep2
7.5
24th Sep 2014
In which John Green, Hank Green, and Emily Graslie teach you about what happened in the Universe after the big bang. They'll teach you about cosmic background radiation, how a bunch of hydrogen and helium turned into stars, formed galaxies, created heavy elements, and eventually created planets.
The Sun & The Earth
S1 Ep3
8.0
2nd Oct 2014
In which John Green, Hank Green, and Emily Graslie teach you about our Sun and the formation of the planets. We're going to focus on the formation and development of the Earth because that's where people live. You'll learn about the Solar nebula, the birth of the sun, the formation of planets, and how the Earth and the rest of the solar system developed over the last 4.567 billion years.
Migrations and Intensification
S1 Ep7
8.0
26th Nov 2014
In which Hank and John Green teach you about humanity conquering the Earth. Or at least moving from Africa into the rest of the Earth. As human beings spread out across the world and populations grew, humanity reached a critical mass of innovators, and collective learning took off! All these innovations were great for lots of human endeavors, but none fared better than agriculture.
Life Begins
S1 Ep4
8.3
8th Oct 2014
In which Hank and John Green teach you about life on Earth. They won't be giving advice on how life should be lived, because this is a history series. Instead, they'll teach you about the earliest forms of life on Earth, and some of the ways that they developed into the types of life we know, love, and sometimes don't love so much (I'm looking at you here, opossums). You'll learn about prokaryotes, eukaryotes, panspermia, reproduction, a little about DNA, and even a thing or two about trees. Maybe.

John and Hank teach you about how humans evolved, and the sort of tricks they picked up along the way like complex tool use, big brains, and fighting. Our ancestors adapted to the grasslands of Africa and went through several iterations including Australopithecus, homo habilis, and homo ergaster/erectus. Our ancestors tamed fire, made pressure flake tools, and eventually smartphones.
