Let's imagine the worst scenario for civilization: humans, for one reason or another, go extinct. What will rise from the ashes of the Anthropocene to take their place? In the second part of this two-part series, Ben, Matt and Dylan explore the possible candidates, from various high-order mammals and avians, to life beneath the seas, to plants, fungi, artificial intelligence and more. (We're extremely excited about this one, and can't wait to hear your picks for the next rulers of Earth.)

Humans! Seems like they're everywhere these days. They've also been great for our show, so thanks! Anyhow, the Age of the Anthropocene has fundamentally altered the natural world -- and, no matter what happens, the legacy of the human will remain long after the actual species is gone. What happens when the humans are no more? In the first part of this special two-part series, Ben, Matt and Dylan explore the still-controversial origin of Homo sapiens, along with how the world might look when Earth's favorite superape no longer rules the roost.
