Hey Vox, Conversations listeners, it's Sean Eileen. We've got something a little different for you today.

We're going to play an episode of a new show from our colleagues at Vox that we think you will really

dig. The show is called Unexplainable and it's all about the most fascinating mysteries in science.

Each week the team will dive into one question in science that remains unanswered and talk to

scientists and experts about how they try to find answers to these questions. Unexplainable is

hosted by Nome Hasenfeld and will feature reporting from producer Bird Pinkerton and Vox

Science reporter Brian Resnick. This episode is called Skeleton Lake and it tells the story of

a group of scientists examining the DNA of ancient bones found near Himalayan Lake and the seemingly

impossible conclusion they landed on. Next week's episode tells the story of why mysterious balls

of lightning, yes, balls of lightning, have been recorded throughout history. You will not want to

miss it. Talking about what we don't know can be uncomfortable but right now it's more important

than ever before. You can follow Unexplainable in your favorite podcast app to get new episodes every

Wednesday morning.

This is Unexplainable. I'm Nome Hasenfeld. For most of human history, which goes back hundreds of

thousands of years, our past has been close to a black box. Slowly we develop tools, fossils

and archaeological evidence tell us a little about the deep past, carbon dating can tell us about

the age of something. Altogether though, the story they tell is incomplete. Then just about a

decade ago we came up with a new tool. Scientists drilled into 40,000 year old bones and were finally

able to sequence the entire genome of an ancient person. This was an earthquake. All of a sudden,

there was a brand new way of analyzing our past, our extremely ancient past, and it gave us a huge

amount of new information. But it also just blew up a lot of what we thought we understood. Over

the last decade, it's forced scientists to rewrite a wide swath of history. And one of these
