Geological evidence suggests that around 650 million years ago, the Earth was covered in ice. It was believed only single-celled organisms could have survived ‘Snowball Earth’. Until Princeton professor, Adam Maloof, found a fossilized sponge predating this by millions of years.

The find inspired Lola Perrin and Alexis Kirke to compose an evening of film, words and music.

And it inspired us to ask Adam onto the show to talk about it.
