First skull of mysterious human ancestor; Decoding whale language; Heatwaves 20x more likely to happen

Episode 308 An ancient skull discovered in China has been confirmed to belong to a Denisovan. It’s been tough to study this mysterious human ancestor, as we’ve only ever found a finger and jaw bone - so this new discovery could reshape our understanding of them. After being kept secret for decades, the “dragon man” skull is opening up a new window into our past. We’ve unlocked another clue in our quest to decode whale language. Analysis of 15 sperm whales in the Caribbean suggest their language may contain vowels, used in a similar way to human language. Using their various clicks, researchers have discovered interesting patterns in the way they communicate. Feeling hot and sweaty? Well, strap in - because these heatwaves are set to continue…and get worse. Summers are evolving fast as a result of climate change and weather events that would’ve once been rare are becoming much more common. Find out how the UK could be in for a string of long 40C summers in the very near future.
