Show Notes
Are you at one with midnight, or up before sunrise? In this episode, Ella Al-Shamahi investigates when we naturally feel tired and awake, known as our chronotype. Our chronotype depends on our lifestyle, our environment, where we live, and is also influenced by our genes. In this episode, Ella Al-Shamahi uncovers fascinating research which suggests our chronotype can be traced back over 100,000 years ago, to when our early modern human ancestors interbred with Neanderthals. She speaks to geneticist Tony Capra how DNA from our Neanderthal ancestors may be influencing our present-day sleeping habits and shares her revelations with professional early riser and BBC Radio 1 Early Breakfast presenter Arielle Free.

Ella Al-Shamahi explores evolutionary mysteries in More Play with Brenna Hassett. BBC Studios Audio Producer: Olivia Jani Additional Production: Emily Bird Series Producer: Geraldine Fitzgerald Executive Producer: Alexandra Feachem
Paleoanthropologist Ella Al-Shamahi asks why do humans play? The Neanderthals are a species that was so close to us that we could reproduce with them, they had creativity, technology and they made art - handprints on cave walls and painted shells strung into necklaces. But it turns out the Neanderthals had shorter childhoods than us. Their children grew up quicker than their Homo sapiens counterparts. We don’t know why Neanderthals went extinct. It is probably for a few reasons but is it possible that us having these longer childhoods, having more time to play, might have given us a creative edge. There are probably more important reasons for our survival over them but it is food for thought. And we are still playing, anthropologist Brenna Hasset says play is part of learning how to be an adult so depending on where you grow up influences the type of games children play.
