Why Do We Do That? An anthropologist's guide to the modern world.

There are lots of everyday things which, when you think about them, are pretty weird. Like kissing, doomscrolling and sitting down to go to the loo. Social media may tell you to blame the latest influencer who went viral. Your therapist might tell you to blame your parents. But palaeoanthropologist Ella Al-Shamahi is here to tell you to blame your great, great, great, great, great, etc. grandparents. For some stuff at least. In this series, Ella is joined by some wonderful guests to dive into the cultural, historical and evolutionary story of everyday human habits and behaviour.

Ella Al-Shamahi explores how our Neanderthal DNA may influence our sleeping habits.

Night owl or early bird? Ella Al-Shamahi investigates why we are all different when it comes to sleep. Can we blame our sleeping habits on Neanderthal genes?

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.
