The Handshake

Friends do it, strangers do it and so do chimpanzees - and it's not just deeply embedded in our history and culture, it may even be written in our DNA. The humble handshake, it turns out, has a rich and surprising history.

So let's join palaeoanthropologist Ella Al-Shamahi as she embarks on a funny and fascinating voyage of discovery - from the handshake's origins (at least seven million years ago) all the way to its sudden disappearance in March 2020. Drawing on new research, anthropological insights and first-hand experience, she'll reveal how this most friendly of gestures has played a role in everything from meetings with uncontacted tribes to political assassinations - and what it tells us about the enduring power of human contact.

Because the story of the handshake ... is far from over.
