This week we’re giving Rick yet another opportunity to speak enthusiastically about his beloved octopuses, as we try to determine: what is the most intelligent animal. This episode is full of fascinating animal experiments, involving crows, elephants, chimpanzees, horses and more. We also discover what the challenges are when measuring intelligence and how we can compare intelligence between different species. Rick is in his absolute element this week! Special thanks to today’s expert, Dr Marta Halina. Hosted on Acast. See acast.com/privacy for more information.
