A couple of weeks ago there was an episode of the BBC's Infinite Monkey Cage starring (as well as Robin Ince, Prof. Brian Cox and Ross Noble) none other than Keith Jensen and Katie Slocombe! Despite it being a comedy programme, the discussion around language is very sensible and informative and covers Slocombe's work with chimpanzees as well as talk of Vervet monkeys, and Robin comes up with a not unreasonable experiment involving throwing leopards through the air to address some of the questions covered in the study in Diana Monkeys I cover here.
You can listen by going here:
And clicking on: "Are Humans Uniquely Unique?"
Slocombe has been doing great work in the field of science communication for years now. You can check some of her activities here: https://pure.york.ac.uk/portal/en/researchers/katie-slocombe(8c0787a3-9726-444f-8a64-4eacf5cb458a)/activities.html
Also, I'd recommend other episodes of TIMC.
