If you have not heard enough about fossil primates in the past month already, I will be on today’s edition of BBC Radio 4’s “Material World” to talk about Ida and Afradapis. My interview will follow one about Ardipithecus ramidus with Tim White and Yohannes Haile-Selassie, so if you are interested in primate evolution you should definitely tune in. The program airs in the afternoon in the UK, but in case you miss it it should be available through the show’s website.
