Theme issue ‘Cultural and linguistic diversity: evolutionary approaches’ compiled and edited by James Steele, Peter Jordan and Ethan Cochrane

The caption for this issue's cover image was incorrect. It should have been ‘Cover image: A split graph showing the results of NeighborNet analyses of the Indo-European lexical data. (See article by Russell D. Gray, David Bryant and Simon J. Greenhill, pp. 3923–3933.)’. This has now been corrected online.
