I've always been obsessed with languages (Romance ones preferably, but will also consider others), so it's only natural to take any opportunity to write about science-language interface. There haven't been all that many (the 2012 feature on the evolution of writing and my ancient paper on the linguistics of protein folding spring to mind), but recent work on ancient DNA has yielded a good excuse to revisit the family tree of Indo-European languages, comparing results from archaeology, genetics, linguistics and cultural history.
The resulting feature is out now:
The Indo-European ancestors' tale
Current Biology Volume 28, Issue 12, 18 June 2018, Pages R679–R682
Restricted access to full text and PDF download
(will become open access one year after publication)
Statistical analyses can show that ancient fairy tales have likely evolved from common ancestors of the Indo-European language groups or even from the culture that spoke the Proto-Indo-European language. (Image: From The Folktales of Bengal illustrated by Warwick Goble.)
