I've started reading '
På spaning efter språkets ursprung' (roughly "Hunting for the origins of language") by Sverker Johansson. As far as I know it's only available in Swedish. Johansson attempts to piece together a picture of how and when language developed, using recent research on several fields such as biology, archeology, neurology and liguistics. It looks to be an easy read despite all the science - well written and sprinkled with dry homour.
And yeah, Camus may be up next - well worth a re-visit
