One of the reasons I feel entitled as the originator of a thread (and in some ways feeling kinda ‘responsible’ for it) and therefore sometimes for closing it (prefer the word closing rather than locking) is when it drifts too far off topic.

This thread is about Neanderthals v Humans – not about Scots/Picts/Celts/Romans/Saxons/etc. Maybe a separate thread under that heading would be appropriate?
