This link http://blogs.telegraph.co.uk/culture/christopherhowse/100002162/stone-ag... shows an interesting piece of stone age ware from Northern Spain that has been investigated by the University of Zaragoza.  Even to my beady Hedgehog eyes, the pattern labelled "relief design" looks remarkably like a fish.

But look at the article and comments.  Please tell me, O Human Hank, why are the columnists and readers of such a conservative newspaper so "snotty" about science?   To save youall the bother of registering, the Hedgehog would be glad to receive your comments and feed them back to the author.
