I’m in danger of becoming a Bill Bryson Bore as come close to finishing his excellent A Short History of Nearly Everything, but I’ve just got the bit about evolution and how species develop and improve over the millennia.
Sometimes evolution can happen a lot quicker, or rather animals learn new tricks to overcome certain situations. Take the story last week that some sheep in the Pennines have learned how to roll, commando-style, across the cattle grids designed to keep them from munching their neighbour’s flower beds.
The theory is that one of them must have got stuck accidentally and escaped by rolling over and over and that the others learned the trick through observation. That’s quite impressive — but if this new skill spreads, none of our gardens will be safe.
