Lost on the Information Superhighway

One thing students on my "Technology, Consciousness and Society" course love to say is that with the Internet, anyone can find any information they want. Aside from the fact that half the world's population don't even have access to a telephone, let alone the Internet, it's sometimes hard to find even the simplest things.

Last night I was chatting to my wife about domestic animals (as one does) and the question of the origins of sheep came up. "Oh, I'll look it up on the Internet next time I'm in the office," I said confidently. After over an hour's searching, in which I ploughed through dozens of guides to wildlife and polemics for and against the theory of evolution, I was still unable to find from which animal the modern sheep evolved.

So please, anyone - what was it?
