Right, well my head goes blank when someone says 'mumble something million years ago' 'cos I've got nothing to hang that on.
But the other day I was listening to an interview of Louise Leekie (grand-daughter of Louis Leekie and also an anthropologist) and she had a neat analogy:
Take a 400 sheet roll of toilet paper and roll it out flat.
If the other end is when the Big Bang was, and this end is 2017, then the dinosaurs got started about 7 sheets back, and ended about 2 sheets back.
And homo sapiens? We're the very last 0.6mm of the roll.
But with the first signs of what we call 'civilisation' emerging just 0.017mm ago.
Well, I liked it...not that I have the faintest clue what to 'do' with it..........(the analogy, that is, I've worked the paper out)........
