On Monday evening there was a minor error in one of the numbers I quoted for the development of life on Earth.
I suggested a time scale for the emergence of multi-cellular life on Earth that was, if I had looked at it for more than 5 seconds (which I clearly didn’t) would have realised was a few orders of magnitude out! This error was rapidly pointed out to me by the attentive and observant audience.
The correct time scales for the start of multi-cellular life was between 1 and 2 billion years ago, 2/3 billion years after the formation of the Earth, depending on what theory you subscribe to. It then wandered out of the ocean and up the beach some 600 Million years ago.
So apologies, but then what’s a few zeros between friends? (E&OE)
No worries Kevin – I was none the wiser!
It was a very interesting talk thanks very much
