I mean, it is an extraordinary thing that a large proportion of your country and my country, of the citizens, never see a wild creature from dawn 'til dusk, unless it's a pigeon, which isn't really wild, which might come and settle near them.

I often get letters, quite frequently, from people who say how they like the programmes a lot, but I never give credit to the almighty power that created nature.

The correct scientific response to something that is not understood must always be to look harder for the explanation, not give up and assume a supernatural cause.

Nothing in the natural world makes sense - except when seen in the light of evolution

How could I look my grandchildren in the eye and say I knew what was happening to the world and did nothing.

I remember when we were in the World Cup in Australia and I had to win the singles against Tony Payne, best of seven legs, to win it. I was 2-0 down but ended up beating him I suffer much less than many of my colleagues. I am perfectly able to go to Australia and film within three hours of arrival.

As far as I'm concerned, if there is a supreme being then He chose organic evolution as a way of bringing into existence the natural world... which doesn't seem to me to be necessarily blasphemous at all.
