Attenborough on Darwin
When Sir David Attenborough announced last year that Life in Cold Blood would be his last major TV series, somehow you knew it wouldn't be the last we'd see of natural history's dominant silverback.
Well, now 82-year-old Sir David is back and - if anything - feistier than ever.
Watching Charles Darwin and the Tree of Life you get the impression that "retirement" has been good for him. After a career spent studiously compiling and presenting the evidence, Sir David seems to have shaken off the straightjacket of scholarly impartiality. Finally we get to hear what he really thinks.
It's strong stuff. Like the invasion of England by William the Conqueror, evolution is a fact - if anything it's better supported by the evidence, because there's so much more of it.
"Above all Darwin has shown us that we are not apart from the natural world - we do not have dominion over it," Sir David says. "We are subject to its laws and processes as are all the other animals on earth to which indeed we are related."
One by one, and using a fair amount of archive footage featuring a familiar - if somewhat younger - presenter, Sir David demolishes the arguments employed to refute Darwin's theory with his usual headmasterly charm.
It's a powerful piece of film making, and you get the impression that only a figure of such stature in the world of natural history could do it justice. Perhaps they should have called it Attenborough on Darwin and left it at that.
