I know I am not supposed simply to ‘Plug’ things I’ve seen on tv on* here, but today I’ll make an exception. I think everyone should watch ‘David Attenborough’s first Life’ – it is a magnificent, fascinating programme about how life on earth began. I’m something of an Attenborough fan; he has amassed an immense body of work cataloguing life on this planet. Each one of his series is a gem in itself, but when viewed as a whole, his contribution both to television and the nation’s understanding of science astounds me. This latest programme just adds a final masterstroke to that body of work. I entreat you all to go watch.
