Only the fittest will survive if you visit the Natural History Museum at the weekend for the Darwin exhibition. It was very busy.

How busy?

The exhibition itself is rather good. Just enough detail for all ages on Darwin, his travels, research and theory.

There is also more about him as a family man. Well worth a visit despite the crowds.

Watch out for the two live items – Charlie the iguana and the horned frog soaking itself in a pool of water.
