American Museum of Natural History, New York, until 29 May 2006. http://www.amnh.org/exhibitions/darwin

The American Museum of Natural History in New York bills its new exhibition, Darwin, as the most in-depth ever mounted on Charles Darwin's life and thought. It's also well timed, coming as it does in the midst of litigation over ‘intelligent design’ in Dover, Pennsylvania, and in the run-up to the bicentennial of Darwin's birth in 2009. All that aside, Darwin is splendid: evolutionary biologist Niles Eldredge's exhibition takes us on a fascinating tour through the life of a great thinker, in what is a superb example of the curator's art.

Visitors are greeted at the entrance by a live, and somehow mesmerizing, giant tortoise from the Galapagos (it can also be viewed remotely via webcam at the exhibition's website). They then encounter Darwin's magnifying glass. This serves as an iconic image — throughout the exhibition, a magnifying glass is positioned to allow the viewer a closer look at a specimen, symbolizing the overall theme of Darwin's lifelong devotion to close observation of nature. His theoretical conclusions, which are well explained in the exhibition, rest on a mountain of evidence that he saw with his own eyes. That evidence is presented here in abundance.

There are many noteworthy items on display, including original correspondence, specimens from Darwin's own collection, original notebooks, and pressed plants from the voyage of the Beagle. The writing box that belonged to his daughter Annie is included here (she died at the age of 10). So too is an amusingly exhaustive questionnaire that Darwin sent to ‘gentleman farmers’, enquiring about their experiences with artificial breeding. The atmosphere is congenial: sounds of ocean life are heard in the section devoted to Darwin's voyage on the Beagle; there is a ‘condensed-time’ video of the ‘Sandwalk’ footpath around Darwin's home and workplace, Down House in Kent, UK; and in the exit room, a voiceover of the final words from Darwin's book On The Origin of Species ushers you through a collection of orchids.

“Believing is easy, and knowing is hard, and it's knowing that matters most,” wrote Neil Patterson in his introduction to cell biologist Christian de Duve's recent book Singularities (Cambridge University Press, 2005). Darwin removed the nebulous idea of belief from the discussion. In explaining what we know about the theory of evolution and its originator, given the limitations of what an exhibition can convey, Darwin could hardly be bettered.

When the Darwin exhibition closes at the American Museum of Natural History in New York on 29 May 2006, it will travel to the Museum of Science in Boston, The Field Museum in Chicago, the Royal Ontario Museum in Toronto and the Natural History Museum in London.
