Next year will be the 200th anniversary of the birth of Charles Darwin and the Darwin 200 project is celebrating. The project is a collaboration between the Natural History Museum and various other museums, institutions and organisations with an interest.

There's a list of events on the website - it goes on until the centenary next June - but there are also a couple of interesting online projects in the pipeline as part of the celebrations.

Sonarboria is an evolutionary project involving trees - pick a seed, see how it grows, and see what kind of music it generates (the concept is a little odd, but there's a good Flash demonstration on the site).

And the Evolution Megalab is calling for volunteers to help it track snails across the country. The idea is that the shell of the domestic banded snail can be used to track evolutionary traits. To get involved, register at the site and start filling in reports whenever you see the right snails.
