Scientists at Newcastle Centre for Life have created a beer to mark the 200th anniversary of Charles Darwin's birth.
Named Natural Selection in honour of his work about the theory of evolution, it has been produced by the aptly named Darwin Brewery in Sunderland.
An initial brew of 3,000 bottles will be made available on Thursday to mark the anniversary.
The beer has been funded by the Newcastle ScienceFest 09, a 10-day celebration of science.
