Ricin is an extremely toxic chemical produced by the seeds (or beans) of the "Castor Oil" plant (Ricinus communis). It achieved notoriety when it was used by the bulgarian secret police to assassinate the BBC journalist Georgi Markov on Waterloo Bridge in 1978<ref>[http://news.bbc.co.uk/1/hi/uk/2636459.stm BBC News: Flashback: Dissident's poisoning]</ref>.

Note from the above how the molecule is formed from two seperate protein chains, each from different genes in the plant genome. Without the B chain, the A chain is useless as it only acts intracellularly and has no other method of being injected into the target cell. Without the A chain, the B chain is useless as invagination of the protein into the target cell with no associated payload serves no function, and so this mutation would have died out were evolution in effect. It is implausible that both genes (plus presumably a third gene encoding for a protein to link the two chains) evolved either separately or simultaneously and therefore the molecule is an excellent example of [[Intelligent Design]].
