He tested his idea in a tiny nematode worm called Caenorhabditis elegans and, in 1994, published a paper showing how touch-receptor proteins are distributed around this worm.
In 1972 Sydney Brenner, a biologist then at Cambridge University, decided to work out the connections of every cell in the nervous system of a small nematode worm called C. elegans.

They discovered that the most closely related parasite to the Onchocerca volvulus worm - the O. ochengi nematode - died after the bacteria living in it were killed by an ordinary antibiotic treatment of tetracycline.
Though RNA editing has been observed before, in animals ranging from humans to nematode worms, this is the first time an edit has been tied to a clear evolutionary difference caused by a feature of the environment in this case ambient temperature.
