"This year's Nobel Laureates in Chemistry have been inspired by the power of evolution and used the same principles - genetic change and selection - to develop proteins that solve mankind's chemical problems", the Royal Swedish Academy of Sciences said in a statement on awarding the 9 million Swedish crown ($1 million) prize, Reuters reported.

"It's a standard joke that someone with a Swedish accent calls and says 'You won!' But there was so much static on the line, I knew it wasn't any of my friends", he said.

Three scientists - two from the USA and one from Britain - share the 2018 Nobel Prize for Chemistry on Wednesday for harnessing the power of evolution to produce novel proteins used in everything from environmentally friendly detergents and biofuels to cancer drugs.

The other half will be jointly split between George Smith from the University of Missouri, US and Gregory Winter from the MRC Laboratory of Molecular Biology in the United Kingdom who developed a technique called phage display.

The other half will jointly go to George P. Smith, of the University of Missouri, and Gregory P. Winter, from Cambridge University, for their work in evolving new proteins.

The first pharmaceutical created using this method was adalimumab, approved for use in 2002, which is used to treat rheumatoid arthritis, psoriasis and inflammatory bowel diseases. Smith realised that this could be handy: for example if it wasn't known what protein a particular gene gave rise to, it could be put into a phage and the mystery protein would appear on the surface and could be identified.
