Sir, - In the final paragraph of his letter, your correspondent Mark McCormick (November 23) makes the remark that "many scientists cling to the theory of evolution despite profound factual difficulties such as those presented by the fossil record". On the contrary, the fossil record shows that the further back one goes in time, the simpler the life forms and there has never been found an exception to that rule. - Yours, etc.,
John Kerney,Dalkey Grove, Dalkey, Co Dublin.
