Evolution: the evolvability enigma.
A report that a switch of a yeast protein to a 'prion' state triggers diverse phenotypic changes has prompted re-examination of the processes of evolution. To what extent should processes of gene expression and control be interpreted in terms of their capacity to allow future evolution as well as present adaptation?
