The Award for Most Innovative Goes to ... Evolution

Aug 22, 2007

In a recent study published in PNAS, scientists at the University of Zurich used statistical models to examine how evolutionary innovation in gene expression patterns is maintained. By studying graphs of genotypes for regulatory networks and resulting phenotypes, they found that there are many random genotypes that exist side by side and lead to the same phenotype, proof that in the long term, genetic mutations in regulatory networks lead to robust phenotypes.
