A single chance mutation about a billion years ago caused an ancient protein to evolve a new function essential for multicellularity in animals, according to new research co-led by a University of Chicago scientist. By conducting experiments on 'resurrected' ancestral proteins, the researchers shed light on the origin of a molecular process that allows animals to form and maintain organized tissues. The study, published in the journal eLife on Jan. 7, 2016, i…
