Multicellular life arises in a test tube
Common lab yeast normally live as single cells that bud off single-celled offspring. But challenging generations of yeast with conditions that make solo life tough led to spiky multicelled yeast forms within about two months, said Will Ratcliff of the University of Minnesota, Twin Cities. The experiment suggests going multicellular may happen more readily than previously thought, he told the Evolution 2011 conference June 18.
This is far from the first experimental evidence for evolution.
