Resumen de Simple algae take clumping leap of evolution
A key evolutionary jump has been witnessed in the lab. A single-celled alga has evolved a crude form of multicellularity In the lab--a configuration it never adopts in nature. It has given them a chance to replay one of lifes most important evolutionary leaps in realtime. No single-celled organism people know of has evolved to become multicellular in the past 200 million years, so the process is difficult to study. To force it to happen In the lab, Will Ratcliff and Michael Travisano at the University of Minnesota in St Paul and their colleagues grew 10 cultures of the alga Chlamydomonas reinhordtii.
