Here's the latest news. I just read it on the Richard Dawkins net, and thought I should share it here. - http://www.sciencedaily.com/releases/2008/06/080604140959.htm - It's a simulation of what a "protocell" might have been like. And it works, despite being much simpler than the more evolved cells that exist now. Looks like a great step towards explaining the early evolution of life.
