Dr Richard Watson of Southampton University, the co-organiser of the conference, echoes his concerns. “Although Darwin gave us an essential component for the evolution of complexity, it is not a sufficient theory,” he says. "There are other essential components that are missing."
One of these may be “self-organisation”, which occurs when simpler units - molecules, microbes or creatures - work together using simple rules to create complex patterns and behaviour.
…Evolution on its own doesn’t look like it can make the creative leaps that have occurred in the history of life," says Dr Seth Bullock, another of the conference’s organisers. "It’s a great process for refining, tinkering, and so on. But self-organisation is the process that is needed alongside natural selection before you get the kind of creative power that we see around us.
