Nearly 150 years after Charles Darwin published On the Origin of Species, evolution has been widely accepted by scientists -- and, except for a few religious dogmatic types, the public -- as the blueprint for the engine of life.

But not every scientist thinks that evolution as it's now understood and applied is complete. They want to scale it up to the level of populations, even whole ecosystems. Moreover, they say evolution is intertwined with other dynamics that science is just starting to understand.

"The process of evolution is fundamental to the universe. Biology is the most obvious manifestation of it," said Carl Woese, a legendary microbiologist and one of the first proponents of this newly revised evolutionary framework.
