Apparently Darwin’s work was decent but according to Carl Woese and physicist Nigel Goldenfeld, both at the University of Illinois at Urbana-Champaign, evolution had a few tricks up it’s sleeve that Darwin, and most of our current evolutionary biologists have overlooked. Lateral genetics? Check it out:
At the root of this idea is overwhelming recent evidence for horizontal gene transfer – in which organisms acquire genetic material “horizontally” from other organisms around them, rather than vertically from their parents or ancestors. The donor organisms may not even be the same species. This mechanism is already known to play a huge role in the evolution of microbial genomes, but its consequences have hardly been explored. According to Woese and Goldenfeld, they are profound, and horizontal gene transfer alters the evolutionary process itself. Since micro-organisms represented most of life on Earth for most of the time that life has existed – billions of years, in fact – the most ancient and prevalent form of evolution probably wasn’t Darwinian at all, Woese and Goldenfeld say.
