    I have observed that many people have question about evolution. When I look back at high school we got to learn the classical model (see diagram below) of evolution and this model was also though in the university level zoology and plant biology whereas in microbiology we got to learn the Woese model of evolution based on 16/18 rRNA (the paper for the propose model is free on this site http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pubmed&pubmedid=2112744) rather than the classical model. Woese model of evolution (the attach picture show his proposed model) is more accurate than the classical model. Woese also proposed a model for cell evolution that goes with his evolution tree. Here a link for the paper and it's free http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pubmed&pubmedid=12077305

    What I was wodering is how many people are aware of Woese model of evolution?

    If you know Woese's model where did you learn about it.
    If you never hear of Woese's model would you be interrested in learning more (maybe I'll write a paper).

    Classical Model of Evolution (I simplified the model therefore it's not as accurate as desired)

    I see the woese picture of Evolution everywhere, but I have never heard it refered to as the woese model before...

    I did also know of a study of evolution being done based on 16/18 RNA.

    But yeah, thats about it. I think I just heard about it briefly a few times over during the course of my degree...

    It does not matte if you saw Woese name ore not. What I was wondering was if people saw the tree or not before, because it change you perception of evolution.

    Seen the tree, yes. The name "Woese", no.
