SUMMARY

The discussion centers on Woese's model of evolution, which utilizes 16/18 rRNA as a basis for a more accurate representation of evolutionary relationships compared to the classical model. Participants express varying levels of familiarity with Woese's model, with some recognizing the evolutionary tree but not associating it with Woese's name. Key resources include Woese's papers available on PubMed Central, which provide insights into his proposed model and its implications for understanding cell evolution.

PREREQUISITES
  • Understanding of 16S/18S rRNA sequencing
  • Familiarity with phylogenetic trees
  • Basic knowledge of evolutionary biology concepts
  • Access to scientific literature databases like PubMed Central
NEXT STEPS
  • Read Woese's paper on the universal phylogenetic tree available at PubMed Central
  • Explore the implications of 16/18 rRNA in microbial phylogeny
  • Investigate the differences between classical and Woese's models of evolution
  • Study the impact of Woese's model on modern classification systems in microbiology
USEFUL FOR

Biologists, microbiologists, and educators interested in evolutionary theory, particularly those looking to deepen their understanding of Woese's contributions to the field of phylogenetics.

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 referred to as the woese model before...

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

But yeah, that's 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.
