- Jeffrey E. Barrick 13:09, 25 March 2012 (EDT):Please add references to your figure captions.
- Jeffrey E. Barrick 13:09, 25 March 2012 (EDT):For the chromobacteria section, many of these pigments seem to have evolved because they are antibacterial agents (like pyocyanin). It doesn't really matter if these are colored or not for their function. Aside from uv protection and harvesting light energy, I guess color is a random side-effect of the molecular structure in many cases. Is there also a connection that colored compounds (such as heme) are often redox-active?
- Jeffrey E. Barrick 13:09, 25 March 2012 (EDT):We've also talked about how sometimes symbiotic bacteria lend their properties to multicellular animals, like the example of luciferase and squid. I wonder if any colors in higher animals are derived from bacterial symbionts in specialized organelles or horizontal transfer of bacterial genes, rather than from eukaryotic .
- Jeffrey E. Barrick 13:09, 25 March 2012 (EDT):Wow, those radiotrophic fungi are crazy.
