Dear qiime 2 team and communities,
Thank you for maintaining and updating the forum meticulously. As a mammalian evolutionary geneticist with not yet enough experience in 16s metagenomics I have a very basic question:
I see is that in our analysis and many other microbial analysis the circular phylogenetic tree group a single bacterial group in two or several different sections.
e.g, In the attached picture blue bacteria (proteobacteria) are found in different places in the
circular tree. It means on the surface that some blue bacteria (proteobacteria) are actually more closely related to the pink bacteria (acidobacteria) than to other proteobacteria ? Is this pattern due to paraphyletic origin of some species or maybe contentious inconsistency between traditional and sequence based taxonomy in bacteria? I appreciate your opinion. I am sure there is something interesting here that I don’t know.
Thanks in advance!
