I am unable to understand how GTDB taxonomy lineage is prepared such that we have the same “order” taxa name despite being in different “phylum” taxa names?
Look at following example:
Bacteria;Bacillota;Clostridia;Lachnospirales;Lachnospiraceae;Blautia_A;Blautia_A wexlerae
Bacteria;Bacillota_A;Clostridia;Clostridiales;Clostridiaceae;Clostridium;Clostridium septicum
Shouldn’t the higher resolution taxa names (order, family, genus, species, strain) start to separate away from the lower resolution (kingdom, phylum) since the reference genomes are already differentiated at the lower level (phylum)? Why is the taxonomy lineage regrouping at the level of “order”?
PS there are many more species following said pattern
