Observation - https://www.inaturalist.org/observations/209642403 I am just curious and no expertise in phylogenetics. context Purpura panama vs persica vs rudolphi: rudolphi is synonymised with one species in some and another in some resources historically. Indian westcoast rudolphi variant is rec…

I have limited experience with building trees, but I noticed that you didn’t include an outgroup (a species outside the group of interest). This is necessary for properly rooting the tree. Also, using single genes is not always reliable for gastropod phylogenies. In particular, mtDNA like COI has b…

You may be able to assume that, but that also depends on things like query cover. In Cepaea there are differences of >10% within species, which is unusually high. I don’t know if this could also happen in marine species. Either way, using a genomic approach like RADseq or UCEs is better. But it’s b…
