In another answer you agreed on something else ;)
Is the above Peckoltia sabaji enough different to be 2 species? They are 2 different and separated large populations... or is't to early to separate them as 2 specis and we have to wait until the evulotion increase the differencies "enough"?Mike wrote:I am actually of the opinion that nearly all described subspecies should be considered separate species. Can you diagnose the group? Fine, call them a species. You can't? Well, they're a population.
With fish subspecies tend to be distinct & diagnosable - in other words, species.Rupert wrote:My first choice would be to recognise all independently evolving, monophyletic groups as separate species, no matter how small the difference is, and providing data are presented and defended in concordance with our current knowledge of the systems involved.
