Or, what is a subspecies anyway?
I heard from this thread that it’s not normal practice (in the scientific community?) to have monotypic subspecies. Why is that?
I’d thought that subspecies were defined as a genetically distinct population that was still close enough to other populations (e.g. defined by free ability to interbreed when ranges overlap) that they could be considered the same species. By that definition there’s no reason why there couldn’t be one such population, with all other populations not being distinct from it or one another. So, clearly my definition’s wrong.
I know nothing and welcome corrections.
