[Taxacom] Invisible evolution, paraphyly

[Richard Zander]

Maybe there's a problem with species definitions, Curtis. Could you tell
us, in short, what the difference is between paraphyletic species and
paraphyletic higher taxa.

If a species is defined as restricted to one population, then
recombination does matter at least for nuclear genes, and assuming the
groups are not asexual, in which case there is a difference. With
haplotypes, or asexually reproducing species, and species with more than
one population (these somewhat or entirely genetically isolated), what
is the difference in paraphyly between species and higher taxa?
