Montanabw, you really shouldn't be commenting on horse taxonomy or evolution if you admit that you don't have the time or concern to study it. Your implication that Hagerman's Horse is just Equus ferus caballus (Equus caballus) in disquise, for that is almost certainly what you are implying, is not only just plain wrong, it is manipulatively misleading. And I find your comments about 'subgroups' a bit disturbing. It seems as though you believe that subspecies are invalid taxonomic classifications. This is just laughable. If you want to talk about domestic horse breeds go do that on the Horse page. And I can't beleive I have to say this, but you should be made aware that domestic Horse breeds are not of an equal taxonomic status to ancient Horse species.
