I think the neanderthalensis fits more than the Homo erectus in this pic. Also, putting the Equestrian pony and the common horse in the same specie wouldn't make a lot of sense. All the known tigers belong to the same species (but not subspecies) and there are not many differences between them except habitat and size.
