Certainly it means that the "species" is different from its ancestors. That's all that is necessary for evolutionary theory. Of course, if the Creationists were to define "species" so as to include non-interbreeding entities, they could claim that evolution did not obtain. That's why Creationists seem careful never to define "kind" or "species" or anything else for that matter.
Oh, like "harmful", "beneficial", "improve", "adaptation", etc.,etc.,?
