Are you trying to say that there is some kind of law preventing evolution from creating superficially similar animals?
Dr Hunter's view is not accurate. The environment "causes" the adaptation to a particular niche, by selecting mutations.
Now, as I said, he just has to prove that morphological convergences are impossible, even if they result from different mutations.
I also would like to know his hypothesis. First, do placentals and marsupials share a common ancestor?
