What would this look like and why not continue?
It would look like the picture I posted above showing exactly that, do you ever read these threads before you post Robert or does seeing anything marsupial related just trigger a natural instinct to post the first thing that comes into your head, which naturally happens to be your usual ide fixe?
As for why not a central pouch wouldn't necessarily persist? Because certain configurations favoured increased reproductive success for specific ecological niches. So if a backward facing pouch tends to improve the survival of young in burrowing animals then that would be a factor leading to differential reproductive success of those animals with such a pouch and tending to increase the prevalence of backward facing pouches if the trait was heritable and potentially of favouring over time more backward facing pouches.
Nothing was seen but a creationist idea easily trumps a evolutionist one.
You haven't really articulated a coherent creationist idea. Saying that a fold of skin 'becomes part of the DNA' is biologically meaningless. Are you thinking of something along the lines of Waddington's '
Genetic Assimilation'?

Nothing was witnessed and so my fold of skin is a good option for what is more likely.
You still are trying to make a movie of each stage of a moving pouch being greatly fine with generations of the creature.
You have it spinning it around and then presto it finds its right place as it is now.
If its spinning then why not speculate its gone around the block several times? how would you know?
You can always say its moving but theres no evidence of this.
The only evidence is what is now found.
All pouches fit just fine, save a few cases of being non existent or seasonal, and it makes a reasonable conclusion they are merely folds in the skin that were pased on to off spring.
This all starting from a need to store the fetus so as to get another one growing in the womb for creatures in a rush to repopulate the earth with the farthest areas showing this most.
marsupialism is simply about reproduction. the change is exactly why there was a change in creatures otherwise spot on identical to others on earth.
