Interesting paper. It's definitely justified in questioning Western scholastic assumptions about the fall, but it does seem a bit redundant that everything else (birds/plants/etc) would be created again exactly as it was before (since Genesis seems to describe them a lot like how they are now), except for humans, and just redo most of it through different means.
Also, if Adam and Eve were physically different due to not requiring any food consumption prior to the fall (for example), how/why were they able to still consume apples? I mean, you could say the details of the world prior to the fall are a divine mystery, but then the theory doesn't really add much anymore, and it's not like Genesis was particularly shy about details to begin with. It does technically prevent science from labeling the creation story as completely allegorical I guess, but reducing it to such a goal would basically just make it another product of western scholasticism:

That being said, pic related is still the most compelling creation+evolution theory I've encountered so far.
