Which approach is best suited to end Origins debate?

So how do you hope to explain the nested hierarchy, or the patterns of genetic diversity? Only common descent predicts a nested hierarchy. For example, if common design is the rule then bats should have feathers and wings like birds.

@Meerkat_SK5, if you do try to explain the nested hierarchy with your model, please keep in mind everything that we discussed in this thread: Common Ancestry and Nested Hierarchy
