With regard to my hypothesis, I do not have the credentials to take it any further myself - but I believe it can be done. The scope obviously must include inception, so it cannot be taken as a frontal assault of the theory of evolution whose technical definition excludes inception.
I do expect to see testable hypotheses forthcoming for I.D., creationism and directed panspermia.
I expect the hypotheses related to directed panspermia to be a natural byproduct of NASA astrobiology and exobiology endeavors. Much research is already in progress there and I expect the directed panspermia proponents to leap-frog from those foundations.
