It seems to me though that we built upon the findings of Kepler and Galileo- that there were genuine discoveries in the work of early astromeners even is other of their findings didn't hold up. Evolution is not like that as a theory- it is in utter tatters. And Modern Genetics did much to destroy it.
If you're right then evolution will go the way of Freudian psychoanalysis, phlogiston, epicycles, alchemy, astrology, phrenology, and lots of other theories that didn't make it.
But if evolution is thrown out because it can't explain new evidence I very much doubt we'll return to theories that couldn't even explain the old evidence. A good theory will have to explain all the current evidence and stand up, at least for awhile, to new discoveries.
