1) The same way Einsteinian Physics affected Newtonian.
2) I have no idea. The effect would be so fundamental it would take decades to unravel.
It won’t happen but it would meet the “falsifiable” criterion for a Scientific Theory.
_________
That doesn’t make sense. Einsteinium physics did not disprove Newtonian physics.
If any analogous changes in biology are to happen it will be due to comparative genomics.
Is there any realistic result that could happen that can disprove evolution?
>>Is there any realistic result that could happen that can disprove evolution?<<
No, nothing realistic.
One cannot wave away billions of data points assembled over hundreds of years by thousands of scientists.
I just worry about declaring something ipso facto — it really is an unassailable Scientific Theory, probably the best understood one (as a Theory — the mechanics are still being worked out and will probably be refined forever) in all of science.
