That was not the question before the house! The question was, 'Could
evolution be falsified?' What I suggested above certainly would do that.
The question I was answering was NOT 'Can we explain absolutely everything
about evolution?' That is and always will be a decided 'no'. The two
questions are different. Evolution CAN be falsified, but the observational
data doesn't falsify it.

One can do this with almost any theory and end up saying that we know
nothing about everything. How does Gravity cause bodies to attract?
Gravitons? Then how do gravitons move? What keeps them going at the speed
of light? What IS a graviton? Are there other particles that make up
gravitons, in other words is a graviton a composite particle? etc. etc. etc.

This technique is a bit like the child that always asks why. One can
always say we don't know everthing, but that doesn't mean we know nothing.
