We're still waiting for the experimental verification part. Hint: an archeological dig is not an experiment. Assembling a complete skeleton from bone fragments is not an experiment.

Setting up a bacterial colony to produce speciation through random mutation under selection pressure would be an experiment.

A simple mathematical extrapolation of the number of current species on the planet since the last mass extinction will give you a good baseline for generations required for speciation when selection pressures are present.

Since bacteria can breed a thousand or more generations in a year, and we can grow many thousands of colonies relatively easy (giving us the statistical equivalent of a billion generations a year), it is relatively straightforward to design an experiment to see if speciation rates in the laboratory are as predicted by evolution and the current interpretation of the fossil record.

THAT would be applying the scientific method to evolution.

I'm not aware of any such experiment ever having been performed.

In fact, I am unaware of ANY experiment performed to measure speciation rates due to random mutation and selection pressures.

Problem is, the criteria we generally use for speciation don't apply to bacteria, which don't need to interbreed to reproduce.

Where is the [allegedly mandatory] experimental verification for any of the following?

1. The solar system
2. Contenintal drift
3. The Big Bang
4. The cause of the "Meteor Crator" at Winslow Arizona
5. The cause of volcanos
6. The existence of periodic ice ages on earth
Would you care to reconsider the necessity of experimental verification?

Received any cites yet? Surely with all of the scientists here one of them should be able to cite ONE experiment.
