Wesley: You say:
Evolution as biologists define it has been observed. That is, there exist
instances of phenomena which meet the objective and quantifiable criteria
presented. These range from reversible changes in allele frequency as seen
in peppered moths up through observed speciation events (some of which are
considered to have crossed higher taxa).

I would like to hear the instances you describe that have been observed,
which cross higher taxa. Not that i doubt this has occurred, but I would
like to know who has seen it.
