AFAIK, there is only evidence of speciation, e.g. dog breeds, "Darwin's finches", etc.

There is no evidence for variation outside the the Biblical "kinds", which might very well be the taxonomic classification of family.

It's easy to say "there is no evidence", but reason dictates that proving a negative is going to be problematic. Good luck with that.
