Blind cave fish

At www.geneticarchaeology.com/research/blind_cavefish_offer_evidence_for_al… … the eyeless cave fish from Mexico present evidence of a mechanism of evolutionary change that is distinct from natural selection of spontaneously arising mutations, according to a paper in the journal Science (Dec 2013). Gene variants that improve the animal's ability to adapt to a new environment can be passed on to progeny, a distinct difference from the established mechanism of chance mutations. The next post at the same site has a piece on rodent evolution which also seems to fly in the face of Darwinian theory – but see also Trevor Palmer, former SIS chairman, 'Catasstrophism, Neocatastrophism, and Evolution' available via the SIS Book Service at just £3.95.
