Re: The sixth sense

Evolution does not bring about genetic change.  Mutation does, and selection 
acts upon those mutations to cause evolution which is simply change in an 
organism over time. Anyone who doubts that evolution can work either fast or 
slow please explain the resistance to pesticides by insects or the resistance 
of microbes to antibiotics this can occur in relatively few generations 
(short generations). As for the coelacanth, mant succesful organisms do not 
change over time ie. horseshoe crabs.  But "speciation" leads to other other 
species breaking off from a give lineage for a variety of reasons such as 
isolation, climate change, etc.
