"the research shows that genetic miscopyings occur"

oops - sent too soon - I should have said

"the research shows that genetic miscopyings occur which are transmitted to the next generation. This occurs due to changes in the actual germ cells of the creature undergoing the environmental stress - a breakthrough discovery, but the demonstrated mechanism now does exist to explain why genetic pattern changes can occur 'relatively rapidly', i.e. over non-geological time periods, and that relatively simple causal mechanisms also exist."
