The fruit fly experiment is interesting on a few levels. It apparently was taken through 600 generations of induced development. I'm not sure about the controls or the method of inducement but am not concerned with that overly for this point.
600 generations of mutation and the fruit fly was a fruit fly, the interesting part is the strong mutation which led to breeding flies. According to the author the original fruit fly would not or could not breed with the result...that's rather vague.
OTOH I've never had any difficulty with inherited characteristics or adaptation within the same GENUS...I accept that, man has developed within the hominid species.
My real DNA based issue is 'transformation'...when did a land mammal or reptile 'decide' to take flight, become a totally different genus....actually how?
How was DNA totally rewritten, not slightly modified by mutation or restacking of present inherited DNA.
This is The Holy Grail of evolution and without some real answers it remains a well supported theory, nothing more.
Scientists of the evolutionary bent have been seeking that Grail for over 150 years to no avail....fossil or DNA type, anything.
Every link 'discovery' has proved to be scientifically wrong or a hoax.
This is the long pole in my cerebral tent....not adaptation within a species or mutation of the same...but the total rewriting of basic and HOX DNA resulting in a new genus.
