  Just a quick comment about speciation in fruit flies.  In a book called
*Darwinism Defended*, an historian of science makes a quick reference to
an experiment in adaptation for a colony of fruit flies.  A biologist
tried raising fruit flies using alcohol as their primary food.  Not only did
the fruit flies adapt to the new food over several generations, but they
also began to develop structures that would have made mating with their
parent or originating fly population impossible (due to physical constraints,
not genetic).  The experiment was not continued to see how long a complete
speciation would require for this fruit fly colony.
