You miss my point: The presence of 600 species of drosophila in the
Hawaiian Islands that are endemic is not evidence of *no* change. it is
evidence that there are limits to the amount of change a given species can
undergo. These limits are not slight as is obvious from a perusal of the
varieties present there. But they are not becoming other than Drosophila in
a time span that as you so aptly point out contemprorary human evolutionists
posit man and chimpanzee to have derived from a common ancestor. They are
still within the limits of change proscribed by the Drosophila genome.
