SUMMARY
Understanding the mechanisms underlying the mor-
phological divergence of species is one of the central
goals of evolutionary biology. Here, we analyze the
genetic and molecular bases of the divergence of
body pigmentation patterns between Drosophila
yakuba and its sister species Drosophila santomea.
We found that loss of pigmentation in D. santomea
involved the selective loss of expression of the tan
and yellow pigmentation genes. We demonstrate
that tan gene expression was eliminated through
