Figure 15.27
Phylogeny of 103 species of
Hawaiian fruitflies (Drosophila)
of the picture-wing group. The
unrooted tree was inferred by
patterns of chromosomal
inversions. The tree can be
rooted by geochronology of
the islands, and comparison
with closely related fruitflies
in South America. Some details
of the tree are inferred by
biogeography rather than
inversion patterns. Species
shown as ancestors may actually
be descendants of the (now lost)
ancestor. The phylogenies
shown above correspond to
the islands below. Redrawn, by
permission of the publisher,
