Phylogeny of old
world monkeys
(Purvis, 1995),
with some clades
collapsed to
facilitate
presentation of
data. The terminal
branches are
extant species and
their traits are
indicated. In the
left hand column
is presence
(purple box) or
absence (white
box) of sexual
swellings. In the
right hand column
is multimale
(purple box) or
single-male (white
box) mating
system. The pale
shaded boxes
indicate taxa with
both single-male
and multimale
mating systems.
The ancestral
state is most likely
that of no
swellings. There
have been three
gains of sexual
swellings in this
tree (indicated by
