"The Proboscis Monkey lifestyle is both arboreal and amphibious, with its
mangrove swamp and riverine environment containing forest, dry land,
shallow water allowing wading, and deep water requiring swimming. Like
other similar monkeys, the Proboscis Monkey climbs well. It is also a
proficient swimmer, often swimming from island to island, and has been
picked up by fishing boats in open ocean a mile from shore. While wading,
the monkey uses an upright posture, with the females carrying infants on
their hip. Troops have been filmed continuing to walk upright, in single
file, along forest trails when they emerge on land, the only non-human
mammal, with the exception of gibbons and giant pangolins, known to use
this form of locomotion for any length of time."

Good stuff Marc... have you written what you beleive to be the progressive,
or step by step, changes from a creature like the probiscus monkey (our LCA
with Pan) to hss?
and by the way for Day Brown, there is a good article on Wiki about
sexual selection

Chris Stringer: "I have agreed that we lack plausible models for the
origins of bipedalism and have agreed that wading in water can facilitate
bipedal locomotion (as observed in other normally quadrupedal primates). I
have never said that this must have been the forcing mechanism in
hominids, but I do consider it plausible."
