Re: Human pretending to be a frog nearly drowns.....

As a biologist he knew a few hours a day in the
water certainly would not turn a creature semi-aquatic, there had to be
a substantial amount of time in the water.

All fully and semi-aquatic mammal's ancestors were once terrestrial,
which re-entered the water gradually "a few hours a day", with their
surviving descendents at some point later on spending a more
"substantial amount of time in the water".

I don't know what Hardy's aquatic-time estimate was based on. I meant,
IMO Homo typically spent about 4+ hours a day fully in water
habitually, the rest of the time in a shoreside/coastal environment
except during mast-fruiting periods or animal migration periods. I
consider them to have been largely a coastal migrant, with savanna and
forest excursions while expanding to riparian and lacustrine
environments. IOW, I don't consider Homo of that early period to be
adapted to long term savanna dwelling.
I've read some Khoisan and Aust. aborigines sleep in sand pockets, I
think Homo slept in sand pockets on the dry beach covered with palm
leaves, being early sleepers and late risers. Just speculation of
course, can't prove either way. DD
