Just a couple additions to your comments: since the gap between
Indonesian land and the Australian continent was approx. 160 km of
water, it is possible that archaic homo sapiens could have constructed
primitive watercraft. This can be accidental, such as floating on water
with logs, or even on purpose. While presently there is not proof of
watercraft, for man to get to Australia it does require some sort of
travel over water.
Similarly, man could have traveled to the Americas across the Bering
strait in non-glaciated times. As you know, the distance here is also
only about 100 km. This way man could travel downwards through Canada
without worrying about glaciers during any sort of ice age. Of course,
this would push the date of human arrival to the Americas back;
remember that we just now have discovered these ancient Australian
dates, and possibly we will find comparable ones in the Americas.
(e.g., At the site at Pedra Furada in Brazil one date was actually found
at 32,000 yrs. B.P.; though most dates in this area are only 8000 yrs.
B.P.) While this is not the conventional theory, it is beginning to
gain support due to the new evidence.
