David,

Lately I read Jared Diamonds " Guns, Germs and Steel " and have puzzled over
, just how people crossed over the Wallace line into New Guinea/Aus. over
60,000 years ago. I can't picture a purpose driven event , whereas contolled
navigation would not have occurred then. I harbor a theory that by
observation people discovered that tree trunks float and somehow were able
to connect many trees or bamboo together and set up floating rafts in the
riverways and shores of Indonesia, as many villagers do today. Then
possibly a huge weather event such as a typhoon coupled with an El Nino
period broke a few of these rafts loose and propelled them accross the final
50 miles or so of open water . There are no predominating ocean currents
that could have assisted. Just my own theory.
