It is taught that during the last Ice Age, the ice glaciers took up a lot of the water in the world and the sea levels were lower, revealing land bridges most of the way to Austraila and thereby leaving the water portion of the trip to a small gap of water to cross.
In the picture below, the dark green areas represent the lowest ocean level of the Ice Age and the maximum extent of land expansion. The modern day shorelines are illustrated in the lighter green with the possible routes of entry in red.
The section in the book looks at this argument and discovers that the "small
gap of water" would actually have been 60
kilometers of deep choppy seas. So a crossing
would require that a very sea- worthy craft to be constructed. This would
also entail having a crew well trained in seafaring, as well as a command
and control structure to coordinate the sailing and crew members.
Now
this crossing is supposed to have taken place between 60,000 and 50,000
years ago. At this time, East Asia was in the heart
of the Stone Age (Hunter/Gatherer Age), when
technology only consisted of crude stone tools and animal bone. This would
be nowhere near the level of technology needed for this major seafaring
adventure.
As in the case of the Peopling of the Americas, the oldest sites in Austraila
are found on the Southern Coast at Lake Mungo and Keilor (older than 30,000
years before present); Mammoth Cave and Devil's
Lair (older than 25,000 years
before present).
In
the northern part of New Guinea, there are sites dating to a similar age
at Kuk and Huon Peninsula (older than 25,000 years before present).
The two areas
of oldest occupation are separated by thousands
of miles with the younger sites found in between
them. If there was a link between them, then why would the younger sites
be between the two older sites. It would seem that there should be a gradual
migration, when there are jumps of thousands of miles, followed by a general
slow dispersion.
So
then question comes up.....who peopled Australia??
Answer....no
one knows.
In the most recent edition of
the Scientific American [exact data coming shortly], it has an article
on how new examinations of the supposed "oldest" ancestor of we humans....an
ancient ape known as "Lucy", may acutally be more evolved han previously
thought based on the size and structure on her legs.
The
ones thought to be her decendants and next level in the development of
Mankind, has less developed legs and habits. It even makes the statement
that there is a division among scientists whether or not Lucy is even in
the lineage of humans. Yet, this is still taught in schools today as being
a fact solid and true.
