History
Aboriginal people have
been living in Australia for more than 40,000 years, perhaps 60,000 or
more. Over such a long period of time, Australia went through various
changes in climate and habitat. Temperatures began to rise 14,000
years ago and by 10,000 years ago the vegetation patterns reached approximately
their present condition.
Over such a long period, and with such major changes,
it is impossible to imagine any group of people remaining culturally and
technologically static. Archaeological research has made significant efforts
to discover the kinds of responses which Aboriginal people made to these
changes. Stone tools show little change through the period of first human
arrival to about 10,000 years ago. However, these tools were mainly simple
ones used to create other tools out of wood and therefore it might be
expected they would not change much in form. These wooden tools rarely
survive in the earth, but we know from one unique archaeological find
that boomerangs and barbed spears were invented more than 10,000 years
ago. Rock art also shows changes in wooden tools and such other perishable
items as headdresses.
