Paper Summary:
Arrival of the original Australians has long been a topic of debate amongst anthropologists and archaeologists. The questions of why, how and when Greater Australia was colonized are often asked. The biogeographic colonization model proposed by Peter Veth has galvanized archaeologists into pursuing specific questions at regional levels. This paper looks at that model using the following format.

From the Paper:
"Paleoenvironment information is derived from 'geomorphological and paleoecological research in Australia and New Guinea? (Mulvaney and Kamminga 1999). Sites at Lake Fromme, Lake Eyre and Willandra indicate higher precipitation rates from 40,000 to 25,000 BP, followed by a colder drier climate c. 21,000 ? 15,000 BP, known as the Last Glacial Maximum (LGM). During the LGM sea levels were 130 metres below present shorelines increasing Australia's overall land area, connecting New Guinea in the North and Tasmania to the South. Mulvaney (1999:116) suggests a reduction in warm surrounding ocean and increased landmass was responsible for creating intense inland aridity. Paradoxically, the intense aridity associated with the LGM palaeoenvironment coincides with human occupation dates for the arid region. Although, Ross et al., (Lourandos 1992) maintains ?The arid interior has always been dry, in geomorphic terms.? During this period, inland lake levels fluctuated until c. 14,000 BP when most inland lakes became dry, possibly extending the arid area into present day semi?arid boundaries (Fig. 1) until "a general climatic amelioration [began] towards the start of the Holocene" (Lourandos 1997)."
