[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by Swenet: [qb] I like how lioness is learning and (seemingly) coming around. BTW, it might be useful to first tease out where these peoples' ancestors lived before we use them as examples that confirm or fly in the face of commonly accepted selective pressures. For example, looking at present day arid conditions in Australia might cause one to suspect that Australian are an exception to the dry ambient air explanation that is commonly accepted as a selective presure that selects for narrow(er) noses. However, Truthcentric and Djehuti recently posted information that suggests that Australian aboriginals lived mostly in wet and tropical areas, which would mean that their phenotype is [b]not[/b] in violation of commonly accepted principles. [/qb][/QUOTE]Keyword [i]seemingly[/i]. I doubt lyinass will ever come around so long as her anti-black bias prevails. But getting back to Australia, I assume you are referring to the following data: [URL=http://www.austhrutime.com/climate_swings_pleistocene.htm]Climate Swings of the Pleistocene in Australia[/URL] [i] Over the last 2.6 million years the fluctuations of the climate have had a profound effect on the Australian continent, in particular on the surface water and the groundwater. The rivers of Australia, as well as the lakes and dunefields, have been greatly affected by the alternating nature of the climate over the last 300,000 years, swinging from dry periods to wet and back again. [b]There were periods in the last 2 interglacials when fluvial conditions dominated that allowed large sand loads in rivers in the Simpson Desert, as well as southeast Australia.[/b] White describes the central Australian palaeochannels as 'highly competent sand-load rivers during the last interglacial'. 110,000 years ago was the peak of their fluvial activity, behind world temperature and sea level maxima by about 5,000-10,000 years. Following this wet period, aridity spread towards the margins of the continent, the spread of aridity peaking at the last glacial maximum. [b]Between about 55,000 and 35,000 BP a wet phase, that was less widespread, has been associated with high sea levels and activity of palaeochannels in southeastern Australia. The sedimentary record in rivers and lakes, and the time of dune formation, documents the spread of aridity from central Australia towards the coast across the continent...[/b] Over the last 10,000 years, the Holocene, there have been variations of temperature and sea level. [b]At about 9,000 BP the temperatures were higher than at the present in Australia, and there was increased rainfall.[/b] The highest the sea levels reached in the Holocene was from about 7,500-6,000 BP. Since then the sea levels have been approximately stable, though the fact that some low-lying islands are shrinking, with the sea encroaching on villages that have existed on the coast for many years suggests things might be changing.[/i] 'Ecosystem Collapse in Pleistocene Australia and a Human Role in Megafaunal Extinction' Gifford H.
