Approximately 10,000 BC: Total human population of the Americas may number around 10,000-30,000; virtually every human settlement in the world, both temporary and permanent, includes the presence of domesticated dogs|
Source for the universal dog ownership: Man's trash was likely dog's lure by Phil and Nancy Seff, November 10, 1999, Deseret News Science/Technology, http://deseretnews.com/, Man's trash was likely dog's lure ["http://deseretnews.com/dn/view/1,1249,125015089,00.html?"]
-- Learning about 40,000-year-old mammals by MITZI PERDUE, Nando Media/Scripps Howard News Service, November 30, 1999, http://www.nandotimes.com AUTHOR'S NOTE: I believe the reporter of the above article made a typographical error in their statement referring to human population for the entire Earth being only 10,000 to 30,000 around 10,000 BC. Instead, I think she was referring to the estimates of population for just the Americas themselves, rather than the world. The context of her statement deals with the numbers of people threatening the megafauna in the Americas with extinction during this period, and cites estimates for both-- but the animal numbers appear to be for only American populations while the human numbers are given as planet-wide. Thus, the statement as typed seems incongruous. It would make better sense if the human number refers to only populations in the Americas, in order to better relate them to animal numbers on the continents of the time. Plus, in another article by the same writer, a figure of under ten million is given for world population in 8,000 BC-- only 2,000 years later from the 10,000 to 30,000 figures given above. ("A positive perspective on population growth" by Mitzi Perdue, Scripps Howard News Service, Nando Media, http://www.nandotimes.com, September 28, 1999). This too would seem to indicate at least one of these numbers is off.

END NOTE |
Keep in mind that rising sea levels worldwide over the past 5000 years may have resulted in such forced dislocations of large populations from established communities (making them more vulnerable to disease, starvation, predation, and stronger inland/higher altitude tribes) as to significantly reduce the world population as one result.
This environment may also have strongly encouraged humanity to drive and expand deeper inland on many continents too-- perhaps laying the groundwork for the mass extinctions of the megafauna in the Americas as one consequence.
