[QUOTE]Originally posted by Troll Patrol: [QB] [QUOTE]Originally posted by the lioness: [qb] [QUOTE]Originally posted by the lioness: [qb] ^^^^ Troll Patty, jackass, you still can't read and digest the information you post quote: "IF TOBA CAUSED THE BOTTLENECKS THEN MODERN HUMAN RACES MAY HAVE DIFFERENTIATED ABRUPTLY ONLY 70,000 YEARS AGO" [/qb][/QUOTE]Troll Patty no nedd for you to lie the above statement is the last sentece on the PDF you linked here: [IMG]http://picturestack.com/203/996/99ZPicture3bIl.png[/IMG] If pale skin is 6-12,000 years old it means people had become cold adapted "non Africans" for about 60 ka before turning light skinned. unfortunately you do not have the ability to add 2 + 2 and notice what the two studies together mean [/qb][/QUOTE]This is getting hilarious, the study has 29 pages.lol About 6-12,000 years ago a sudden climatic change occurred, dumb turd. Causing a genetic mutation! lol Anyway, [b]The cause, timing and location of bottleneck releases[/b] If population release was due to the natural increase (logistic population growth) of disease-resistant populations following epidemics, then growth could have been relatively rapid, a function of the intrinsic rate of increase of disease-resistant popula-tions, and the duration of the bottleneck relatively brief. Its date could have been at any time, but would presumably have been relatively soon after the bottleneck. Release could have occurred wherever disease-resistant individuals survived. If release was due to natural increase in founder population size after dispersing across land bridges or narrow straits (Lahr, 1996; Lahr & Foley, 1994) then release dates would vary from 70–50 ka for the early Australasian dispersal, to 45 ka for the second Levantine dispersal. In the epidemic and dispersal scenarios the dura-tion of the bottleneck would have been brief. [i]If bottlenecks were caused by the cold, arid climate of isotope stage 4 then their duration was approximately 10 ka and release could have been as late as 60 ka.[/i] [/QB][/QUOTE]
