P.8 left column bottom paragraph: "Ne is the number of individuals in an ideally behaving, random-mating population that has the same magnitude of genetic drift as the actual population of interest (Wright 1938 Crow and Kimura 1970 Hartl and Clark 1997)." P.9 left column: "Many researchers used mtDNA diversity to estimate the time to the most recent common ancestor, or coalescence time, of human mtDNA. A wide range of estimates was obtained (fig. 5) 200,000 years is a widely accepted median estimate. This estimate allows an estimate of inbreeding Ne [effective population size] of about 8,800 individuals (table 1 )." P.10 right column 4th paragraph: "When considered together (table 1), these gene systems provide substantial evidence with regard to the limits of ancient population size changes. All of the autosomal systems examined to date are consistent with a long-term average Ne on the order of 10^4 to 10^5 for the human species (table 1). Moreover, they are all consistent with earlier analyses of protein polymorphisms (Nei and Graur 1984) and of nucleotide polymorphisms (Li and Sadler 1991 Takahata, Satta, and Klein 1995) that estimated the long-term effective human population size as on the order of 10^4." Table gives the effective population size (Ne) for various nuclear systems. Value of 17500 is close to value of 21000 authors receive through simulation model of population size in past 2MY.
