| 内容記述 | In order to examine the possibility of multiple founding populations of anatomically modern Homo sapiens, we collected DNA sequence data from 10 X-chromosomal regions, 5 autosomal regions, and 1 Y-chromosomal region, in addition to mitochondrial DNA. Except for five regions which are genealogically uninformative and two other regions for which chimpanzee orthologs are not available, the ancestral sequence and population for each of the remaining regions were successfully inferred. Of these 10 ancestral sequences, 9 occurred in Africa and only 1 occurred in Asia during the Pleistocene. Computer simulation was carried out to quantify the multiregional hypothesis based solely on the premise that there was more than one founding population in the Pleistocene. Allowing the breeding size to vary among the founding populations, the hypothesis may account for the observed African ancestry in 90% of the genomic regions. However, it is required that the founding population in Africa was much larger than that outside Africa. Likelihood estimates of the breeding sizes in the founding populations were more than 9,000 in Africa and less than 1,000 in outside of Africa, although these estimates can be much less biased at the 1% significance level. If the number of African ancestral sequences further increases as more data accumulate in other genomic regions, the conclusion of a single founding population of modern H. sapiens is inevitable. | |||||||||||
