Also suggested is that the population size has never dropped to a few individuals, even in a single generation. These impose important requirements for the hypotheses for the origin of modern humans: a relatively large population size and frequent migration if populations were geographically subdivided. Any hypothesis that assumes a small number of founding individuals throughout the late Pleistocene can be rejected. Extraordinary polymorphism at some loci of the major histocompatibility complex (Mhc) rules out the past action of severe bottlenecks, or the so-called founder principle, which invokes only a small number of founding individuals when a new species emerges. This conclusion may be extended to the 35-Myr-old history of the human lineage, because some polymorphism at Mhc loci seems to have lasted that long. Furthermore, although the population structure prior to the late Pleistocene is less clear, owing to the insensitivity of Mhc alleles, even to low levels of migration, the nature of Mhc polymorphism suggests that the effective size of populations leading to humans was as large as 105. Hence, the effective population size of humans might have become somewhat smaller in most of the late Pleistocene. The reduction could be due either to the then adverse environment in the Old World and/or to the increased migration rate. It is also argued that population explosion fostered by the agriculture revolution has had significant effects on incorporating new alleles into human populations.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Oxford University Press "}]},"item_10001_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"8450756","subitem_relation_type_select":"PMID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1093/oxfordjournals.molbev.a039995 "}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1093/oxfordjournals.molbev.a039995 ","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2013 Society for Molecular Biology and Evolution "}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"07374038 ","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"TAKAHATA, Naoyuki"}],"nameIdentifiers":[{"nameIdentifier":"778","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Allelic genealogy and human evolution","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Allelic genealogy and human evolution"},{"subitem_title":"Allelic genealogy and human evolution","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"21","path":["314"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-07-08"},"publish_date":"2013-07-08","publish_status":"0","recid":"3753","relation_version_is_last":true,"title":["Allelic genealogy and human evolution"],"weko_creator_id":"21","weko_shared_id":21},"updated":"2023-06-20T14:30:43.435856+00:00"}
