Teori saingan yang paling kuat adalah [[asal usul multiregional manusia modern]], yang melihat segelombang ''Homo sapiens'' berhijrah dari Afrika, kemudian berbaur dengan [[populasi]] ''[[Homo erectus]]'' setempat di beberapa kawasan bumi. Kebanyakan multiregionalis tetap melihat Afrika sebagai sumber utama keanekaragaman genetik manusia, namun memperkirakan peranan yang jauh lebih besar bagi pencampuran.<ref name="JurmainKilgore2008">{{cite book|author1=Robert Jurmain|author2=Lynn Kilgore|author3=Wenda Trevathan|title=Essentials of Physical Anthropology|url=http://books.google.com/books?id=TSaSPza9LMYC&pg=PA266|accessdate=14 June 2011|date=20 March 2008|publisher=Cengage Learning|isbn=9780495509394|pages=266–}}</ref><ref>{{cite journal|pmid=10766948 | doi=10.1002/(SICI)1096-8644(200005)112:1<129::AID-AJPA11>3.0.CO;2-K}}</ref>
