Four models of modern human origins were described and discussed by Aiello (Aiello, L. (1993) American Anthropologist 95: 73–96. She distinguished them as the African Replacement Model, the African Hybridization and Replacement Model, the Assimilation Model, and the Multiregional Model. All of these models have been modified and refined following further research and development by their proponents, but this is now leading to some confusion in testing the models. Whereas developments of the… Expand
Modern human origins in Australasia: testing the predictions of competing models.

TLDR
The Assimilation model presently offers the best explanation for the origins of Pleistocene Australians, and the results refute the predictions of multi-species replacement models for early Australians but are consistent with single-species models. Expand
Statistical evaluation of alternative models of human evolution
TLDR
Using DNA data from 50 nuclear loci sequenced in African, Asian and Native American samples, it is shown that a simple African replacement model with exponential growth has a higher probability as compared with alternative multiregional evolution or assimilation scenarios. Expand

TLDR
It is concluded that a recent African origin can be supported for H. sapiens, morphologically, behaviourally and genetically, but that more evidence will be needed, both from Africa and elsewhere, before an absolute African origin for the authors' species and its behavioural characteristics can be established and explained. Expand
On the reliability of recent tests of the Out of Africa hypothesis for modern human origins.
TLDR
It is argued that Hawks et al.'s and Wolpoff et al'.s claim to have disproved the Out of Africa hypothesis cannot be sustained and there are significant problems with the character state datasets employed in the studies. Expand
Successes and failures of human dispersals from North Africa
Abstract Under the Out-of-Africa scenario, various routes have been supposed for the exit of the African Homo sapiens . The Mediterranean coast of North Africa, the Sahara, the Nile Valley, the RedExpand
The Genus Homo : Origin, Speciation and Dispersal
TLDR
This contribution discusses the evolution and origin of ‘early’ Homo, the assumed speciation events and the validity and credibility of traditional, newly described or reinterpreted Homo-species and the hypothesized patterns of dispersal. Expand
Pairwise difference analysis in modern human origins research.
TLDR
It is found that the phylogenies yielded by the pairwise difference analyses were incompatible with the molecular phylogeny for the hominoids, suggesting that pairwise different analysis cannot be relied on to generate reliable estimates of primate phylogeny from morphological data. Expand
Forum: The “Africa and the Rest of the World Evolutionary Hypotheses”: An Exercise in Scientific Epistemology
The consensus of the majority of researchers in evolutionary anthropology and paleontology is that the biological species Homo originated in the general area consisting of the eastern and southernExpand
The MSA sequence of Diepkloof and the history of southern African Late Pleistocene populations.
This paper presents the first multidisciplinary synthesis of the Middle Stone Age sequence of Diepkloof Rock Shelter (South Africa). We explore the main cultural changes that characterized southernExpand

Models, predictions, and the fossil record of modern human origins
It is clear from the recent contents of this journal and others that the debate about modern human origins continues unabated. My own foray into this subject has dealt with some of the geneticExpand
Multiregional, not multiple origins.
TLDR
A valid understanding of multiregional evolution would go a long way toward reducing the modern human origins controversy. Expand
Late Pleistocene human population bottlenecks, volcanic winter, and differentiation of modern humans.
  • S. Ambrose
  • Biology, Medicine
  • Journal of human evolution
  • 1998
TLDR
If Toba caused the bottlenecks, then modern human races may have differentiated abruptly, only 70 thousand years ago, and high genetic diversity in modern Africans may reflect a less severe bottleneck rather than earlier population growth. Expand
Population bottlenecks and Pleistocene human evolution.
TLDR
Genetic data cannot disprove a simple model of exponential population growth following a bottleneck 2 MYA at the origin of the authors' lineage and extending through the Pleistocene, and both genetic and anthropological data are incompatible with the hypothesis of a recent population size bottleneck. Expand
Genetic evidence for larger African population size during recent human evolution.
TLDR
A method that allows estimation of relative long-term regional population sizes and average residual heterozygosity is significantly higher in the sub-Saharan African sample, indicating that African population size was larger than other regions during recent human evolution. Expand
Genetic and fossil evidence for the origin of modern humans.
TLDR
Genetic data on present human population relationships and data from the Pleistocene fossil hominid record are used to compare two contrasting models for the origin of modern humans. Expand
mtDNA variation in the South African Kung and Khwe-and their genetic relationships to other African populations.
TLDR
The mtDNA variation of 74 Khoisan-speaking individuals from Schmidtsdrift, in the Northern Cape Province of South Africa, was examined by high-resolution RFLP analysis and control region (CR) sequencing, revealing the significant substructure of macrohaplogroup L* in African populations and suggesting that the Biaka Pygmies could represent one of the oldest human populations.

TLDR
If the authors are able to trace back the coalescence of genomic regions from an ample worldwide sample, they can infer the phylogeny of humans and the goal then may be the evolutionary reconstitution of specific populations or the origin of their species. Expand
Interpretations of Multiregional Evolution
TLDR
The question of a unique African origin for modern humans, the “Eve” theory, is discussed and global patterns of linkage disequilibrium at the CD4 locus and modern human are discussed. Expand
