Population Structure and Modern Human Origins
This paper reviews statistical methods for inferring population history from mitochondrial mismatch distributions and extends them to the case of geographically structured populations. Inference is based on a geographically structured version of the coalescent algorithm that allows for temporal variation in population size, in the number of subdivisions, and in the rate of migration between sub...
متن کاملMiddle childhood and modern human origins.
The evolution of modern human life history has involved substantial changes in the overall length of the subadult period, the introduction of a novel early childhood stage, and many changes in the initiation, termination, and character of the other stages. The fossil record is explored for evidence of this evolutionary process, with a special emphasis on middle childhood, which many argue is eq...
متن کاملModern human origins: progress and prospects.
The question of the mode of origin of modern humans (Homo sapiens) has dominated palaeoanthropological debate over the last decade. This review discusses the main models proposed to explain modern human origins, and examines relevant fossil evidence from Eurasia, Africa and Australasia. Archaeological and genetic data are also discussed, as well as problems with the concept of 'modernity' itsel...
متن کاملHaplotype trees and modern human origins.
A haplotype is a multisite haploid genotype at two or more polymorphic sites on the same chromosome in a defined DNA region. An evolutionary tree of the haplotypes can be estimated if the DNA region had little to no recombination. Haplotype trees can be used to reconstruct past human gene-flow patterns and historical events, but any single tree captures only a small portion of evolutionary hist...
متن کاملAnatomy, Behavior, and Modern Human Origins
The fossil record suggests that modern human morphology evolved in Africa between 150,000 and 50,000 years ago, when the sole inhabitants of Eurasia were the Neanderthals and other equally nonmodern people. However, the earliest modern or near-modern Africans were behaviorally (archaeologically) indistinguishable from their nonmodern, Eurasian contemporaries, and it was only around 50,000-40,00...
