Population Structure and Modern Human Origins
نویسنده
چکیده
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 subdivisions. Confidence regions are inferred under several models of population history. If the pattern in mitochondrial DNA reflects population growth rather than selection, then the confidence regions reject the multiregional hypothesis of modern human origins more strongly than has previously been possible. They do not reject the replacement hypothesis.

The phylogeography of Y chromosome binary haplotypes and the origins of modern human populations.
Although molecular genetic evidence continues to accumulate that is consistent with a recent common African ancestry of modern humans, its ability to illuminate regional histories remains incomplete. A set of unique event polymorphisms associated with the non-recombining portion of the Y-chromosome (NRY) addresses this issue by providing evidence concerning successful migrations originating fro...
متن کاملDid a discrete event 200,000-100,000 years ago produce modern humans?
Scenarios for modern human origins are often predicated on the assumption that modern humans arose 200,000-100,000 years ago in Africa. This assumption implies that something 'special' happened at this point in time in Africa, such as the speciation that produced Homo sapiens, a severe bottleneck in human population size, or a combination of the two. The common thread is that after the divergen...
متن کاملGenetic evidence on modern human origins.
A review of genetic evidence leads to the following conclusions concerning human population history: (1) Between 33,000 and 150,000 years ago the human population expanded from an initial size of perhaps 10,000 breeding individuals, reaching a size of at least 300,000. (2) Although the initial population was small, it contained at least 1000 breeding individuals. (3) The human races separated s...
متن کاملMultiregional, not multiple origins.
Multiregional evolution is a model to account for the pattern of human evolution in the Pleistocene. The underlying hypothesis is that a worldwide network of genic exchanges, between evolving human populations that continually divide and reticulate, provides a frame of population interconnections that allows both species-wide evolutionary change and local distinctions and differentiation. "Mult...
متن کاملModern Human Origins and the Evolution of Behavior in the Later Pleistocene Record of South Asia
The archaeological record of Later Pleistocene South Asia has a crucial role to play in our understanding of the evolution of modern human behavior and the dispersal of anatomically modern humans around the Old World. Later Pleistocene records of South Asia are here summarized and placed in the context of the modern-human-origins debate. Aspects of the South Asian record share familiar traits w...
