African populations and the evolution of human mitochondrial DNA.
The proposal that all mitochondrial DNA (mtDNA) types in contemporary humans stem from a common ancestor present in an African population some 200,000 years ago has attracted much attention. To studyExpand

Mitochondrial DNA sequences in single hairs from a southern African population.
Hypervariable parts of mitochondrial DNA (mtDNA) were amplified enzymatically and sequenced directly by using genomic DNA from single plucked human hairs. This method has been applied to study mtDNAExpand

Genetic relationship of Chinese ethnic populations revealed by mtDNA sequence diversity.
The origin and demographic history of the ethnic populations of China have not been clearly resolved. In this study, we examined the hypervariable segment I sequences (HVSI) of the mitochondrial DNAExpand

Natural history of Ashkenazi intelligence.
This paper elaborates the hypothesis that the unique demography and sociology of Ashkenazim in medieval Europe selected for intelligence. Ashkenazi literacy, economic specialization, and closure toExpand

Fitness and fertility among Kalahari !Kung.
In this paper we develop a model that examines fertility and childhood mortality patterns and their relationship to environmental variables. Interactions among environmental variables can account forExpand

A Sociobiological Perspective on the Development of Human Reproductive Strategies
A current view in the human sciences emphasizes an understanding of the individual as a representative of a past history of selection for survivorship and reproduction. All of us are descendants ofExpand

Genomics refutes an exclusively African origin of humans.
Ten years ago, evidence from genetics gave strong support to the "recent African origin" view of the evolution of modern humans, which posits that Homo sapiens arose as a new species in Africa andExpand

Group differences in proneness to inflammation.
All humans are primarily descendants from a diaspora out of Africa approximately 50,000 years ago although there are some indications of admixture with local populations of archaic humans outsideExpand

Comparative Genomic and Phylogenetic Approaches to Characterize the Role of Genetic Recombination in Mycobacterial Evolution
The genus Mycobacterium encompasses over one hundred named species of environmental and pathogenic organisms, including the causative agents of devastating human diseases such as tuberculosis andExpand

Kinship and Population Subdivision
The coefficient of kinship between two diploid organisms describes their overall genetic similarity to each other relative to some base population. For example, kinship between parent and offspringExpand
