Lisongo. In the context of comparable published data for other African populations, analyses of each of these has the potential to play a key role in furthering our understanding of the history of click languages in Africa. independently inherited DNA segments indicate that click-speaking Hadzabe and Ju|’hoansi are separated Their language, with the exception of the repertoire of click consonants and accompaniments, is dissimilar to by genetic distance as great or greater than that between any… Expand

Phonemic clicks and the mapping asymmetry: How language emerged and speech developed
  • M. Huybregts
  • Psychology, Medicine
  • Neuroscience & Biobehavioral Reviews
  • 2017
TLDR
The asymmetry suggests primacy of internal language over speech/sign, and evolution of capacity of language preceding externalized language, as well as genetic evidence suggests that externalization of language occurred late in human prehistory. Expand
Genetic diversity of the Sudanese: insights on origin and implications for health
TLDR
The diverse Sudanese gene pool further has the potential to inform on genetic adaptations driven by culture and the environment resulting in unique and interesting traits, some of which are yet to be investigated. Expand
Contributions of African Crops to American Culture and Beyond: The Slave Trade and Other Journeys of Resilient Peoples and Crops
There is a general unawareness of food crops indigenous to the African continent that have contributed to Western culture. This under-appreciation is particularly relevant in the current context ofExpand
Genetic Consequences of the Transatlantic Slave Trade in the Americas
TLDR
This investigation of the transatlantic slave trade is broad in scope in terms of both datasets and analyses, establishes genetic links between individuals in the Americas and populations across Atlantic Africa, yielding a more comprehensive understanding of the African roots of peoples of the Americas. Expand
Mitochondrial HVRI and whole mitogenome sequence variations portray similar scenarios on the genetic structure and ancestry of northeast Africans
TLDR
The observed regional variation and diversity, depicted in various metrics imply that the female lineages in this part of Africa are likely to have been shaped by a longer history of in-situ evolution. Expand
Tracking human population structure through time from whole genome sequences
TLDR
A novel approach based on the Multiple Sequentially Markovian Coalescent (MSMC) to analyze the separation history between populations, and detects traces of extremely deep ancestry between some African populations, with around 1% of ancestry dating to divergences older than a million years ago.

Origin and evolution of Native American mtDNA variation: a reappraisal.
TLDR
Reappraising mtDNA control region sequences from aboriginal Siberians and Native Americans confirms in agreement with linguistic, archaeological and climatic evidence that the major wave of migration brought one population, ancestral to the Amerinds, from northeastern Siberia to America 20,000-25,000 years ago. Expand
Genes, peoples and languages.
TLDR
A method of absolute genetic dating recently introduced uses mutation rates as molecular clocks; it was applied to human evolution using microsatellites, which have a sufficiently high mutation rate. Expand
The Peoples of Southern Africa and Their Affinities
Southern Africa is of special interest to the human biologist. It was the home of early hominids, and is the present home of the Khoisan. In Southern Africa, the study of the effects of racialExpand
The archeology of modern human origins
TLDR
It is argued that the spread‐and‐replacement hypothesis is also more compatible with a third line of evidence: the archeological record for human behavioral evolution, which is far more strongly supported by burgeoning data on the genetic relationships and diversity of living humans. Expand
A back migration from Asia to sub-Saharan Africa is supported by high-resolution analysis of human Y-chromosome haplotypes.
TLDR
Phylogeographic analyses suggest that a large component of the present Khoisan gene pool is eastern African in origin and that Asia was the source of a back migration to sub-Saharan Africa. Expand
A nomenclature system for the tree of human Y-chromosomal binary haplogroups.
  • A. Redd

  • 2002
TLDR
A simple set of rules was developed to unambiguously label the different clades nested within a single most parsimonious phylogeny, which supersedes and unifies past nomenclatures and allows the inclusion of additional mutations and haplogroups yet to be discovered. Expand
Isolation and the origin of the khoisan: Late pleistocene and early holocene human evolution at the southern end of Africa
The debate between the proponents of the Recent African Origin and the Multiregional Evolution models for the origin of anatomically modern humans has not been of great importance to theExpand
The making of the African mtDNA landscape.
TLDR
The results suggest that the southeast Bantu speakers have a composite origin on the maternal line of descent, with approximately 44% of lineages deriving from West Africa, approximately 21% from either West or Central Africa, Approximately 30% from East Africa, and approximately 5% from southern African Khoisan-speaking groups.

Estimating divergence time with the use of microsatellite genetic distances: impacts of population growth and gene flow.
TLDR
A different estimator of population separation time based on microsatellite statistics, T(D), is introduced that does not assume mutation-drift equilibrium, is independent of population dynamics in the absence of gene flow, and is robust to weak migration flow for growing populations. Expand
