In their Review “Farmers and their languages: the first expansions” (25 Apr. 2003, p. [597][1]), J. Diamond and P. Bellwood suggest that food production and the Afroasiatic language family were brought simultaneously from the Near East to Africa by demic diffusion, in other words, by a migration 

Topics from this paper

Timing of a Back-Migration into Africa
TLDR
This work has suggested that indigenous North Africans are genetically quite distinct from sub-Saharan Africans, and this difference is reflected in their lighter skin and European/Middle Eastern physical features. Expand
Working toward a synthesis of archaeological, linguistic, and genetic data for inferring African population history
TLDR
What emerges from this review is the importance of using independent lines of evidence in the interpretation of genetic and genomic data in the reconstruction of past population histories. Expand
14 Sub‐Saharan Africa: human genetics
This chapter uses newly derived autosomal genetic data on African populations to propose a population history based on the distributions of eight different ancestral configurations, classified inExpand
Africa from 48,000 to 9500BCE
This chapter sets world historical study within a larger history of periodization, showing the relation between its methodological difficulties and its immense historiographical significance. ItExpand
Africa's Development in Historical Perspective: Africa in World History before ca. 1440
The African Origins of History Barely more than fifty thousand years ago, the ancestors of every single human being alive today lived in Africa. World history to that point was African history. ThatExpand
Population genetic structure in Indian Austroasiatic speakers: the role of landscape barriers and sex-specific admixture.
TLDR
It is proposed that AA speakers in India today are derived from dispersal from southeast Asia, followed by extensive sex-specific admixture with local Indian populations, strongly supporting the first of the two hypotheses. Expand
The role of comparative/historical linguistics in reconstructing the past: what borrowed and inherited words tell us about the early history of Hausa
Hausa, with perhaps as many as 40 million first-language speakers (within the Afroasiatic/Afrasian phylum only Arabic has more), is by far the largest of the 130 or so languages which constitute theExpand
General/Specific, Local/Global: Comparing the Beginnings of Agriculture in the Horn of Africa (Ethiopia/Eritrea) and Southwest Arabia (Yemen)
The Horn of Africa and Southwest Arabia are less than 30 km apart, yet the timing and nature of transitions to agriculture along the margins of the southern Red Sea differ substantially. This paperExpand
History in the interpretation of the pattern of p49a,f TaqI RFLP Y‐chromosome variation in Egypt: A consideration of multiple lines of evidence
  • S. Keita
  • Geography, Medicine
  • American journal of human biology : the official journal of the Human Biology Council
  • 2005
TLDR
A synthesis of evidence from archaeology, historical linguistics, texts, distribution of haplotypes outside Egypt, and some demographic considerations lends greater support to the establishment of the establishment, before the Middle Kingdom, of the observed distributions of the most prevalent haplotypes V, XI, and IV. Expand
Reminiscences of the cultivated plants early days as treasured by ancient religious traditions: the mustard crop (Brassica spp. and Sinapis spp.) in earliest Christian and Islamic texts
  • A. Mikić
  • Biology
  • Genetic Resources and Crop Evolution
  • 2015
TLDR
This short communication shows that the religious symbolism may cast more light onto the earliest days and history of the cultivated plants, such as mustard, by demonstrating the existence of a peculiar space–time continuum from the beginnings of agriculture to the beginning of common era. Expand

Origin, diffusion, and differentiation of Y-chromosome haplogroups E and J: inferences on the neolithization of Europe and later migratory events in the Mediterranean area.
TLDR
The phylogeography of Y-chromosome haplogroups E and J was investigated in >2400 subjects from 29 populations, mainly from Europe and the Mediterranean area but also from Africa and Asia, revealing spatial patterns that are consistent with a Levantine/Anatolian dispersal route to southeastern Europe.

Brief communication: Y-chromosome haplotypes in Egypt.
TLDR
Y-chromosome haplotypes in the Nile River Valley in Egypt are analyzed in 274 unrelated males, using the p49a,f TaqI polymorphism, finding that Haplotype V is a characteristic Arab haplotype, with a northern geographic distribution in Egypt in the River Valley. Expand
The phylogeography of Y chromosome binary haplotypes and the origins of modern human populations
TLDR
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 from Africa, which can be interpreted as subsequent colonizations, differentiations and migrations overlaid upon previous population ranges.
