Admixture into and within sub-Saharan Africa

Similarity between two individuals in the combination of genetic markers along their chromosomes indicates shared ancestry and can be used to identify historical connections between different population groups due to admixture. We use a genome-wide, haplotype-based, analysis to characterise the structure of genetic diversity and gene-flow in a collection of 48 sub-Saharan African groups. We show that coastal populations experienced an influx of Eurasian haplotypes over the last 7000 years, and that Eastern and Southern Niger-Congo speaking groups share ancestry with Central West Africans as a result of recent population expansions.



A set of arms and armour from Sudan: the influence of Mamluk Egypt on the military equipment of the African hinterland

Dear friends,

First, a briefing on the disablement of the comments:

Concerning the disablement of the comments on the posts, I had to do so due to the lack of time. Because, for me not to answer to your comments is something that I consider as inappropriate. However when it will be possible again (soon, I believe) I’ll activate the comments .

Thank you so much for your consistent preference to ‘Delving into History’.

This set of arms and armour from Sudan denotes the influence of Mamluk Egypt on the military equipment of the African hinterland Muslim states: mail armour, kalkan-type shield, helmet with nose-guard, and straight sword of the 16th or the 17th century from Sudan, which clearly imitate the respective arms and armour of the Mamluks (unknown museum).
In comparison, in the second image I present an Ottoman set of armour, helmet and metal shield identical to those used by the Mamluks of Egypt and Syria (unknown museum).


Rethinking the dispersal of Homo sapiens out of Africa

Republication from Wiley Online library

Current fossil, genetic, and archeological data indicate that Homo sapiens originated in Africa in the late Middle Pleistocene. By the end of the Late Pleistocene, our species was distributed across every continent except Antarctica, setting the foundations for the subsequent demographic and cultural changes of the Holocene. The intervening processes remain intensely debated and a key theme in hominin evolutionary studies. We review archeological, fossil, environmental, and genetic data to evaluate the current state of knowledge on the dispersal of Homo sapiens out of Africa.


Extensive West Eurasian admixture throughout the African continent revealed

Reoublication from Science mag

Characterizing genetic diversity in Africa is a crucial step for most analyses reconstructing the evolutionary history of anatomically modern humans. However, historic migrations from Eurasia into Africa have affected many contemporary populations, confounding inferences. Here, we present a 12.5x coverage ancient genome of an Ethiopian male (‘Mota’) who lived approximately 4,500 years ago. We use this genome to demonstrate that the Eurasian backflow into Africa came from a population closely related to Early Neolithic farmers, who had colonized Europe 4,000 years earlier.

New species of hominin discovered


An international team of scientists announced the discovery Thursday of a new species of hominin, a small creature with a tiny brain that opens the door to a new way of thinking about our ancient ancestors.

The discovery of 15 individuals, consisting of 1,550 bones, represents the largest fossil hominin find on the African continent.
