Genome wide variation in the Angolan Namib desert reveals unique Pre-Bantu ancestry

The paper analyzes genome-wide data from populations in the Angolan Namib Desert to reveal unique Pre-Bantu ancestry in peripatetic groups.

Ancient genomes from the last three millennia support multiple human dispersals into Wallacea

The paper analyzes ancient genomes from Wallacea to show multiple human dispersals, with southern islands showing earlier Asian contributions than previously thought.

Mozambican genetic variation provides new insights into the Bantu expansion

The paper analyzes genetic data from Bantu-speaking populations in Mozambique and Angola to trace the Bantu expansion, finding a North-South dispersal pattern and genetic substructure.

The role of matrilineality in shaping patterns of Y chromosome and mtDNA sequence variation in southwestern Angola

The paper analyzes Y chromosome and mtDNA variation in southwestern Angola to explore the impact of matrilineality on genetic diversity and population history.

The maternal genetic history of the Angolan Namib Desert: a key region for understanding the peopling of southern Africa

The paper analyzes maternal genetic structure in Namib Desert populations to evaluate peopling hypotheses, finding strong Bantu influences and endogamous matriclanic systems.

Migration and interaction in a contact zone: mtDNA variation among Bantu-speakers in southern Africa

This study analyzes mtDNA variation among Bantu-speakers in southern Africa to assess genetic differentiation between Eastern and Western Bantu branches and admixture with local populations.
