In 1962, an Alemannic burial site containing human skeletal remains was discovered in Niederstotzingen (Baden-Württemberg, Germany). Researchers at the Eurac Research Centre in Bozen-Bolzano, Italy, and at the Max Planck Institute for the Science of Human History in Jena, Germany, have now examined the DNA of these skeletal remains.

This has enabled them to determine not only the sex and the degree of kinship of those people but also their ancestral origins, which provides new insights into societal structures in the Early Middle Ages. The results of this study demonstrate that genetic research can complement research made by archaeologists and anthropologists through more conventional methods. The research was featured on the front cover of the academic journal Science Advances.

Mitochondrial DNA macrohaplogroup L3 basic lineages migrated back to Africa from Asia around 70,000 years ago

Abstract

Background: After three decades of mtDNA studies on human evolution the only incontrovertible main result is the African origin of all extant modern humans. In addition, a southern coastal route has been relentlessly imposed to explain the Eurasian colonization of these African pioneers. Based on the age of macrohaplogroup L3, from which all maternal Eurasian and the majority of African lineages originated, that out-of-Africa event has been dated around 60-70 kya. On the opposite side, we have proposed a northern route through Central Asia across the Levant for that expansion. Consistent with the fossil record, we have dated it around 125 kya. To help bridge differences between the molecular and fossil record ages, in this article we assess the possibility that mtDNA macrohaplogroup L3 matured in Eurasia and returned to Africa as basic L3 lineages around 70 kya.

Abstract

Background

The Tarim Basin in western China, known for its amazingly well-preserved mummies, has been for thousands of years an important crossroad between the eastern and western parts of Eurasia. Despite its key position in communications and migration, and highly diverse peoples, languages and cultures, its prehistory is poorly understood. To shed light on the origin of the populations of the Tarim Basin, we analysed mitochondrial DNA polymorphisms in human skeletal remains excavated from the Xiaohe cemetery, used by the local community between 4000 and 3500 years before present, and possibly representing some of the earliest settlers.
