How Mitochondrial DNA Can Write Pre-History: Kinship and Culture in Duero Basin (Spain) during Chalcolithic and Bronze Age

The chronological period from the beginning of Chalcolithic Age to end Bronze on Iberian northern sub-plateau Iberic Peninsula involves interesting social and cultural phenomena, such as appearance Bell Beaker and, later, Cogotas I cultures. This work constructs a genetic characterisation maternal lineages human population that lived between 5000 3000 years ago through an analysis mitochondrial DNA (mtDNA), kind marker is inherited lineages, unaltered generation generation. Population questions are investigated mtDNA analyses. study intends shed light following questions. Were individuals who were buried together in multiple or collective burials biologically related their lineages? there distinct same different geographical areas if material cultures (Bell I) associated with arrival new populations established close biological relationships endogenous populations? Or could this be result transmission knowledge without mixing? Another important question whether female populations. We analysed 91 28 archaeological sites four chrono-cultural periods (Pre-Bell Beaker, Proto-Cogotas I, I), up Age. There two historical moments arriving: first during Pre-Bell period, K haplogroup, second culture, H, HVO, T haplogroups. Neither these flows directly maximum development main so they must have occurred immediately beforehand, periods, respectively. However, we cannot discard association Curiously, it has also been observed was tendency towards burials, which belonged lineage, change. some populational changes specific area Peninsula.
