A manuscript co-authored by Angel Carracedo, from the University of Santiago de Compostela, and (always according to him) pre-accepted in Nature, will offer more insight into the population substructure of Spain, based on autosomal DNA.
Carracedo’s lecture about DNA (in Galician), including his summary of the paper (from december 2017):
Some of the points made in the video:
The study shows a situation parallelling – as expected – the expansion of Spanish Medieval kingdoms during the Reconquista (and subsequent repopulation).
In it, the biggest surprise seems to be the greater substructure found in Galicia, the north-western Spanish
Agriculture first reached the Iberian Peninsula around 5700 BCE. However, little is known about the genetic structure and changes of prehistoric populations in different geographic areas of Iberia. In our study, we focused on the maternal genetic makeup of the Neolithic (~ 5500-3000 BCE), Chalcolithic (~ 3000-2200 BCE) and Early Bronze Age (~ 2200-1500 BCE). We report ancient mitochondrial DNA results of 213 individuals (151 HVS-I sequences) from the northeast, central,
Haplogroup R1b-M269 comprises most Western European Y chromosomes; of its main branches, R1b-DF27 is by far the least known, and it appears to be highly prevalent only in Iberia. We have genotyped 1072 R1b-DF27 chromosomes for six additional SNPs and 17 Y-STRs in population samples from Spain, Portugal and France in order to further characterize this lineage and, in particular, to ascertain the time and place where
This is the story of how an unethical individual, who regards fundamental rights differently as applied to him and to others, can manage to frighten a company to the extent of making them think about limiting his clients’ freedom of expression, with a simple home-made “cease and desist” email threat. No China, no Cuba, no Iran involved. Just Spain in 2009. Too sad to be true.
