The foremost pioneer of the study of population genetics was Luigi Luca Cavalli-Sforza.Cavalli-Sforza used classical genetic markers to analyse DNA by proxy. This method studies differences in the frequencies of particular allelic traits, namely polymorphisms from proteins found within human blood (such as the ABO blood groups, Rhesus blood antigens, HLA loci, immunoglobulins, G-6-P-D ...
The technology to test for DF27 was developed by Thomas Krahn, then of Family Tree DNA. This marker was discovered to exist among people who had taken part in the Human Genome Diversity Project . Richard A. Rocca made a pioneering study of DF27, which was published in 2012 in the article Discovery of Western European R1b1a2 Y Chromosome ...
Haplogroup H has been found in various fossils that were analysed for ancient DNA, including specimens associated with the Linearbandkeramik culture (H1e, Halberstadt-Sonntagsfeld, 1/22 or ~5%; H1 or H1au1b, Karsdorf, 1/2 or 50%), Germany Middle Neolithic (H1e1a, Esperstedt, 1/1 or 100%), Iberia Early Neolithic (H1, El Prado de Pancorbo, 1/2 or ...
In a March 2019 genetic study published in Science, three Celtiberians buried at La Hoya, Alava (in Beron territory) between 400 BC and 195 BC were examined. [17] They had high levels of north - central European ancestry compared to non-Celtic populations of Iberia. [ 18 ]

While these genetic variants account for only a tiny fraction - perhaps 0.1% - of left-handedness, the researchers said the study shows that this gene, called TUBB4B, may play a role in the ...
The study analysed 45 samples from southeastern Spain dating from the 3rd-16th centuries CE, all of which fell outside the genetic variation of preceding Iberian Iron Age populations, harbouring ancestry from both southern European and North African populations, as well as additional Levantine-related ancestry. 2 samples out of 23 dating from ...
Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia, from 25,000 years ago to present. The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), and European contact, after about 500 years ago.
