The Haplogroup H has to date 10 defined subclades, broken down by what is called coding region mutations. Of those 10 defined clades they create at current a phylogenetic tree of 267 coding region sequences as published (Loogväli et al. 2004). The subclades of Haplogroup H tend to show characteristic regional distribution. Thus, H1 and H3 are common in western Europe, having expanded after the LGM from the Franco-cantabrian refugium (Achilli et al. 2004; Loogväli et al. 2004; Pereira et al. 2005),
H1-16189C is beholden to a back mutation, making it neither truly H1, nor any of its children clades. H1-16189C, is the birther of H1b, among three others as highlighted in this graphic. As mentioned above H1-16189C is of highest count among the Basque population in the France/Spanish border. It's date of origin is considered to be 5,000 BCE making it akin to the Late Epipaleolithic and Early Neolithic cultures of the Iberian Peninsula. This age is known for early domestication of animals and agricultural farming.
