Research query on the A2 mtDNA haplogroup

 

Perplexity AI search.

Here's another search using Perplexity, where I asked the tool to collect journal articles featuring research with mitochondrial DNA from the A2 or A2d2 haplogroups. This was a bit better than my open ended query on Agnes Atherton O'Brien, as it returned several journal articles, links to FamilyTreeDNA's page on the A2 haplogroup, a link to Roberta Estes' 2013 blog on Native American haplogroups, along with one I didn't know previously that Blaine Bettinger also has a mtDNA connection to the A2 haplogroup.

The search concludes with "The A2 haplogroup is extensively studied in the context of Native American genetic history, with several high-impact journal articles providing phylogenetic, evolutionary, and population-level insights. Research on A2d2 is limited, but broader studies on A2 and its subclades offer valuable context and data for understanding its significance in ancient and modern populations".

This search did not locate the journal article I shared last month on Ancient DNA at Copán or the 2023 study on ancient DNA from Teotihuacan.
