Connections to Teotihuacan

In March 2009, I had the good fortune to take a day trip to the historic site of Teotihuacan during a break from meetings in Mexico City. It was an amazing experience, and I was able to climb to the top of the Pyramid of the Sun. I'm not sure one can do that now (another thing I'm lucky I've done, along with climbing to the top of the Temple of Kukulcan at Chichen Itza).

Reading the study last week on ancient DNA at the Maya city of Copán reminded me to take a look at a study I had previously missed published in Human Genetics in October 2023 on mitochondrial DNA from ancient Teotihuacanos. Two of the individuals recovered at Teotihuacan had the A2d1 haplogroup (13-Lav and 14-Lav). See also this summary from Archaeology News (9 Jan 2024).
