But what do these haplogroups mean for genetic relationships between Teopancazco and other populations in ancient Mesoamerica? Álvarez-Sandoval and colleagues compared the Teopancazco DNA to groups in the Teotihuacan corridor, Oaxaca, and the Maya region and found that they were similar in their diversity. They also compared the ancient Teopancazco results with DNA from nine modern Native Mexican populations, which showed that the ancient skeletons were close to people from Tepehuan, Zapotec, Maya, and Mixtec populations. “These data suggest that the population of the initial phase of Teopancazco (Tlamimilolpa, AD 200-350) was composed mainly by local people and by foreigners from sites belonging to the Teotihuacan corridor to the Gulf Coast,” the authors explain. The fact that there was limited contact with other distant populations “suggests a lower genetic diversity during this time in comparison to the final phase of the Teopancazco history (the Xolalpan phase), characterized by the possible expansion of exchange routes between Teotihuacan and Mesoamerica,” they conclude. The researchers also did DNA testing on infants, which is the only way to tell from the skeleton whether the child was male or female, in light of the suggestion that some of these babies may have been sacrificed. In their sample, there were seven female infants and five male infants. More interesting than the balanced sex ratio, though, was the fact that the male infants showed greater genetic diversity. “This is the first time that hypotheses based on genetic data in relation to infant sacrifices in Mesoamerican populations are proposed,” the authors comment, and the data suggest that additional research may produce more answers to the question of child sacrifice at Teotihuacan. “Before our research,” the authors write, “comprehensive genetic studies aimed to better understand the multiethnicity in this site had not been carried out.” Their results show that, although Teopancazco was genetically diverse, its people came from areas and groups living close by. They are also the first group to suggest, based on DNA data, a relationship between infants and burial styles in the “termination ritual” in the transitional phase of the site.
It's very easy to get to Teotihuacan by bus from Autobuses del Norte. The ticket counter has a stylized pyramid. Tickets are cheap, and buses run every 15 minutes from morning to evening.
@@DanLikesToEat I believe the counter is by gate 8. Tickets are around 60 pesos each way ($3 usd), and you can do a one way - stay at a hotel in Teotihuacan for a day or two, then pay the bus driver when you come back. There's a fun restaurant called 'La Gruta' that's down the street behind the pyramid of the sun ... it's in a cave, and there are a lot of great mom & pop restaurants along the perimeter of the site. This is one of my favorite places to go - can you tell?
Interesting video Gringuito! Congratulations 🙌👊👍
Thank you so much José!! Muchas gracias ☺️
Esta piramide sale en la movie aliens Vs predator...
En serio??? Yo no sabia eso. Que chevere! Gracias amigo!
@@DanLikesToEat si ..

Thanks so much for the info, Brett! Super helpful!

@@bjones9942 that’s good advice! I hope to go back again one day and definitely need to check out the spot in the cave! So cool!
