Where’s the science?
You might well ask. The science did a pretty good job of analyzing their remains, their injuries and their burial setting. But the rest of it is just PC academic BS and speculation. They don’t know who killed the children, or why (there is absolutely no indication it had anything to do with El Nino). Child sacrifice is not unknown in these Andean cultures, and went on over centuries. A really good book on the subject is “The Ice Maiden.” They don’t know why the children were buried the way they were. They don’t know the “socioeconomic group” of the children, and there is no way they could, nor do they know if those children were malnourished in comparison with their peers, or if all the children in that society were malnourished at that time.
