I still keep reddit as a read-only resource, and yes, plenty of people still use it. There are niche communities that I sure do wish could hit a critical mass on the threadiverse, and the archive of advice and (mostly) human reviews of stuff are helpful.
That said, either it’s reddit or it’s me, but any community that’s even slightly large seems to have a lost a little thoughtfulness and vibrancy. The takes are more boring, the jokes more repetitive, and I run across others’ “goodbye overwrites” a lot more often than I thought I would, and generally in places where it seems like the original posts were genuine attempts to be helpful. Reddit is not gone, but it is reduced, and must eventually fade into the west.
As usual, it’s more the article (and especially the headline) than the science. Here is the Abstract of the study.
It’s much more about the specific burial and the inferences that can be reasonably drawn about South America before the introduction of dogs from the north 5k years ago. It references multiple burials with non-dog canids from across time periods in S.A., including at least one from about 4k years ago, as well as many other remains scattered in with human burials. It seems to build on existing theorizing that pre-Columbian practices might have changed more slowly than post. Then there are the statistical arguments. If you occasionally find a fox in human burials, based on the number of human burials you didn’t find, you can feel pretty confident that there were more foxes buried with humans.
