I admit I only skimmed those two references, but I don't see anything in either that suggests pig domestication taking place before plant domestication rather than alongside or after. Could you point me to where they talk about it?
Neither of the articles about pigs in China are quite so explicit to state that it occurred before agriculture, but there is a strong implication of it given it does appear to have occurred earlier. The relevant portion from the Hongo article (
https://doi.org/10.1093/af/vfab021) comes from the introduction:
"Pigs were domesticated independently in at least two locations of the world: in northern Mesopotamia by c. 10500 Before Present (
BP) and in
China by c. 8000 BP." Emphasis mine.
"In China, sedentary communities emerged by around 11000 BP both in the Yellow River Valley in northern China and the Yangtze River Valley in the south (
Liu 2005). These settlements provided the setting for the beginning of domestication of pigs, where some wild pigs took advantage of the anthropogenic niche and the “commensal” pathway proposed by
Zeder (2012) could have started." Here we see discussion about the early commensal pathway beginning among sedentary, but pre-agricultural communities in China.
"Wild millets were initially exploited in the northern region, where domestic types of millet were attested by
7800 to 7500 BP (see below) ... Rice (
Oryza sativa) was the main crop in the southern Neolithic, where the domestic form of rice was reported as early as
8000 to 7000 BP at Kuahuqiao 跨湖桥 in the Lower Yangtze delta." Emphasis mine once again. Here in we have dates for domestication of cereals in China.
The Rosenburg article I cited and the research at Hallan Çemi is far more explicit though that pigs were likely pre-agricultural domestications.
I like this! Any timeline with alternate civilizations in different areas of the world without successful civs developing is a must read on my end.
Though from your perspective given that the Mississippians did develop their own plant domestication why the ultimate failure in OTL?
Neat coincidence that you post this a day after I start with my much more difficult/implausible Alaskan cradle of civilization.
I think one of the biggest issues is that the EAC developed rather late. While the Calabash appears along the Mississippi by 7,000 BP, most of the rest of the complex doesn't seem to have been cultivated until closer to 3,000 BP. That doesn't leave a large window to develop the crop package or to build up much of a civilization. To get around that I needed to get agriculture to develop early than it did, for which the
Platygonus domestication is a big component. By having a domestic* animal early on to help alleviate food shortages and increase sedentism and population. Combined with the 8.2 kya event** causing some short term climate change, this stimulates the early agricultural development.
* Or rather, semi-domestic early on. I have a post planned out going into this in more depth late, but one of the leading hypothesis on early pig domestication is that it occurred by managed females that were allowed to breed with wild boars [1] as agriculture became more prevalent, this shifted to fully managed herds.
