Another attempt at a broad question I asked here earlier. My aim here is to build another cradle of civilization from the ground up, in an area that never did (for fairly obvious reasons) and in an area that could serve as a sort of connection point between the Old World and New World.
For most the part I am getting together a rough idea of what I need to do and where I want to go with things but I am have trouble getting the initial setup going, this is where the plausibility factor might be kicking this entire idea in the groin.
To get to the point are there any plants in the interior of Alaska, specifically the Yukon River basin, that could serve as a founder crop to serve as the catalyst for further plant domestication and ultimately sedentary civilization. I haven't been able to find much, not sure if its due to a lack of resources on the topic, a lack of knowledge on my part as to where to look or a lack of said plants in the region.
I mean the area could certainly provide a decent supply of food for locals, especially with proper agricultural practices, winter preparation, advanced/complex food preservation techniques, etc. For instance Alaska does produce oversized record breaking vegetables due to loads more sunlight during the summer.
