Either they read my thread or came up with the same wording and pretty similar mechanic as me (which wouldn't be that surprising since I think it makes sense as far as real life history).

"...the basic techs, such as farming, animal husbandry, mining, hunting, etc., would have to be unlocked via "eureka" moments. Farming would be unlocked after enough foraging/planting. Mining after enough gathering of metals. Animal Husbandry after enough experience with animals able to be domesticated.
Once the population gets a "eureka"(basically inevitable, when you have the people working on hunting, or foraging, or raising animals), the respective technology will be unlocked. Technological progress will automatically made by the people as they continue to harvest or hunt, as they refine abilities and discover new techniques. "
""eureka points" are what determines if a technology is discovered by the populace. Eureka points come from a variety of sources...
1. From citizens carrying out tasks, like farming, hunting, building.
2. From buildings, temples (the eureka points tend to go towards religious techs), libraries (more general eureka points), courthouses tend to create eureka points for government, cultural buildings create eureka points which tend to go towards cultural techs.""
