I want to know the answer to the following question:
When did the use of agriculture begin it's spread?
All the background I'm provided with is that "Starting at the transition between the Middle to Upper Paleolithic period, some 80,000 to 70,000 years ago, some hunter-gatherers bands began to specialize, concentrating on hunting a smaller selection of (often larger) game and gathering a smaller selection of food.". Is that enough to answer the question?
Answer: no
