Climate. We know from ice cores that the climate prior to the current interglacial period wasn’t very conducive to crops. It was dryer and had less CO2. 180ppm be 260ppm pre-industrial area.

Lower CO2 levels meant that plants lost more moisture opening their pores and growth would be stunted.

Climate change is a big part of the puzzle, but for cases like the cucurbitaceae family in the Americas, it likely also reflects quaternary extinction events and social/behavioral changes in human populations, among other things. It's complicated and multifactorial.
