Agriculture emerged in several different places around the world not too long after the current interglacial began. At least some of those starts were independent, not inspired from others: certain agriculture originated independently in the New World.
But in the last interglacial, about 120,000 years ago, it apparently didn’t happen anywhere. At least I know of no evidence for it. And it’s surely true that there no technological civilization arose back then, because we’d find various kinds of lasting trash.
So.. but could there have been a try or two that didn’t spread far, didn’t prosper? False dawns? Some kinds of agriculture, like root crops, don’t leave a huge signature.
There might be hints in the genome. Assuming a decent human skeleton of the right vintage, we could look for signs of adaptation to agriculture. We know something about the genes that change in domestication syndrome: maybe we could find hints that somebody tamed wolves back in the day. One can even imagine an older kind of agriculture that was closer to instinctive: ants and termites farm without being very smart.
