Since human civilization sprung up practically as soon as the last Ice Age ended, I wouldn't be surprised if there were other small scale developments like this throughout the Last Glacial Period as well. There's almost 40 thousand years between ~50kya (the advent of behavioral modernity) and ~12kya (the end of the Younger Dryas period). Agriculture, on the other hand, would've likely taken a longer period of climactic stability which is why it only developed a couple thousand years into the Holocene.
