What this tells us is that the post 12900BP environment was quickly occupied by mobile bands of mobile hunter gatherers who followed the wildlife. This was expected, but it is nice to see conformation as well.
If our civilization disappeared today, the survivors would leave the same footprints. humbling to recall all that.
hunting and gathering was replaced by settled agriculture, but that demanded seed preservation and that was often tricky.
