As you allude to the lack of precision in the articles references, I am wondering about the "first modern humans some 85,000 years ago" who were just recently found to be making beads out of shells. Since the big question is yet, "When did modern behaviors such as speech and representational art first emerge and what was the relationship of the various Ice Age advances and retreats to human behavior?" This does represent an important find, however. Thanks for posting!
We humans were birthed by the last glacial period.
Big brains, language, cultural interlocks, and other survival traits are the stuff of ice.
In this there can be no debate.
