Having a little search of my own.
At the beginning of the Ice Age, we weren’t the only hominin around. The last vestiges of the long-lived Homo erectus and short-statured Homo floresiensis traversed the islands of Indonesia. The Denisovans populated Asia. And the Neanderthals tolerated the cold conditions of Europe. Though these species, our closest evolutionary kin, had thrived in the past, they all vanished from the archeological record in the midst of the Ice Age.
