@VLM, ice age ancestors needed big game. Small fish are a joke for sustained energy and nourishment, maybe as a condiment to the main meal of mammoth or aurochs.

Our "ancestors" really thrived for the most part of the very mega-fauna we helped extinguish.

Your sources seem to wildly differ from my sources regarding the bulk of ancestral homo sapiens evolution during the ice ages. Feel free to share them.
