I'll add domesticated animals, front and foremost the dog.

Live just wouldn't be the same without ya dog.



Ps. Alex if you're taking the "Coolgardie safe/cooler", you'd have to go back a long way. As for ice transport that would be a distance and transport tech. issue, people close to ice would have been utilising it prior to a lot of other basic inventions... Roman had ice shops, is one I found...

Other:
"...between 1000-2000 BCE—people discovered that they could make their food last longer by storing it at cold temperatures. The ancient Mesopotamians developed the most common form of storage called “ice pits” that evolved into “Yakhchāl” in Persia. These large dome-shaped clay structures had a hole on the top and a vaulted ceiling over the ice pit. Water from the ice would evaporate and cling to the walls of the dome to cool the air inside."

*The Artic Small tool tribes of Siberia may have been freezing fish and hacking them out 6000 years ago. I'd guess the tribes around the foot hills of Mount Kilimanjaro would have been storing food even prior to that.
