Sweating.
Seriously.
The most significant difference between humans and our primate cousins is a full-on overhaul of our onboard cooling and heat-management systems. We traded body fur for subcutaneous fat, and could suddenly dump waste heat by evaporation at a maximum rate of 750W!
Along with bipedal running, active cooling enabled early humans to shift ecological niche and become phenomenal endurance hunters. Able to hunt large prey in African temperatures at midday.
This single adaptation also brought with it a significant side-effect.
Once we had this new dangled liquid cooling we could also support a larger brain capacity. Large brains generate a lot of heat, and would cook themselves with old school passive cooling.
So sweating was the key adaptation that allowed us to shift out of the forest. And turn into intelligent cooperative hunters. And that in turn brought language, tool use and the rest.
