[Phithagoras]

I love nature documentaries, I'll have a look at that one!

I agree, lots of animals use tools in one way or another. Starting or even just controlling a chemical reaction does seem like a big step above mechanical methods though. I wouldn't really be that surprised overall if we eventually discover that H. Naledi or other hominids had some control of fire. I will be surprised if the Dinaledi site turns out to be the first evidence of it
