Vaguely interesting discussion...
... but I'm thinking no-one watched the linked documentary!
For the purposes of their topic, they spoke about Australopithecus, Homo Erectus, and Modern Humans. I kept expecting them to refer to the latter as Homo Sapiens. They didn't, but I'm pretty sure that's what they meant. These three very broad categories were enough to show the three major differences in diet and corresponding fundamental body differences: Australopithecus had teeth and gut suitable for mashing and digesting raw plant matter; Homo Erectus had teeth more suitable for tearing raw meat and had a larger brain from the better nutrients; "Modern Man" developed a gut better at digesting cooked food and an even larger brain from the even better nutrients. This was the program's main thrust.
I suspect if they had another hour to fill, they could have explored how Homo Sapiens developed cooking, including looking at which Neanderthals experimented with it. They could have also spent more time looking at what cooking does to food. But they didn't.
