What an odd set of notions, it sounds rather improbable. Which comes first, control of fire or large brains. Control of fire doesn't seem right. Obviously the answer's there in the archeological record but nobody's screamed eureka yet.
the alternative is a diet change, a bunch of proto-hominids having enough peace and quiet for a few millennia to select what grew locally and to arrange access to easily-digested meat. Maybe they learned to fish in a place abundant with marine or lake food, that would do it. They'd get a lot more protein and energy from a fish than from a wildebeest and the fish takes seconds to catch, not hours. Raw fish is far more digestible than raw wildebeest.

Our hominid ancestors could never have eaten enough raw food to support our large, calorie-hungry brains, Richard Wrangham claims. The secret to our evolution, he says, is cooking
By Rachael Moeller Gorman

Richard Wrangham has tasted chimp food, and he doesn’t like it. “The typical fruit is very unpleasant, the Harvard University biological anthropologist says of the hard, strangely shaped fruits endemic to the chimp diet, some of which look like cherries, others like cocktail sausages. “Fibrous, quite bitter. Not a tremendous amount of sugar. Some make your stomach heave. After a few tastings in western Uganda, where he works part of the year on his 20-year-old project studying wild chimpanzees, Wrangham came to the conclusion that no human could survive long on such a diet. Besides the unpalatable taste, our weak jaws, tiny teeth and small guts would never be able to chomp and process enough calories from the fruits to support our large bodies.
Then, one cool fall evening in 1997, while gazing into his fireplace in Cambridge, Mass., and contemplating a completely different question—“What stimulated human evolution?—he remembered the chimp food. “I realized what a ridiculously large difference cooking would make, Wrangham says. Cooking could have made the fibrous fruits, along with the tubers and tough, raw meat that chimps also eat, much more easily digestible, he thought—they could be consumed quickly and digested with less energy. This innovation could have enabled our chimplike ancestors’ gut size to shrink over evolutionary time; the energy that would have gone to support a larger gut might have instead sparked the evolution of our bigger-brained, larger-bodied, humanlike forebears.
In the 10 years since coming on his theory, Wrangham has stacked up considerable evidence to support it, yet many archaeologists, paleontologists and anthropologists argue that he is just plain wrong. Wrangham is a chimp researcher, the skeptics point out, not a specialist in human evolution. He is out of his league. Furthermore, archaeological data does not support the use of controlled fire during the period Wrangham’s theory requires it to.
Wrangham, who first encountered chimps as a student of Jane Goodall’s in 1970, began his career looking at the way ecological pressures, especially food distribution, affect chimp society. He famously conducted research into chimp violence, leading to his 1996 book Demonic Males. But ever since staring into that fire 10 years ago, he has been plagued with thoughts of how humans evolved. “I tend to think about human evolution through the lens of chimps, he remarks. “What would it take to convert a chimpanzeelike ancestor into a human? Fire to cook food, he reasoned, which led to bigger bodies and brains.

And that is exactly what he found in Homo erectus, our ancestor that first appeared 1.6 million to 1.9 million years ago. H. erectus’s brain was 50 percent larger than that of its predecessor, H. habilis, and it experienced the biggest drop in tooth size in human evolution. “There’s no other time that satisfies expectations that we would have for changes in the body that would be accompanied by cooking, Wrangham says.
The problem with his idea: proof is slim that any human could control fire that far back. Other researchers believe cooking did not occur until perhaps only 500,000 years ago. Consistent signs of cooking came even later, when Neandertals were coping with an ice age. “They developed earth oven cookery, says C. Loring Brace, an anthropologist at the University of Michigan at Ann Arbor. “And that only goes back a couple hundred thousand years. He and others postulate that the introduction of energy-rich, softer animal products, not cooking, was what led to H. erectus’s bigger brain and smaller teeth.
So Wrangham did more research. He examined groups of modern hunter-gatherers all over the world and found that no human group currently eats all their food raw. Humans seem to be well adapted to eating cooked food: modern humans need a lot of high-quality calories (brain tissue requires 22 times the energy of skeletal muscle); tough, fibrous fruits and tubers cannot provide enough. Wrangham and his colleagues calculated that H. erectus (which was in H. sapiens’s size range) would have to eat roughly 12 pounds of raw plant food a day, or six pounds of raw plants plus raw meat, to get enough calories to survive. Studies on modern women show that those on a raw vegetarian diet often miss their menstrual periods because of lack of energy. Adding high-energy raw meat does not help much, either—Wrangham found data showing that even at chimps’ chewing rate, which can deliver them 400 food calories per hour, H. erectus would have needed to chew raw meat for 5.7 to 6.2 hours a day to fulfill its daily energy needs. When it was not gathering food, it would literally be chewing that food for the rest of the day.

Anyway, we didn't evolve here, we evolved in a constellation far away from here. The spaceship has finally sunk to the core of the planet so we will never find it. It was probably our spaceship and not a meteor that messed it up for all the dinosaurs.

How many great philosiphers (sic) have there been who could not spell? Dare I say more than a few? But they did not mince words, they gave meat to their thoughts by proving themselves.
I converged two threads into one. A meeting of the minds as it were.
Ain't I good?

Sadly, I think it is for the moment. With the improvement in healthcare and the technology the bring to the task there is no biological imperative to cull the weak genes.
Take eyesight as an example, I'm damn'd near the limit to be registered blind but with specs and contact lenses I can see as well as most.
Under natural conditions I would not survive - even five hundred years ago I can think of no jobs I would have been able to do to support myself. Even if I had been supported on charity I would never have married because I could not have supported a family - my best chance would have been to join a monastery but that, unfortunately, is a celibate profession.
So bad genes are no longer being taken out of the pool with the result that the pool is not longer improving - the race is no longer improving.

A fascinating book based around how the human race evolved when they took to the sea's edge after the forest dies during a bout of global warming.
