TheJadedOne: In that video he talks about how modern people tend to think that working conditions back then were objectively bad, but don't understand that those conditions (at least in voluntary situations, slavery and other forms of coercion is of course another story), as bad as they were, tended to be an improvement over what came before.
That really depends on who you look at. The conditions may have improved for some of the people on the lowest rungs of poverty but he is ignoring the misery (in some cases artificially created poverty to force people to work, see paragraph 3 under Parliamentary Enclosures
http://www.thelandmagazine.org.uk/articles/short-history-enclosure-britain), illness, and alienation that the I.R. brought to the workers. Was it worth it? Well, I certainly enjoy our modern lifestyle and technology, so I'm grateful to the people who went through the I.R. but I don't want to fairy wash the period.
TheJadedOne: Well, the typical European these days works about an average of what, 5 hours a day? So that's (compared to the industrial revolution work day you described) an extra 12-5=7 hours a day they could use improving their minds and skills if they so choose.
Here in Australia it's probably around 8 or so. I can't lump everyone in the same boat though since some jobs are more physically straining, others mentally. There's certainly time for some of us (i.e. me) but I know people who spend 2 hours commuting to and from work, and there is also an issue with people taking work home. There's a lot more to it than just lazyness, society is more complex these days in a lot of ways.
TheJadedOne: Not very much in forms we'd easily recognize today. They were certainly not having logic debates with each other. Maybe in the form of pack hunting tactics, animal tracking skills, and things like knowing that if Uga has his head smashed in and Buga's club has fresh blood on it, Buga is probably guilty. (Poor Buga, no due process for you!)
It's hard to justify calling the ability to imitate someone else creating a spear (so you too can then create one, and your sons can eventually imitate you) to be "logic and reason". Some of the other things they did, sure, but not imitation. And it's this imitation skill (and the random neanderthals that probably via trial and error "invented" and improved their weapons over time, along with a sort of evolution of "best weapons") that allowed them to get away with less strength (with the major benefit of not needing to consume the calories needed to sustain a greater muscle mass).
They were definitely more complex than that. People have spent some time trying to rediscover how they made a lot of their technology. There's a particular glue for holding spear heads, it's like a black tar, they have had a lot of trouble replicating it. Neaderthals had the more advanced technology, which surprised them since anthropologists used to assume they were rather simple. Also, the sort of communication required to organize large hunting parties, plus social structure and so on; it's the framework for modern thinking.
TheJadedOne: even the world's strongest or fastest man is humbled by chimps
You might want to rethink that:
"Humans can outrun nearly every other animal on the planet over long distances." And the human walking gate is
one of the most efficient of all animals. (Great apes, but not chimps, and bears use a similar walking gate in terms of how the feet work, but they don't walk upright which hurts their efficiency.)
In long distance running sure, and some African tribes use it as a hunting technique even today, but it is very situational. It only works in hot climates, terrain safe for running barefoot or with minimalist footwear, and on animals that won't turn around and try to gore you.
TheJadedOne: Also, I think you're kind of missing the point on strength. Yes, even early humans had to balance the benfits of having strength with the costs, and therefore did not have infinite strength. That does not change the fact that more strength is vastly more useful to someone trying to jam a spear into a bear than it is to someone trying to program a computer.
I'd say you are overvaluing strength actually :P I've spent a bit of time looking at primitive skills over the years, our local Aborigine tribes for example did hunt, but usually in (strength wise) very conservative ways: bird nets, fishing nets, boomerangs, and various traps. Hunter and Gatherer communities often emphasise the 'gathering': collecting grubs, moths, roots, nuts, grains etc.
There was some strange experiment regarding strength that happened not long after Western people first arrived in Australia. Because of Rousseau there were all sorts of ideas about 'the savage,' the one that applies here is the belief that they were physically superior due to the requirements of their lifestyle (running, hunting, fighting). They basically pitted the Aborigines against the Western sailors in some sort of strength gauntlet, and anyway they were surprised to find the sailors weren't weaker but actually far stronger, the Aborigines couldn't compete. Their lifestyle required less physical strength than a sailor's.
TheJadedOne: cooking to overcome weak jaws and teeth
That does not seem to be what cooking was for. Our jaws and teeth are
perfectly able to eat raw meat. Cooking has all kinds of benefits. The biggest appears to be that digesting meat that is cooked requires fewer calories, meaning cooked meat provides us more net energy. Some (plant) foods that can't be eaten raw either because we can't digest them or because they are toxic can be eaten if cooked. And cooking can also help if the meat is "off", preventing the eater from getting sick.
Again though logic is still necessary, he can't just power through it like a lion or animal with large powerful jaws. He has to cut, select, use tools etc. and cooking for most people makes the chewing incredibly easier. This guy has to be careful with his teeth, chew more, spend more energy etc. Without logic and reason our ancestors would not have survived, let alone thrived and learned to use the rest of the animal body to make tools and clothes with.
The other food our H&G tribes ate is roots. Our ancestors like Australopithecus were chewing machines, they lived on fibrous roots, they had massive jaw muscles and flat broad teeth. Later humans (and even modern groups in Africa) relied on similar roots but required cooking to even consider eating them since our jaws were so reduced.
TheJadedOne: That kind of makes sense. Hunter/gatherer populations can really only expand as much as the land will allow on a pretty much constant basis.
If they do not use really large stockpiles of food to smooth out all of the bumps, that would mean that they might be completely busy (eating/sleeping/working) when food is most scarce, but the rest of the time they have free time corresponding to how plentiful (easy to obtain) the food is.
Yeah it completely depends on the tribe and period in question. Some where doing it hard, while others lived at sustainable and comfortable levels.
