Agriculture - Civilisation’s biggest mistake? I had a conversation with a guy a couple of decades ago. He was citing increased longevity over time. I pointed out that it was my understanding that decreasing infant mortality made up the lions share of that. — James Riley
You were completely wrong. Longevity is increasing - the same trend is seen where child mortality has remained constant. The data is pretty clear in this regard. We are undoubtedly living longer and longer on average and it isn't due to healthcare or healthier living as far as we can tell - because we are not exactly living healthier lives. It is a puzzling phenomenon and it is exponential in growth. You musty have heard scientists say that if you were born in the 2000's you're likely to live to 100.
It is probably something to do with a more species wide phenomenon that can be observed in other creatures from time to time. For some reason some creatures physically alter due to certain population limits. I wouldn't be at all surprised if humans acted in kind of the same manner (even though the mechanisms remain a mystery). Think of it like each human cell seemingly 'knowing' how to read the DNA coding and produce a fingernail cell rather than a neuron. Blow that up and think of each human being as a singular 'cell' with the species. Once a certain threshold is hit a new stage kicks in.
Given that CRISPR is on the horizon we will be pretty much able to live for ever - barring accidents and such. Diseases will be eradicated by CRISPR as will (almost certainly) what we currently regard as the human race ... we're going to recreate ourselves genetically and who knows what the results will be.
Note: It is okay to point out unexplained phenomenon. Examples of this are strewn through human history with the miasma theory of disease - which had some relation to mosquitoes living in humid climes. It took some time for people to figure out the it was the mosquitoes rather than the weather.
t brings to mind a sign in a bar just off the Shoshoni/Paiute Reservation. It said something to the effect: "We hunted and fished and crafted and sang and danced and had sex all day. We paid no taxes and the women did all the work. The white man showed up and figured he could improve on that." — James Riley
Generally speaking the lives of hunter gatherers was pretty brutal from what we can tell - and 'modern day' hunter gatherers are not exactly living to a ripe old age in perfect health (even though 'modern day' is not equated to actual prehistoric human lifestyles so not much of an argument there either way). There was likely a Golden Age of sorts where humans had plenty of freetime between basic sustainance, yet disease, parasites and general interhuman brutality were not exactly non-existent.
It could be argued that in our modern societies life seems harder than it is because we have it pretty easy for the most part - as in acquiring salts, sugars and fats.
There is also the issue of how our physical well-being has deteriorated from more physical life styles. Our diets have almost certainly impacted our physiological status ... how? We have limited data and not exactly a comprehensive understand of epigenetics and how the interplay of species and environment can shift in relatively sort spans of time.
The Birth of Inequality is a pretty well argued topic in anthropology. The issue of unearthing such matters proves difficult due to too many extrapolated fields of research that act contrary to each other rather than together (anthropology, psychology, neurosciences, biology, econmics, etc.,.).
