    This is framed like 80 generations is a small number, but that’s huge. Culture and civilization moves so quickly that even 3 generations ago life is barely recognisable. I can’t even imagine what life was like 40 generations ago.

      Many people don’t realize that the amount of change our culture goes through in a lifetime is unfathomable historically. Before the 1800s it took a good decade for news to truly travel around to everyone in a region, and that was considered timely if it happened at all. Farming, hunting, homemaking, war, stayed exactly the same for dozens of years at a time and changes were usually made abruptly due to conflict before stagnating again.

        The French tried to impose “metric” time way back in the day. Even they learned that was a bad idea and quietly dropped it. The solar system seems to prefer it’s base12 time.

        I think it maybe helped give rise the the saying: “The French follow no one. And no one follows the French.”

    And if everyone of your ancestors was unique (so no inbreeding) 80 mothers ago there would had to be 280 = more than 1.2 septillion people on the planet

        No I’m talking about the amount of ancestors in the 80th generation back not the total amount of ancestors. It doesn’t matter how many children each set of parents had for that number.

    Yeah only 2 generations ago, LGBT people were considered mentally ill. 4 generations ago women were considered unfit to vote. 8 generations ago about half the US though it was OK to own slaves. It takes a while for ideas to die out. That’s why US elections turn out the way they do.

      Humanity isn’t progressing uniformly forward like this. Lgbtqia+ people were considered normal part of society by various cultures. Also Magnus Hirschfeld was an advocate for lgbtqia+ people a hundred years ago. Slavery has been transformed into modern slavery because the western world has found other, more concealed ways to force people into labor. Ideas may die out, but they will pop into people’s head again and again.

        And yet discussing progress in this manner can be a confort. All that you said was true… But what the person you replied said was also true. Two generations since fertilizer or two generations since we locked in Malthusian anarchy[please note I do not espouse Malthusianism]. Three generations since the worst war known to man and three generations that did not experience that kind of war. Glass half full, glass half empty. It’s correct to question the myth of unstoppable progress thru which you can just kick your feet up and relax. But equally is it important to keep perspective remember that, yeah, eight generations ago chattel slavery was a bonafide institution and four generations women were unfranchised. Things get better and they get worse. We make progress and it is wiped away. We still keep trying.

          The American people are pretty fickle. It won’t take long for them to become unhappy with the Republican party. Of course once that happens and you and I are celebrating “Yay! We got rid of the fascists!” they’ll be going “Hmm… These other guys are pretty uninspiring. Maybe we should try fascism again.”

          * There’s a big asterisk here that this is all predicted on elections continuing unabated. Which is not a given.

            And when the Democrats put up the same fascist policies in continuation of the status quo and refuse to defend those who find themselves targeted by Republicans, you will “hold your nose” to vote for them and cry at anyone who refuses to fall in line and do the same; in fact you will actively work against their efforts to build up power in resistance of both parties just because it won’t immediately pay off and you’re too brainwashed to believe in any power but the two-party system’s power. And then your party will lose anyways and take another step rightward in response. I know you people, we’ve done this whole song and dance before.

          This has happened before. Even after Abu Ghraib Bush Jr won re-election. Even after Iran-Contra the Republicans won re-election.

          But the fact is that they do not have the answers. They can only take things for themselves, and hope that people give up.

      That’s also assuming you’re the first born of the first born of the first born, and so on. And the further back you go, the more individual kids the average mother is likely to have. After all, you had to have like 12 kids just so 3 of them would make it past 9.

      So your greatx12 grandmother might’ve started having kids at 15, but she still might not have had your ancestor till years later.

    That’s not a well-founded assumption. The average age of first birth was only 21 as recently as 1970. Go back a few hundred years and it’s way younger than that. Many women throughout history became mothers as soon as they were able (right after the onset of puberty). Many cultures had rites of passage into adulthood for boys and girls of that age. There was no such thing as adolescence.

      As the other commentator says, medieval Europe was mostly early twenties. Studies of stone age remains suggest a first birth age average of 19.5 and contemporary hunter gather societies have a comparable average. Sexual activity generally begins earlier, during adolescence, but the most “reproductively successful” age for beginning childbearing has been shown to be around 18-19. Also, this age at first birth isnt “Average age of a child’s mother” as many women would have multiple kids over their life, so the average sibling would have a much older mother at birth than the firstborn.

      Its important to remember that puberty has shifted massively since industrialisation, "menarche age has receded from 16.5 years in 1880 to the current 12.5 years in western societies". So the post-puberty fecundity peak, that use to happen 17-19, when women are fully grown enough to minimise birth complications, now happens at a disressingly young 13-15. Not only is this a big social yuck for most western societies, but it’s reproductively unideal, because of the complications linked to childbirth at that age.

      In Western Europe at least back to the early medieval period it was common for anyone who wasn’t nobility to have their first child around 22. The younger you are the more likely you’re going to have serious (fatal, back then) complications. It was the nobility that was marrying off barely pubescent kids.

        Could we say (for no other reason than I’m stoned and it sounds good) the rough average mother-age is 18-ish? Then there would be roughly ~110 mothers since Jesus cheated and respawned for our sins.

          No idea, I’m not as read up on that. It would shock me if it was significantly different just because risk of death from complications is a hard biological line the younger you get, pre-modern medicine.

            There are definitely cultures who have practiced polygyny to get around this issue. Some still do today, for example in many different countries in Africa where people still practice a pastoral life.

              I don’t see how polygyny gets around the issue of risk of death from pregnancy.

              Polygyny would get around the issue of men getting killed.

                  Edit: This first point was wrong, but the second point still stands.

                  Polygyny wouldn’t solve the aforementioned problem if we suppose that the birth rate of men and women is roughly the same. If one man has many wives, some of whom even die, then several other men won’t have any wives.

        High maternal mortality meant that having more than about 7 children per woman was rare. Total fertility rate was about 4.5 to 7 in the pre modern era. Population growth was low due to infant and early childhood mortality though.

        If you start having children at age 12, you can have a child every year and reach 7 children by age 20. Without contraceptives, people weren’t having such large multi-year gaps between children like we do now.

          Based on my own genealogical research, the trend I typically saw was 6-8 kids, between 18 and early 30s, about 20% of which died. Plus consider that some of those will be sons, and some daughters never become mothers, 25 is pretty spot on for the average age for a mother-to-mother generational gap.

      Maybe 23 would be a better average, but even if wvery women in your line gave birth at 12.5 that only doubles the other. And its fair to say not every mother would have been a first child. Also many still would have been born later than 25, so it probably evens out pretty well.

    I was thinking that it’s now 81 mothers ago, but then I got distracted by the fact that there was no year 0AD and now I’m thinking that roughly 80 is good enough.
