How does your genetic inheritance, culture and history influence your health? Biological anthropologist Lara Durgavich discusses the field of evolutionary medicine as a gateway to understanding the quirks of human biology — including why a genetic mutation can sometimes have beneficial effects — and emphasizes how unraveling your own evolutionary past could glean insights into your current and future health.

      A lot of people have this channel hate-subscribed just to brigade it. You see it a lot on topics like feminism, culture, politics, identity and some others.

      @Errant Cognition Because you need her size to detract from the validity of her talk.

    • Brendan Morin

      May 19, 2020 at 4:53 pm

      Errant Cognition what has she talked about that has literally anything to do with weight?? And I’d love to see what you look like lmao, bc I know for a fact no decent looking person would so insecure that they feel the need to body shame a woman on the internet XD plus I’m sure she’s contributed more to humanity in the last MONTH of her life than you could ever hope to contribute in your whole life

      @Aaron Rosenberg because obese people shouldn’t be lecturing about health

      @Brendan Morin Entertaining of you to conjecture lol, you have no idea what I do. Most fit people hate fat people. All they do is make excuses and pretend it’s not their fault.

    In addition to the beneficial side-effect that Lara mentioned, there’s two other salient points on why a bad gene might not be eliminated through evolution:
    (1) – There is nothing natural about humans anymore; medical science kicks natural-selection in the crotch and lets people with horrible conditions survive, which isn’t bad, but it also lets them have biological children which _is_ bad because humans are selfish idiots who don’t think of the right thing and do what they want (like having a biological child knowing full well they have bad genes that can put a horrible burden on their children. So complaining about natural-selection is specious. (No, medicine isn’t new, humans have been using it to keep people alive for thousands of years, so you can’t argue that it couldn’t have had an effect on evolution.)
    (2) – As she touched on at the end, Jews are (in)famous for preferring to “keep it in the tribe” as they say and procreate with other Jews as much as possible, hence the gene pool is shallower than the general population which exacerbates and proliferates genetic conditions.

    So the key to the survival of the human race is to date out your race. 😉

      Also white people will extinct as we have weaker color genes. We should not force or brainwash anyone to do anything relating to making a family. It is about what they want, prefer or feel.

    I have a genetic disease, it causes degeneration in my eyes, in general in my central vision, but don’t is macular degeneration, according with the specialists in my country — Brazil. According with them, is degeneration of cells “cones e bastonetes” — in my language.

      Inbreeding is huge part of human history, from all areas of the world xD how else do you think our population has grown from only around million in parts of the ice age, to almost 8 billion today haha

      So because of her size, you discredit the content of her talk? Please, refute her talk about “health” point by point.

      May 20, 2020 at 12:33 am

      @Aaron Rosenberg “im broke af, but you should listen to me for financial advice”
      “i dont take care of my health enough to not be fat, listen to me for health advice”
      “im not a model, listen to me for modeling career advice”
      “im not a scientist, but listen to me yap about how the universe was ‘created’.”

      @FractalPrism i have a hard time to control my eating habits, so I can’t know anything about evolution

    • Aaron Rosenberg

      May 21, 2020 at 4:18 pm

      @FractalPrism
      Her PhD is in biological anthropology.

      She teaches university courses on evolutionary medicine, primate evolution and behavior, human biological variation and female reproductive physiology.

      She’s lectured undergrad and grad students at Harvard, Boston University and Tufts University, and has earned multiple awards for teaching excellence.

      You can find all this out on your own. But you pretend that she’s giving a talk on how to lose weight so you can feel good about discrediting her.

      Something is very wrong with you. But that’s your personal burden to bear.

    I remember reading a long time ago that the best way to extend the length of the human lifespan was to delay reproduction until in your 40s. Yes, there would be more problems for a while, but over time genetics and evolution would weed out the weaknesses and select for the strengths if we let it happen. The problem is the morality of letting it happen.

    So squalid inbreeding causes Tay-Sachs disease, but increases IQ and protects from TB.

    This is just part of evolution and you, the ten generations before you and the ten generations after you are just a insignificant blimp on the evolutionary path of the human race.
