The more I learn about animal husbandry the more I have to acknowledge that humans are and have been domesticating themselves. Which isn’t entirely as bad as it sounds, necessarily. But the repeated observation of multiple domesticated species is that they become more and more dependent on human interventions (antibiotics, deworming, artificial insemenation, fences, feed troughs, incubation or hand raising of offspring, interventions during birth to save the mother or offspring) Some of these are the unintended consequences of focused selective breeding for one feature at the exclusion of all others, but others are more insidious as the farmer is just trying to protect his bottom line here and there. And for the humans species I see the interventions all around us. We use antibiotics, we intervene during child birth to save the mother and child, we of course take medications for parasites, and many other ailments. We provide IVF and other amazing treatments. We live in cities we eat at restaurants instead of gathering the food or prepairing it. I do these things too, I believe at least one of my kids would be dead if we did not do these interventions. And if we needed to use IVF I wouldn’t hesitate, and all the other things and yet I can not help but clearly see that we are weakening our species genetic pool. And in time we will become more and more dependent on these interventions for more and more people. I don’t like the implications or the predicted outcomes.

This is a really interesting way of putting it. Definitely makes sense.

Coincidentally, a similarly-themed post that might be of interest. Sorry for the clunky link, the bridge is being a bit buggy.

Thanks for the link. Yes similar thoughts. A shame we can’t interact more organically note to post across the protocols.

I imagine everyone wants to take advantage of the improvements of interventions in health. It’s got a slow feedback mechanism though. Or at-least slow on human time scales. Maybe the future will look fondly back at this Bubble time period as when antibiotics still worked. When humans had all the inherited resiliance and the technology to assist health before the genes went to trash and disease caught up.

You can't have a properly functioning immune system if all you feed it is trash, which is what most are feeding it...

Feed it right & it'll work.

Yes, food is important. Exercise is important. Stress is important. Stimulating with exposure is important. But disease includes inherited susceptibility and issues. Most domesticated sheep for example have lost their resilience to internal parasites and the parasites have developed resilience to dewormers used by farmers. The sheep breeds that still have resilience to parasites are those breeds that have historically been in areas with high disease pressure (typically islands) and better if they are humid where parasites can thrive, without the use of dewormer, where their humans were too poor to afford or didn’t have access or were otherwise left to fend for themselves. Genetics and selective pressures will eventually play a role.

Just as well you have some of us not taking the shit then isn't it? 😂

Though it will need to be inherited from someone else, I'm not breeding.

😀 well if you had good genes and you use interventions your genes are passed on. If you had good genes and you don’t use interventions your genes are passed on.

If you have bad genes and use interventions your genes are passed on to the detriment of the gene pool. If you had bad genes and didn’t take interventions your genes are not passed on protecting the gene pool. This is obviously an oversimplification. But if you are refusing interventions you only improve the gene pool by being excluded from breeding through death or not being selected by a mate due to your weakness. 🤣 Choosing not to procreate is a trait that is maladaptive for survival of the species and is a characteristic that is constantly being selected against. Thank you for your contribution😅

I know all this rhymes with some gross oppression in history. But that doesn’t mean the underlying facts about a gene pools interaction with selective pressures aren’t true. 🤔☹️

Don't thank me too much, it's a big group of people & plenty are. 😂

People do realise that in just several generations there is sweet FA of them left in those descendants right? If people are looking for permanence they are going to be mighty disappointed...

Well yes and no. The simple model might suggest that after 5 generations (1/2, 1/4, 1/8, 1/16, 1/32) the generation is only 1/32 of the original. 1/32 doesn’t sound like much, But specific dominant traits which are expressed in you today because they are “dominant” would likely persist in them because they are “dominant”. Like brown eyes. Also some genes cluster because they are located closely on the chromosomes and so would inherited traits. And finally the other mathematical element of reproduction is present. Multiplication. With each generation the number of people which are my progeny increases. Assuming each generation is only fertile enough for replacement. I have two kids. Replacing myself and their mother. And they have two kids replacing themselves and their future spouses, etc (2,4,8,16,32) after 5 generations there are 32 people you would look at to determine if they had any of my traits, and I expect you would be able to find individuals in the 32 which would retain a cluster of the original genes especially dominant that are expressed in that generation. They would have my hair color or straightness, or smile etc. or they may “think” like me or something else. Because these traits weren’t really mine anyway, they were my great great grandparents before they were mine. And the fact that they are in us now is fact enough that they have persisted. Over the long term what persists depend on the selective pressures, which brings us back to the original topic. The multiplication and division gives us a lot of diversity in the 5th generation. What is the selective pressure determines what would be fit. In that generation which on the longer term overwhelms all the other math and you are left with what is fit. But if we keep using all the technological advancements that remove the selective pressures what was in the past selected for will be available to a smaller percentage of the population. But it’s exchanged at the cost of less death so 🤷.

I trust nature to do its job, it has proven itself, humans not so much...

Don't worry, it'll get its chance again, the idiocracy ensures it.
