The lower testosterone is a result of xenoestrogens and other environmental toxins babies and adults are being exposed to at higher amounts. However, total testosterone isn't what matters, it's the free testosterone that matters. The only relevant study I saw on this was that Indians from India had statistically higher total testosterone compared to Indians born in the UK (like 15% higher), but the freetestosterone was closer.

Higher intelligence is what makes humans the dominant predator on the planet. Higher intelligence is what created the study of war, firearms, martial arts, its responsible for creating concepts like Special Forces. Higher intelligence is what allows a 140lbs man to have no fear of apex predators like the Great cats. You need to rethink your core concept.

Less facial forward growth in domesticated animals might be a poor example.

It has more to do with the toughness of your diet than anything else really.

The time period is too short for those kind of changes.

More likely is the massive hormonal disruption caused by chemicals in water/food/air.

Yeah that and all the estrogen they put in the tap water

I’m not so sure about it being an evolution thing. It could be more acute.

That said, I’m more knowledgeable about hormones than 99.x% of the population. I’ve studied it constantly for the past 5 years. I had to go on TRT around that time.

You have to understand the mind/body connection. The mind causes physical changes in the body. Pain for example. Your brain can make it severe or completely turn it off in the right circumstances. I believe the domestication or pussification of men has led to changes in androgen levels.

I can’t prove it, and neither can anybody telling you it’s soy, etc, etc, but my personal experience tells me it’s true.

Keep in mind lower T levels or higher does not exact the same result from person to person. Men vary at 20 years old as far as their male traits go. Deep voice, muscle mass, motivation, etc. it’s doesnt necessarily follow measured leveled of testosterone. At the cellular level our bodies all respond differently.

You can't compare us to chimps. We're a whole different species. We can't even interbreed. Dogs can and do mate with wolves.

Try looking at a german shepherd skull, irish wolfhound etc. Those don't seem very neotenous either, despite being domesticated.

This has been one of my favorite theories for years.

Just remember this: while neoteny and human domestication will continue to play an ever-larger role in a developed and peaceful world, it is the cues of danger and violence that trigger the primal instincts governing sex.

In fact, if all you relentless beta/alpha categorizers want a truly useful dichotomy, just ask: is my behavior domestic, or primal?

It's called gracilization and has been observed in all tamed species, as well as human bones even since the forager-settler transition occurred. The soy era is just the peak of this process whereby society's institutions (media, schools and learned behavior) play the role that the death penalty and ostracization played during the history, i.e. removing the non-docile strains from the gene pool. Of course eating crap food, not lifting, breathing poison that passes as air in the cities, sitting on a chair 8+ hours a day and so on play a role as well.

Domesticated live stock is selectively bred to be tame and easy to handle. A side effect of that is the neoteny you speak of.

As far as humans go the reasoning is much more difficult to understand and there is most likely many contributing factors such as the increased levels of plastics in our food, little to no factors that remove the sick and weak allowing them to go on and reproduce, societal factors, and much much more.

I think neoteny plays a part, but there are several other factors. Plastics are one of the biggest factors imo.

Human beings have always been comparatively neotonous since we diverged from our common ancestors with the chimps; that comes with higher nueroplasticity and intelligence. Most species learn near all what they need to know when they’re young so keeping that brain structure throughout your whole life has the benefit of boosting your ability to learn throughout your whole life. Most creatures also have an instinct to care for their young; having everyone more resemble their young could perhaps be helpful for building more mutual care and social cohesion (spitballing a bit but it seems reasonable).

I’d wager that rather than selective pressure the introduction of phaetoestrogens and other chemicals to our diets and the increasingly sedentary lifestyles are the main contributors to the recent emasculation of men, with electronic devices near the testes being a small but contributing factor to fertility declines especially.

I’m personally more interested in the increased feminization of men’s correlation with the rise of collectivist and left wing policies since by and large females tend to be more oriented towards the collective while men tend to be more individualistic.

I stopped on the second paragraph. Artificial selection from a cherry picked population sample (foxes) has very little to do with the fact that humans self-domesticated with their immense abundance (humans getting less developed), or neoteny.

Whenever this topic comes up, I never see any studies done on women's hormone changes, if any, through the years. That would be useful information for those who claim that it's soy, or plastics, or birth control chemicals in our water supply.

Correlation =/= Causation.

Its key to remember this is a hypothesis, and should be seen under such a context for it does not ascribe causation and does not even remotely touch on it, or mechanistic factors underlying any such changes. Worse this retarded video linked on disney princesses talks absolutely nothing about human biology. If you want to learn about that there are free courses online from academic institutions.

In terms of known differences, differences in population groups, those exist in the arena of racial demography. This is the realm of Eugenics which is modern day biology.

Human populations are:

regressive to a population mean

intelligence is also relegated to the population mean

muscle mass, height, build, bone density, muscle fibers, intelligence, energy systems are also regressive to a population mean

Some things for those who're new. We have what are known as "transposable genes" which fall into the new field of epicgenetics, meaning the output of hormones in response to an environment can alter our development, our aptitude, our height. We are even altered in gestation to prime us to respond to environmental stimulus. Famines often cause the children born of such a generation to retain more energy, becoming fatter in times of plenty.

In terms of falling testosterone, the obesity epidemic, the pseudo science being shilled by the overtly corrupt AMA in relation to dietary information is largely causal for this. Not withstanding the deleterious effects of digital gaming, social media on the male psyche and body. By definition, the Western life style that is the average, norm is a regression on our physical health and worse, this is likely by design as a methodology of population control. "Bread and circus for the masses".

In terms of the video linked about disney princesses, that should be blatantly obvious as to why an audience would respond to a younger demographic with enlarged facial features. In terms of character design the head is typically enlarged for the basic fact of communication, ergo larger facial features are much easier for an audience to read, be emotionally empathetic with. Plus disney targets a youth demographic, so a relatable character is obviously going be regressed on.

There's more to address in terms of Eugenics, but the OP don't seem to have a clue, and few in TRP I would assume freely research into this area.

OP search “Pottenger’s Cat’s” on youtube.

It's related to fat and obesity. Fatty tissue transforms testosterone into estrogens. That's all If you get in account that the more prosperous you become, the fatter you get, the T levels falling should be no surprise Check it up

The real reason why this is happening is probably a combination of factors. Neoteny occurs during selective breeding for docile traits, this coincides with lower androgens. Selective pressure resulting in neoteny. However, secondary-neoteny could easily occur due to a reduction in androgens not due to selective breeding for docile traits, but because of chemical impacts on the endocrine system. If androgens are persistently malaffected, I would expect neoteny to begin expressing itself within a few generations.

With recent discoveries in epigenetics, where chemical impacts on a species can be inherited without affecting the underlying genetic structure, consistent exposure to artificial estrogens lowers androgen production. Via epigenetics, the trait of lower androgen production is being selected for widely, and within generations begins neoteny.

Neoteny is a symptom of a very serious problem, it's just unlikely that it is the result of active selective breeding by the female. Chances are, artificial estrogens in plastics are destroying men, and causing secondary-neoteny of the species over time via epigenetic selection.

Hahaha, this is female projection.

The increased usage of soy in any perishable edible product might have something to do with it.

My diet in university was generally appalling, pot noodles (instant dry noodle snack where a major ingredient is.. you guessed it, soy) I was also no stranger to drenching any rice dish that came my way with copious amounts of soy sauce.

Finally I think the shit injected into livestock which is sold worldwide, coupled with their diseased and unhygienic living conditions may have contributed to the lack of lead in a mans pencil.
