Neon, there is so much I think you've gotten completely wrong and ignored but I don't see a reason for me to add anything new because there's is a lot of what your saying that has completely derailed from the points I addressed. You've made it sound like we are discussing something other than what I brought up. However, I understand you see things differently so I'll comment in order to clarify (for you and possibly others) why I said what I did, and why much of what you said is nonsense.
Much of what your talking about has nothing to do with the points I've made, they only discuss the same general topic.
For example, pay attention to the first quote in each of our replies (such as yours that is below).
Neon said:
Yes, the anatomy includes our skeleton, but it isn't exclusive to skeletons. And that isn't the point here.
Your shoulder breadth has to do with muscle or fat mass. Your bones do not magically get broader or narrower if you workout or become lazy, respectively. The average human is not born to have big bones or small bones. End of.
We are not arguing about the definition of anatomy. I know that the anatomy includes more than our skeleton, but that is totally irrelevant to my point.
As with much of what you said, the fact that you are making all these arguments, misrepresents my position.
I asked that you
"pay attention to our anatomy" to specifically consider the role the skeleton has to play. That same role it has to play includes the breadth of the shoulders. Regarding this specific point, I never mentioned anything about what makes shoulders broader or narrower; I simply said,
"Neon! pay attention to our anatomy!" in response to you saying,
"Having broad or narrow shoulders has nothing to do with your skeleton". Extra variables are irrelevant.
Either the skeleton does or does not have to do with shoulder breadth -by not addressing that, it becomes a red herring or sophistry at best. This pattern resonates throughout your post.
I know I'm repeating myself now, but the below is what I said in contradiction with your position.
1) Shoulder breadth does have to do with your skeleton.
2) Bones do vary in thickness, this is not abnormal.
3) Nutrition does affect height. Nutrition is necessary to grow/repair.
4) Other factors such as genetics affect height. Therefore a taller population in one place with poor nutrition may be taller than they otherwise would have been if they were a different population living in the same circumstances.
In regards to the African comment specifically, I tried to be clear as to why that's a terrible point. I tried doing it in layman's terms but I will try approaching this from a different angle now. Aside from the fact that there are countless very short Africans (due to malnutrition), not quite apart from the fact that many die due to lack of nutrition, you can't measure a dependent variable whilst using several independent variables. This relates back to point 4 which is above.
Neon said:
Who's talking about what's overrated and what is not? I am talking science here. And it plainly disagrees with "thick-bones".
Dude, are you punking me? Haha...Gym folks would obviously have bigger wrists because of their muscle makeup. Let's face it, they workout all the time. They eat a lot. Do you really expect them to have skinny wrists? Even a kindergartner would know that.
Science does not disagree with the variation of the thickness of bones. I used wrists as an example becasue there are many cases of thick wrist bones seemingly protruding from the skin of wrists, that indicate a clear difference in thickness of bones.
Neon said:
People with smaller wrists (the "small-boned" folks) barely have a BMI over 22. Newsflash, they are skinny. If they gain weight, their wrists would too (shocking, isn't it?). Can't believe that you fail to see or understand this very basic thing. :blink:
I refer you back to the point about scientific experiments regarding only having one independent variable.
Neon said:
Look, there are anomalies in humans. People are born with four legs for Christ's sake, but that doesn't mean that it's a regular occurrence. Same thing with big-bones. It happens (look up gigantism and maybe some 2 meter tall wrestlers), but it's a rarity. Odds are, the average fat or robust person you see in the streets has bones similar to any other person.
The variation in bone thickness in humans is not an anomaly, it's very common just as height variation is common. The only major difference is that the thickness of bones is less obvious than the lengths of bones. Nonetheless, they're both obvious. I suspect the problem in your reasoning is like saying "dogs come in different sizes but caterpillars don't". I think that you think that becasue it doesn't seem obvious to you, it isn't real.
Neon said:
Sorry, but that's totally false. If one can't grow without nutrition then all of the people in starving countries would be midgets. For the last time, we're only growing taller because of hormones (I commend you for acknowledging that btw, but you should really make it the quintessential factor).
I don't think you understand what nutrition is.
Nutrition:
"the process of providing or obtaining the food necessary for health and growth."
"food or nourishment."
"the branch of science that deals with nutrients and nutrition, particularly in humans."
If you don't eat anymore, you won't grow and you will die.
Neon said:
Look, I will not buy the whole nutrition thing and how it affects height. It's such an archaic idea - Something that your grandparents would tell you. I've grown out of it in my teen years when I realized that it was a farce (in which it is). Your height is genetic. It just is. I know, this sounds harsh and hopeless, but you can't do anything about it.
Africans are tall because of genetics and evolution. They live in a bushy grassland (and I'm only talking about those in Africa). They're evolved to be tall so they can spot predators (that's also one of the reasons why we started to walk upright).
So you think I've fallen for an old wives tale that my grandparents have probably taught me? What a ridiculous point.
Once again, I know that genes and evolution are a factor in height -I've explicitly pointed that out and consistently considered it throughout this discussion. Aside from all the pontification, by arguing about this, you're misrepresenting my position again.
Btw, the average height in African nations is rather short, this website goes through a few:

Neon said:
And who said that they don't eat anything? They eat in little quantities, but they still manage to be relatively tall. Their nutrition is still poor though, and you know this. So how did they magically be rather tall? Obviously, evolution plays a role here.
Once again, I refer you back to the point about scientific experiments regarding only having one independent variable.
Neon said:
Seriously? So what's happening to humans and how the environment is affecting us is not Darwinism or evolution to you? Lol, good joke.
Darwinism = "the theory of the evolution of species by natural selection advanced by Charles Darwin."
It does not mean "what's happening to humans and how the environment is affecting us"
If by saying that, you mean to bring up something to be considered when discussing Darwinism, then I've absolutely done that. I said that:
"The 11 cm jump in height is not due to Darwinian forces. A jump that big in the last 150 years in the UK has nothing more than an iota to do with natural selection." I said that fully considering what happens to humans and their environment. I also said that in full respect of Darwinism as a staunch Darwinist myself.
Neon said:
Nobody was talking about natural selection, btw. So don't call me ignorant on things that I didn't say. -_-
We were talking about natural selection.

Sharukinu said:
For example, in Europe in the last 150 years alone, the average height has jumped by about 11 centimeters. It is not due to some incredible Darwinian force favoring height -it's the mass consumption of food, sudden ubiquity of previously out of season foods, milkman, supermarket, icebox, refrigerator, microwave etc.
Whatever this genetically "planned" height is, it was clearly nowhere near being actualised by Brits 150 years ago. Research shows that our genes are constantly reacting to our environment and often behave opportunistically as well. In light of all the information out there, the argument should be about how much and to what extent nutrition affects height; it shouldn't be about whether or not nutrition affects height.
Then you replied to the above by saying:
Neon said:
That's true. It isn't really Darwinian per se. Well, in a way, it is. The environment and what we eat affects us (that's basic Darwinian evolution). For the umpteenth time, it's because of the hormones found in food nowadays. But your height is always genetic. If you ate a hormone-rich diet in the west and you come from a short family, you would hardly be 5cm taller than your genetically prearranged height. Can your children be taller as generations go by? Of course. I'm with you on that. And that's how evolution goes. It's gradual. It did take us a century to be taller.
I then responded to your above response by saying:
Sharukinu said:
With all due (or undue) respect, I think you don't understand how evolution works or you have some incredibly bizarre perceptive on British history. :victory:
When I talk about Darwinism, I'm talking about natural selection which is the only thing "Darwinism" means. Natural selection refers to the idea that certain organisms reproduce and increase/preserve their progeny more successfully than others, making their genes more likely to become prevalent. Organisms that reproduce and increase/preserve their progeny less successfully, decrease the prevalence of their genes. Therefore, genes that confer advantages/disadvantages in reproduction or the increase/preservation of progeny directly determine their own fate as generations arise over the course of time.
The 11 cm jump in height is not due to Darwinian forces. A jump that big in the last 150 years in the UK has nothing more than an iota to do with natural selection.
