Negroid hair

[Agrippa]

The frizzletop functions like a sun helmet, under the frizzy hair the air can circulate better and sweating can be stronger, is not as problematic as well as with the straigh-wavy hair.

So its a heat adaptation to prevent the brain from being overheated.

The brain is the human weakness, thats not so problematic in the colder climate, but in the heat its very important to keep the brain cool and even the size of the brain might correlate.
Furthermore the black skin protects from UV rays but black gets hot faster in the sun so they need a better transpiration and the "sun helmet" (short-frizzled hair) they have and not long hair which would make the head sometimes even hotter...

Comments?

The head heats up itself from the direct action of the sunrays. But living in the bushes this wouldn't be needed. Perhaps I'm missing something..

Moistly heat. Moistly Savannahs, lake regions might be the habitat of the first Negrids imho.
In such regions you get as much or even much more problems with the heat than in the open desert.
In the open desert extreme transpiration wouldnt be that good as well.

I think it's a plausible theory. By the way blacks do get sunburn too, this is something I had no idea about until a few years back when one of my classmates complained about it and she was actually redder under her brown skin; her skin was also peeling off. Of course their sun tolerance is way better, but still. I find it quite interesting.

On the other hand, what would be the advantage of really straight hair?

Strange.. she must be some kind of mixed type. The [pitch black] Negroes from Nigeria that I've seen over here, under the strong heat of August they get a blue purplish tone. Their skin also looks more like leather than proper skin (in that it looks thick).

On the other hand, isn't straight hair a Mongolid trait?

Then, how come the indigenous inhabitants of the extremely hot and moisty rainforests of South America haven't lost their much straight hair.

Sure these natives are Mongolids, but they have inhabited those areas long enough to have adapted to them.

Savannahs can get extremely hot, almost as desert-like environments.
Some theories claim that Congoid and Khoisanid types emerged from humans living in non-forested areas (savannahs) and mongolid types in cold steppes while caucasoids emerged from a mixed biotype region.

South American natives don't need frizzly hair simply because the weather is warm and moist, not warm and dry. With the air being hot and moist there was no need to develop frizzly hair. A similar adaptation can be seen in body hair: both mongolids and negroids lost most of their body hair since it became unnecessary.

It's still "tanning" though, isn't it? I mean, even though the really dark skinned africans do tan, one way or another. My classmate was from Trinidad & Tobago; she had quite dark skin too.

As for the thickness of the skin, yes, that's a fact. Probably that also is a heat related thing. Oppositely fair skin tends to be thin most of the time.

No, it isn't?!

I noticed that none of the Congo races portrayed in this attachment has straight and long hair. Does this mean that all those black mtv / hollywood starlets use chemical methods / hair extensions or can it also point to white admixture?

Both is possible, both is usual. Most use fake hair or perukes tough. Just look at the males with their oftentimes short and frizzy hair or shaved head and the women with the long and oftentimes straight hair.
Even mulattoes dont have such straight-wavy hair usually if the Negrid part was pure.

In Africa you can see this in Aethiopids (f.e. Tutsis) already which are able to have longer frizzy hair, the typical fully Negrids have just this "sun helmet".

Then, how come the indigenous inhabitants of the extremely hot and moisty rainforests of South America haven't lost their much straight hair.

Sure these natives are Mongolids, but they have inhabited those areas long enough to have adapted to them.

Well, they dont lived in this region long enough and the moisty Savannahs of Africa look different and are more open, expecially the lake regions.

As important is the fact that the straight Asian hair is a specialisation and it seems that it is much more difficult and less likely to develop frizzy hair after such specialisation in which most genes for frizzy hair, which might have been present in the old stratum, are lost and the pure variant for straight hair is the rule.
In my opinion, though thats just a personal view, straight hair is more robust and doesnt need so much care and is better in extreme cold, but still looks rather healthy.

As for the Indianids of the tropics, well, they used another way, they bacame more thick-set piknomorphic and good transpirators. There was enough water and this tendency was already present in the Asian populations.
They never were sprint hunters and fishers on open lake regions like the Negrids, which couldnt use this way of adapting (rather paedomorphic-pyknomorphic) with the exception of the Bambutids which combined both and the Palaenegrids being intermediate.

The typical Negrid (Sudanit) is no forest type but for the open Savannah and lake regions in my opinion.

This really dark leather skin is not typical for all Negrids, but mainly for Nilotids and some Sudanid groups. Now the interesting thing is, a hybrid of Nilotid-Europid turns out to be less Negroid and lighter than f.e. a Sudanit hybrid most of the time.

This would speak for what already Eickstedt said, that though they are the darkest race of the planet they are not fully typical Negrids with a small amount of Europid genes-tendency oftentimes.
Though there are extreme types going in a typical Negrid direction under the Nilotids as well.
This Nilotid has longer hair whereas the woman has extremely frizzy hair (rather "fil fil") though her other features (prognathy, chin, breasts, body type etc.) are not extremely Negrid like in many Nilotids.
Both pictures are from Bakers "Race".

This is interesting because at the moment I can´t remember only one popular Negress with natural African hair. I guess it must be some sort of inferiority complex. Most probably they are subconsciously worried about the fact that Negro males are strongly attracted to white women and thus they are trying to look more European.

[Agrippa]

Well, darker skin color is not such a problem like the hair, because the typical frizzy hair looks just rather unattractive. It was never selected because it was attractive, but because it was a necessary cooling system and the longer hair was rather disadvantageous at least for a certain, for the evolution of Negrids, important time.

For males its "ok" but for women which have in most other cultures long hair which is a sign of feminity (wich some exceptions for short time periods) its a serious problem and competitive disadvantage which they try to outflank by using fake hair.

Its interesting that in many border regions between extreme Negrids and Europids-Aethiopids and with "higher culture" the indigenous Negrid fashions tried to prolong their hair and weaved various artificial products in their hair.

Its like it is with the extremely small Mongolid eyes, I dont know of any case in which this feature was culturally accentuated over a longer period of time. Rather frizzy hair is one thing, this extremely short "sun hat" hair another which wasnt that popular.

Certain features didnt came up because of sexual selection and weren't not too popular especially if "alternatives" were present like people with bigger eyes, longer legs (Mongolids) or longer hair, narrower nose etc.

Europids had the luck that they were not in the extreme situation being forced to overspecialize in a certain direction, probably except extreme depigmentation which might constrict to a certain degree if its about certain climatic regions as well.

The only style Negroid hair looks good in (except very short) is "processed" in one way or another: dreadlocks, rasta, etc. Sensible people usually have one of these styles; "Dreadlocks" can look really stylish too, they don't have to look punk. The other most common black hair I see around here is defrise, that's putting permanent chemical (as in having a perm) but instead of rolling it to make it wavy, straightening it. The problem with that is, because blacks usually have very, very frizzy hair and it's really thick, when the hair is straightened a) it gets a really weird reddish tone and b)it doesn't have any movement. Just sits there like a helmet.

In a natural way they can't get rid of their "sun helmet".

And if Negrids have dreadlocks they usually have to use artificial hair parts if they are typical Negrids of course...I dont speak about people like Bob Marley

[Rusalka]

As for Mongolid hair, or Asian hair; it differs quite a lot from the Caucasian straight hair. Caucasian straight hair is usually the thinnest compared to wavy and curly but Asians have the thickest hair around and it's sraight as no 'white' hair would be. My hair is straight but it's not dead straight, Asians have that special straightness. Apart from that there is one extra ingredient, if you will, in Asian hair. Forgot the name now, but they used to put the essence of it on breads. Was it Phleg who told me this? I think so.. I think what adds the thickness to Asian hair is that. It's also the reason why Asian hair wouldn't lighten easily. It's so hard to lift the color and the only highlight they can get is usually a dark auburn (unless they risk burning half their hair.)

Well yes, that's evolution for you.

What I meant by dreadlocks was something like this:


This style can also be with much thicker locks, which looks very nice on women. I don't think it requires any extra hair, rasta and serious dreadlocks do though.
