In reference to their work ; it looks like they had a potentially statistically insignificant sample size of 40 , 20 malnourished with 20 control group, children?
As referenced the the following article;
http://garfield.library.upenn.edu/classics1985/A1985APZ5600002.pdf

>Our biggest obstacle was maintaining the stability of the sample of 40 children over 20
years. We improved the nutrition of the undernourished group, but were still ofttimes
challenged by their frustrated and angry parents..."

Where as other studies with larger sample size says the opposite result that intellectual disabilities are about 9x more likely for children that are malnourished. Ending with the following discussion " Moderate to severe malnutrition during infancy is associated with a significantly elevated incidence of impaired IQ in adulthood, even when physical growth is completely rehabilitated. " This study has a sample size of 136.

I always figured it was an environmental thing with female sexual selection.
Areas with less resources will have people that keep afloat, hoard resources, and plan ahead (higher IQ games) hoard more female sexual favor out of sheer survival instinct.
Areas with more local natural resources keep lower IQ folk more sated and less likely to play these hoarding games while mating with women in a natural sexual environment.

That's why the Japanese are tiny feminine people with higher IQ's than their genetic associates, native Hawaiians and north native Mexicans (Neo Hawaiian), both being larger and more athletic, one group (Tarahumara) being noticed for being one of the most durable marathon running people.

As for skin color, it's obviously vitamin D related. Darker skin means more UV rays needed to produce the same vitamin D quantity.
Essentially, going somewhere with difficult resource management raises your IQ, these areas tend towards having less UV rays (think colder areas with less resources), and that leads to lighter skin.

The exception are the inuit, except they get their vitamin D from fish, wish isn't that hard to get up north.
Vitamin D, btw, has a correlation with IQ in prenatal formation of African Americans. Meaning, their IQ goes up by 10 ish, if their mother took supplements during pregnancy. So, take that how you will.

Yes, I also remember how throughout the last 2 thousands years, the agriculturally rich areas of Western and Northern Europe had minimal problems with food security. With especially the Germanic and Nordic countries being notable for their rich soils caused by the massive meandering mountain chains carving up half the country. Along with their often thick black/boreal forests blanketing the entire country side. Both of which have always been conducive to only the most fertile land in the world, land like the great PLAINS in North America and the Ukrainian STEPPE.
Surely food scarcity played an almost non-existent role in European politics, especially over the last 100 years. Infact, I'd say that it definitely didn't have an outstanding influence on Germany's participation in the first or second world wars. There definitely wasn't multiple famines/food crisis in post war Germany, and they definitely didn't directly help Hitler rise to power. Hitler also didn't have securing food as one of his primary motivations for going to war, why would he? I, and most Americans aren't directly descended, on both lineages, from European famine refugees, no sir.
Ok no more, annoying sarcasm. Do you genuinely just not know any European history/geography? It's alright if you don't, but be honest, most people can't even point it out on a map. If you try to lie and say yes, then I am sorry, but you have terminal retardation. Most of Europe has depleted soil from the last ice age glacial recession, with it being so bad for the nordics that they need to put lime into the soil for anything to grow, due to its natural acidity.

"In February 1939, Nazi leader Adolf Hitler told a group of Wehrmacht officers that food was the most important problem facing Germany.[9] The solution proposed to alleviate Germany's dependence on food imports was to create more Lebensraum (living space) for the German people by conquest and colonization." Europe was likely the least productive place for food in the old world, relative to population. The northern soil is unusable, with the English soil being naturally depleted and water logged. The French are some what well off, but it is spread out in tiny patches across the country. With Mediterranean soil being not very useful in northern climates. Italy is also somewhat self-sufficient when it comes to food, but the soil isn't made for high output grains and oats. Every large river is notorious for large seasonal flooding, which turned its otherwise rich river banks and deltas into useless sludge. Russia is a barren waste land with only small pockets available for agriculture, interspersed between regions that turn into multi meter deep mud holes for months every spring. The only area with high quality soil is Ukraine, but check the famine list and see how that turned out for them.
Almost every war fought in mainland Europe had some element involving food. Leading to all modern borders being in someway determined by food. This, and the fact Europe is scarce in almost every other resource, leads to an extremely hostile environment where genetics are favored that prioritize problem solving, long term planning, and memory.
Not only is the soil horrible, you are far enough north were you have to spend months preparing for winter, or you die. You now have to produce twice the amount of food given half the amount of time, with soil, that is more often then not worthless.

It does not seem to be primarily based on skin color. An average IQ of 85+ in an underdeveloped country can reasonably be assumed as heading towards 95+ because of the Flynn effect. For example, Sri Lanka is dark brown, yet has an average IQ of 88 according to Lynn. However, you assume that in nature, the average IQ is comparable to the standard British mean, which does not seem to be true and was likely not true in Britain, either, until a recent moment in broader history. IQ likely fluctuates. Today, the average IQ of countries which independently invented agriculture is ~83. It's likely that the Sahel and Ethiopia were among them. However, according to Lynn's studies, these places all have an average IQ <75. That's quite the difference.
The problem is that it's hard to determine the objective factors to help us closely approximate it for a period long past. Preference towards r-selection and earlier sexual maturation seems to be correlated with intelligence among animal species, and sub-Saharan Africans somewhat follow this trend. However, this is not enough to explain the vast discrepancy. Intelligence is a very expensive trait, so a species is as unintelligent as it can be. The critical question is why the entire species does not have an average IQ of ~70 (why it came to be, that is). A commonly given explanation in these circles is a cold climate, but polar aborigines are not the smartest humans on Earth. The temperate climate zones have the highest mean average IQ, but the median is not much better- South African, Argentinian, American, and some Central Asian aborigines all have average IQs <85.

Low IQ groups have historically notable individuals, because IQ is a normal distribution- it's about the total sum. The ancient Middle East was crucial, but it stagnated. The only civilisation in history that has never stagnated is the West- not at its peak anymore, but technological progress has been constant for around 800 years.

Sub-Saharan Africa is dominated by an extremely dense and bountiful rainforest stretching almost 5000 miles form Gambia to Ethiopia, all they way down to Angola, Zambia and Tanzania. Rainforests are the easiest biomes to subsist in, with little need for group interaction beyond immediate family. Are you hungry? You go walk 10 feet into the forest and grab whatever nutritious fruit/animal you can find. Agriculture and husbandry is never needed. We know a system similar to this occurred for most of Africa's history, with only a handful of civilizations forming, all for short periods of time.
South of this great rainforest is primarily steppes which are decent for farming, and especially good for livestock grazing. To the south east you have fertile land dominated by cambisols and luvisols soil. And to the north of this you have what most people think of when they imagine Africa, the Serengeti. Which is easily the most animal nutrient rich area on the planet. With the remaining Sub-Saharan land being more rain-forest, savannas, or small patches of desert. It is debatable whether Africia is the the most fertile continent.
Africa is the most naturally interconnected continent. It contains multiple extremely long rivers that are continuously navigable for hundreds to thousands of miles. It also has hundreds of smaller rivers and tributaries that effectively make the the inner Sub-Sahara as navigable by water as the United States (the most connected). There is only one catch to this, the entire continent below the Sahara is effectively blocked off from navigation between it's rivers and Oceans, with most river mouths ending in massive waterfalls or intense rapids. This acts mainly as a geographic defense against outsiders.
The African continent is, and has for centuries, been considered the most resource abundant area in the world. It contains an estimated 30% of the world's remaining minerals. Africa is by far the easiest land to naturally survive in.

I suspect the thousands of years of relatively contained local European warfare, ensuring no dominant hegemony on the continent, until the Romans, is the intelligence crucible responsible. Hegemony always leads to cultural, genetic, and economic stagnation with an inevitable millennium lasting collapse. This also correlates with the weakness of the Chinese relative to the Japanese, come around the 1900s.
Genuine tribe/clan/nation sized conflicts, selects for whole group increases in intelligence. You can't just have your commanders have higher IQ, as IQ increases combat effectiveness down to the grunt. The US military ran a number of tests measuring effects of IQ in deployed soldiers during Vietnam. They found that anyone with an IQ lower than 80 was not capable of completing mundane day to day operations, and had causality rates several times higher than people closer to the mean. To this day they refuse to allow anyone with an IQ below 80 and have tailored their enlisted entrance exam to correlate higher with IQ than any other test that isn't itself an IQ test (with it being used as a standard for conversion). They do this so they can refuse entry for anyone in the bottom 20% of the population, without running into the legal troubles associated with using IQ tests for selection.
If you think about it, their findings on low IQ enlistees implies that a traditional opposing force with an average at least a standard deviation lower then yours, will be decimated. While one with a standard deviation higher than yours, being nearly impossible to beat, at least in a standard fight. One could use this to explain the insanely disproportionate effectiveness of various forces throughout history. I think the best example of this would be the gulf war and most of Israel's week long wars with several middle east countries.

I agree, and more broadly, complex social systems create positive selection pressure for intelligence. It becomes self-reinforcing. However, this still leaves open the question of their initial emergence and the difference in their effects. In western Africa/the Sahel, there were large-scale conflicts and imperialistic expansion, and no hegemony that united the entire region. Yet, according to Lynn's studies, this region is not noticeably more intelligent than its neighbors.

East asian countries in general have higher soil quality. You're reasoning falls apart when u consider that harsher environments encourage more hunter-gatherer lifestyles which favour brawn over brain, combined with the hotter climates and brain development and evolution are severely stunted. Asians are just the natural result of abundant resources and good climate.
