I don't see cultures mentioned anywhere in the article or the comment you replied to.

If mean that there are no differences in the genes that determine height across populations, that is incorrect. For example, the average male height in Pygmy populations is 5 feet, or about 7 inches lower than Cameroon's Bantu populations who live alongside Pygmies. We know there are genetic differences between Pygmy and Bantu populations that are specifically associated with height, and that average Pygmy height increases along with the percentage of Bantu ancestry (https://journals.plos.org/plosgenetics/article/info%3Adoi%2F...). Similarly, differences in height across European populations have been demonstrated to be partly due to differences in the hundreds of genes associated with height (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3480734/).

Fair, Pygmy genetics are minorly distinct. No other group is, and unless you're suggesting the urban Pygmy population exploded to account for these changes, it's irrelevant.

> Pygmy genetics are minorly distinct. No other group is

One group in all of humanity happened to have measurable differences in genes affecting height?

How does that explain the many other distinct "Pygmy" groups entirely separate from those in West Africa, such as those in the Philippines, who have genetic differences in growth hormones that cause them to be shorter (https://doi.org/10.1515/JPEM.2002.15.3.269)? "Pygmy" simply refers to one of these many groups, they are genetically and geographically distinct.

Pygmy groups show how absurd the claim that there are no differences in height is, but the same kind of variation has been shown within European groups on a smaller scale (consistent with the greater genetic diversity in Africa than Europe). We know that similar differences in genes that influence height exist, to a less extreme degree, across all populations. For example, males in both the Tutsi and Dinka ethnic groups average nearly 6' tall, despite living in areas where malnutrition is/was widespread and alongside other groups that are much shorter on average.

I'm genuinely curious where you got the idea that there are no genetic differences affecting height between ethnic groups/countries. Researchers have identified genetic markers responsible for the majority of variation in human height among Europeans (https://www.biorxiv.org/content/10.1101/588020v1), and shown that those markers vary significantly across European groups just as they do in Africa (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3480734/).
