After spending hours going over paperwork, I was ready to sign the lease of my new San Francisco apartment. The property owners, Bill and Virginia, a delightful Caucasian couple well into their 80s, were just about the nicest and sweet couple you’d ever meet. As we wrapped up, Bill walked us out the apartment and as we approached the the top of the driveway, Bill stopped and asked me and my six-foot-tall Chinese house mates:
Bill: I met a lot of Chinese people in the past.
[As soon as I heard Chinese, I thought: Here it comes, Bill's 81-year old ass, after decades of tumultuous race relations is going to drop the chink bomb]
Bill: How did you three get so tall? Everyone else I know is tiny.
Me: It’s the milk…
Bill didn’t mean any offense, but it lead me to think: Yeah! Why are Asian’s so short?
In the story of creation, it’s not like Asians landed on double-zero in a game of height roulette. After all, whether you’re Yellow, Black, White or Brown we all share the same lineage. When our Homo Erectus ancestors left Africa, it’s not like the tall ones decided to go to Europe and the short ones to Asia. Instead, the reason is most likely due to the environmental and human encounters to follow.
Cases for natural selection as illustrated by the Peppered Moth lend credence that we are the products of our environment. The black peppered moth, commonly found in England, thrived at the onset of the Industrial Revolution. As factories and industry rose in England, the ensuing pollution led to a biological advantage for dark colored moths which were now camoflouged from predators. The natural advantage, or ‘selection’ eventually allowed dark colored moths to flourish throughout industrial England.
So what’s unique about the Asian environment that could explain the vast difference in average Asian heights?
YouTube blogger DeStorm (I could have cited an academic, but where’s the fun? His take is at the 5:35 in the YouTube video below) posits that the reason African-Americans being bigger, faster and stronger is rooted from some Darwinian aftereffects of slavery. Plantation owners and slave owners needed slaves for heavy labor, so therefore drove the demand for stronger, faster, and bigger slaves to work the plantations.
As for Caucasians? Scandinavians are just about the tallest peoples I can think of. From the little bit of European history I know, the Viking invasions and conquests in Continental Europe meant that these tall and strong Vikings intermixed and intermingled with the rest of Europe as their conquests brought them in contact with the natives of modern England, -France, -Germany and -Russia and spreading their tallness throughout Europe for centuries to come.
What’s up with the Asians then? When you look at the last 5,000 of Asian history, Asia was neither invaded by giants nor practiced any institution (like American slavery) that instilled eugenic side-effects for height. Instead, Asia maintains a long and agriculturalist history. And what did Asians farm? Rice! While a staple in the world’s food supply, when compared to cereal crop’s oat and wheat native to Europe, rice pales in comparison in the amount of protein per serving. Protein, a crucial compound in biological growth, isn’t as rich in rice as other cereals.
Ultimately, the reason why Asians are shorter boils down to two environmental factors. First, Asian’s just never intermixed with any taller peoples (at least not until the yellow fever epidemic 
). Second, Asia’s farming history and dependence on rice meant that Asian’s took in, on average, less protein than any other peoples. Sure, every now and then, you get an outlier like Yao Ming but I’m speaking in general here. But as to why I’m tall? It’s the milk
If you have a completely different theory, please feel free to voice your opinion freely in the comments.

Yawn!
Dude, I am taller than you. It’s not the milk. I was a formula baby. It’s not the rice. I ate a ton of rice. It is not because I am northern. My parents are 100% chinese from the south. I am not bad at math. I am horrific at math. My hair is not straight. It’s curly.
What an idiot.
I am Hmong (they’re a hill tribe from Southeast Asia) and I’m the tallest girl in my family (5’6″). It’s mostly based on genes. My maternal grandfather is taller than me, (5’9″ maybe) and my grandmother is probably 4’9″ maybe less. My paternal grandfather is pretty tall, and my grandmother is also short. My dad’s younger brother is about six feet, and one of my mom’s younger brother is also six feet. My mom is 4’11″ and my father is about 5’4″. So a lot of it does have to do with genes. Two of my brothers and I are the only tall ones in our family. So yeah, a lot of it does boil down to genes.
Hi,
I’m a member of a new start up company called Asian Crew Inc.
Our Mission: At Asian Crew Inc., we fight stereotypes, one obnoxious statement at a time. We got tired of the conventional, cutesy, and frankly racist T-shirts meant for Asians on the market, so we decided to make our own. No more karate kicks, math problems, or Confucius quotes. Just some in-your-face statements printed on high quality clothing. So if you love who you are but hate being labeled, you came to the right place.
We would appreciate it if you wrote a blog post about us!
Thank you for your time!
Height mostly is genetic, with there some environmental-dependent selection as well. One component has to do with tropical climates and a shorter body being more effective at dissipating heat. Obviously the post was written tongue in cheek about a cliche stereotype. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3048786/
Well it also has a lot to do with culture/selective breeding. Different cultures value different attributes. For instance Africans and Vikings valued physical dominance and had a warrior dominant culture. Many Africans groups had a much longer hunter gatherer culture than other societies so not only did the most physically dominant warriors have the breeding advantage, their very survival depended on being physically adept.
Asians on the other hand were more agricultural, domesticated livestock earlier, and enacted a complex civilization earlier. So very early on in many Asian cultures, being physically strong was actually looked down upon because it was the mark of a laborer, hence it was fashionable be pale and to grow long nails. The wealthy and scholarly were at the top of society while laborers were at the bottom and with it came very high mortality rates.
Nice blog and I enjoyed the video. I just wanted to add some facts: 60-80% of height is determined by genes. This is a result of studying twins. You are right that diet is important, as well as general health. Like others have pointed out the theory about slavery having a positive eugenic effect is suspect. There may be a marginal effect there. My pet theory is that there are positive new traits that come from genetic mixtures and Africans in the new world were thoroughly mixed with other Africans as well as Europeans (not as much as people tend to think). This might explain the physical prowess of us black folk. I’m Jamaican and it is well-known that we are faster than the average human. Faster, even, than our fellow Africans. Let’s just remember that while race marks a difference it is not always a very significant difference. And there can be significant differences within racial populations (which in the end are rather arbitrary). After all, Africans are among the tallest (some tribes in Sudan) AND among the shortest (pygmies). Also if you look at average height data over time, whole nations can get significantly taller or shorter over just a few generations. Peace . . .
why do people think black people are strong and asians are short im half japanese half manx (isle of man) and im 6’5″ tall at age 15 and the strongest in my school im not black and just because im asian doesent mean im short
Great man, and the video is awesome.
It’s great when random people without any sort of credibility can spew this nonsense. Anyone can theorize about stuff, but it takes actual research to do it well. It becomes clear that the author didn’t bother to do any right when he says “our Homo Erectus ancestors left Africa”. Yep, that’s a good one.
Of course, it only gets better when he cites a random YouTube blogger who spouts out some slavery eugenics junk. If this hypothesis were right, then we should witness a significant difference between the speed, power, etc. of African-Americans vs. Africans, because African-Americans were subjected to this slavery eugenics effect. However, there’s not any evidence to suggest that African-Americans are significantly different from Africans in these traits, which debunks the idea of a slavery eugenics effect.
Furthermore, while protein intake might account for some height variation, it is not enough to account for the height disparities between Asians and the rest of the world. Consider Asian-Americans assimilated to American culture (i.e., they generally have adopted the American lifestyle). Are they generally significantly taller than their Asian counterparts because they eat like Americans? No. Human growth depends on human growth hormone, and just the mere intake of more protein does not thereby supply the body with more HGH.
You’re forgetting that Northern Chinese and Koreans tend to be tall (6 ft +) because of the grains and wheat (bread basically) in their diets. And yes, having rice as the majority of your diet kinda sucks – little to no protein!
Although you speak truth from your opinion and I’ll respect that, what was said here was very, very general and superficial.
Yeah they’re random assumptions that myself and my future land owner made. You do have a point though in the logic you mention. Are Asian’s really shorter, or is it just perception?
You are very much way off the mark on this, so I might suggest never talking about this again.
There are many short Asians in Asia. But at the same time “Asians” are not short..
You might have some probable points in terms of diet but everything else are just wild assumptions you are throwing out there.
But this is just not your kind of topic.
