Race Differences



The term “race” usually refers to a particular group of people who have some visible physical traits, such as skin color, hair texture, facial features, or eye formation in common.

The truth is that no one really knows for how long the different races have been evolving independently, but it is generally believed by the scientific community that it would be necessary to go back a million years or more to find an ancestor common to all races.

Recent events in America (2014 & 2015), strongly suggest that those few who recognize the fundamental problems with race relations our nation currently faces, almost live in an intellectual vacuum. This is because most citizens throughout the United States do not seem to identify its most dangerous internal enemy: Racial and Cultural Discontent.  It’s apparent that if the public addresses this subject at all, it is to celebrate them as signs of a new and better America.

At no point, from the first basic attempts at classifying human populations in the 17,th  18,th  or 19,th centuries and into the 21st century have scientists agreed on a specific number of races of humankind; nor the features that should be used in the identification of races, or the meaning of the term “race” itself.   Experts have suggested an array of different races varying from as little as 3 to more than 60; each based on what they have considered distinctive differences in physical characteristics alone (comprising hair type, head shape, skin color, height, eye shape and so on).

One of the more popular divisions recognizes 3 major races, namely Caucasian / White, Asian / Mongoloid — (including Native Americans), and Black / Negroid; however there is no universally accepted classification for “race”; consequently use of the term “race” has been under fire for the last few decades.


The truth is, all men, of whatever race are classified by anthropologist as belonging to
a single species: Homo sapiens.  So the differences between members of the various human races are not great, even though they do not appear to be, nor do they act like members of the same species.  Regardless, it’s safe to say that “modern humans” have to date performed poorly, especially when considering interacting with each other.

In the prehistoric past, different races, and sub-races, probably avoided cross-breeding and behaved as if they were different a species. This concept is based upon the simple fact that “in nature”, animals that are no more different from each other than are northern Europeans and southern Europeans never breed with each other. You might argue that the Mule is an obvious exception, but if not for domestication by human-kind, horses would not mate with donkeys.

You might be somewhat surprised to learn that skin color is the least important way in which the races differ! Actually, races vary in skin color because of different levels of melanin (also called pigment) production. Each race has approximately the same number of melanin-making cells, but they differ in how productive the cells are.

Yep, melanin is the substance that gives the hair, skin, and the iris of the eyes their natural color (it also gives color to, feathers, and scales).   In humans, those with darker skin have higher amounts of melanin. By contrast, those with less pigment / melanin
have lighter or fairer skin coloring . . .  Frankly, anyone who has seen an albino African knows how trivial a difference in skin color is to race.


Color does have one biological effect tough: 3.5 times as much ultraviolet light from the sun passes through the skin of Whites as that of Blacks. Simply put, Lighter skin is typical to those who evolved in the northern regions while darker skin, which protects against the sun’s heat, developed in parts of Africa.



Another noticeable difference in appearance especially in many East African peoples include elongated limbs and bodies that dissipate heat more freely.   

As for Asians, who evolved in a much cooler northern climate; their bodies are typically of a smaller structure; they usually have thick, dark hair, with an eye fold that gives them their classic almond-shaped eyes — this characteristic is thought to have evolved so as to diminish glare from snow and ice not uncommon to the region.   Further, the virtual absence of facial hair on an Asian’s face indicates that back in the day when it mattered, condensation from a man’s breath would not freeze on his beard and therefore chill his face.  And no, Asians are not really yellow! See:



Not all racial differences are not so easily explained.  For example, for reasons unknown, all races do not smell alike. Blacks and Whites have strong, but differing smells, while many Asians have scarcely any smell at all. Koreans seldom have odor-producing glands in their arm-pits and Japanese have only a few.  Little wonder that when the 19th century Japanese encountered Europeans they found them rank smelling.

It’s a little known fact that Blacks / Africans produce identical twins twice as frequently as Whites / Europeans — who in turn have identical twins twice as frequently as Asians. And too, Blacks have shorter gestation periods than Whites or Asians. ‘Know what you’re thinking, but shorter gestation seems to be a characteristic of blacks that is independent of social status or access to medicine.

Alcoholism appears to strike the races at different rates. Asians (and American Indians to whom they are related) react more adversely than whites do to alcohol. More Asians than whites show an allergic reaction to alcohol and therefore may not drink as much and many American Indians seem to have a biological predisposition to alcoholism. Hence, the old western movie cliché suggesting Indians are more susceptible to intoxication than Cowboys. 

Curiously, Asians are twice as likely as Whites or Blacks to suffer from motion sickness.

Blacks are twice as likely as Whites to develop hypertension or high blood pressure.   One cause for high blood pressure among Blacks may be their relative inability to secrete sodium, so a salty diet would be more hazardous for Blacks than for Whites or Asians.

It has long been known that blood transfusions and organ transplants work best between people of the same race. In fact, until World War II, stocks of blood were routinely segregated by race. Classification by race was terminated when it was determined to be “politically incorrect,” however blood banks are beginning to re-institute segregation for obvious medical advantages.

Long the subject of coarse speculation; male members of the races do appear to differ in the size of their sex organs. The best data seems to have been gathered in a 1979 study that actually took measurements and found that popular myths are correct: male Blacks are better endowed than Whites and Whites are better endowed than Asians.  On a somewhat related note, Whites are estimated to produce twice the number of spermatozoa per day as Asians do.

Many attempts have tried to discredit the evidence established in a 1984 study which allegedly established the intelligence levels of the three primary races.   It reported the results of a survey of 20,000 human skulls showing that the average size of the brain case in a typical Asian is 1380 Cubic centimeters (cc); in Whites its 1362 cc; and in Blacks its 1276 cc. Perhaps nothing denounces this flawed theory more than a 1989 study which determined that brain size in humans have only a 0.3% positive correlation with intelligence.

In years past it was once universally accepted that races differ in intelligence, and too, the study of physical differences was once entirely respectable. Some 19th century biologists, though, hoped to find justifications for slavery, so can you believe it, not all were good scientists.      Today (2015) the best evidence suggests that races differ significantly only in such things as maturation rate, bone density, susceptibility to disease, and perhaps personality.

The bottom line is that any two humans; red, black, white, etc. are nearly 99.9% identical in terms of their DNA sequences.   On the other hand, during the past several years, a new type of genetic variation has been studied extensively in humans called Copy Number Variants” (CNVs), which are DNA sequences representing another important class of genetic variation and contributes a whopping additional 0.1% difference, on average, between individuals; so make that 99.8% identical.

If you are among the few who will admit there are still racial problem in America, you might consider reading the 1996 novel by Carl T Rowan: “The Coming Race War in America: A Wake Up Call” therein he warns that unless we act now, this country (USA) will by the end of the millennium have the same level of bloody racial strife that mired South Africa at the height of apartheid. In his chapter titled “How to Prevent Armageddon”, Rowan recommends a massive federally enforced disarmament program, speedy prosecution of racist cops, and early and massive interventions into the lives of underclass children— he suggests paying for this massive undertaking with the money now being earmarked for new prisons.


Before you simply dismiss Rowan’s viewpoint, you might first have a look-see at a few of his credentials: In 1961, Rowan was appointed Deputy Secretary of State by President John F. Kennedy. 

The following year, he served as a delegate to the United Nations during the Cuban Missile Crisis.  Rowan was appointed as the U.S. Ambassador to Finland in 1963.   In 1964, Rowan was appointed director of the United States Information Agency (USIA) by then President Lyndon B. Johnson. In serving as director of the USIA, Rowan held a seat on the National Security Council.      


Carl Rowan was a fair minded individual whose advice was persuasive and well-balanced – in other words he always came across as the voice of reason; in the very least he was a well-known and highly decorated journalist. His columns were published in more than one hundred newspapers throughout the United States. His name appeared on former President Nixon’s “political opponent’s master list”, now regarded as a back-handed complement. Not only was Rowan a 1995 Pulitzer Prize finalist for his commentaries, he is the only journalist in history to win the Sigma Delta Chi medallion for journalistic excellence for three successive years.  Before he departed those of us among the living in late September of 2000 he had served at a higher level than any other Black American in U.S. government history.

All you need do is follow the disturbing events from Ferguson, Missouri to Baltimore, Maryland to conclude that he was at least right to some extent. If then, surely now. The problems associated with race is a distributing factor and race diversity is undoubtedly here to stay, regardless of whether you are tolerant of the situation or a die-hard racist; let’s hope it’s not too late to deal with circumstance in a civilized manner!
