The bacteria in the human mouth – particularly those nestled under the gums – are as powerful as a fingerprint at identifying a person's ethnicity, new research shows.

Scientists identified a total of almost 400 different species of microbes in the mouths of 100 study participants belonging to four ethnic affiliations: non-Hispanic blacks, whites, Chinese and Latinos.

Only 2 percent of bacterial species were present in all individuals – but in different concentrations according to ethnicity – and 8 percent were detected in 90 percent of the participants. Beyond that, researchers found that each ethnic group in the study was represented by a "signature" of shared microbial communities. @nacionalismoidentitario

Oral bacteria create a 'fingerprint' in your mouth

Racial and ethnic variations in serum testosterone levels were investigated among a large sample of male Vietnam era veterans. Based on geometric means, significant average differences were found between 3,654 non-hispanic White and 525 Black individuals. This could explain some of the race differences in the incidences of cardiovascular diseases, hypertension, and prostate cancer. @nacionalismoidentitario https://pubmed.ncbi.nlm.nih.gov/1621259/

Asians and Africans consistently aggregate at opposite ends, with Europeans intermediate, on a continuum that includes over 60 anatomical and social variables. These 60 variables include brain size, intelligence, sexual habits, fertility, personality, temperament, speed of maturation, and longevity. If race were an arbitrary, socially-constructed concept, devoid of all biological meaning, such consistent relationships would not exist.

Mongoloids, caucasoids, and negroids can be distinguished on the basis of obvious differences in skeletal morphology, hair and facial features, as well by blood groups and DNA fingerprints. Forensic anthropologists regularly classify skeletons of decomposed bodies by race.…In certain criminal investigations, the race of a perpetrator can be identified from blood, semen, and hair samples. To deny the predictive validity of race at this level is nonscientific and unrealistic. @nacionalismoidentitario https://www.amren.com/news/2010/05/statement_on_ra/

Statement on Race as a Biological Concept - American Renaissance

A brief reply to attempts to discredit the concept of race.

A common libtard myth that evolution only happens on a very slow timescale (and therefore human races cannot possibly exist).

In reality, "human evolution has sped up in the past 40,000 years and has become 100 times faster in the past 5000 years alone" (source).

Divergence / speciation / subspeciation isn't something that magically happens after a certain time period.

Greeland sharks are 2 million years old but have diverged into zero subspecies.

Most dog breeds have only existed since the "Victorian Explosion" and vary wildly in phenotype. They would be classified as distinct subspecies if they existed in the wild.

Recent research suggests that some race/ethnic groups, particularly non-Hispanic Black subjects, are predisposed to a reduced VO2max by way of muscle fiber type. Combined with insufficient physical activity, these characteristics place non-Hispanic Black subjects at an increased risk for obesity and other adverse health outcomes when compared with other race/ethnic groups. The purpose of this review was to suggest a model for explaining how skeletal muscle fiber type may contribute to reduced aerobic capacity and obesity among non-Hispanic Black subjects. Our review indicates that metabolic properties of type II skeletal muscle (e.g. reduced oxidative capacity, capillary density) are related to various cardiometabolic diseases. Based on the review, non-Hispanic Black subjects appear to have a lower maximal aerobic capacity and a greater percentage of type II skeletal muscle fibers. Combined with reduced energy expenditure and reduced hemoglobin concentration, non-Hispanic Black subjects may be inherently predisposed to a reduced maximal aerobic capacity compared with non-Hispanic White subjects, thereby increasing the risk for obesity and related metabolic diseases. @nacionalismoidentitario https://pubmed.ncbi.nlm.nih.gov/25739558/

West Africans and their descendants dominate competitions in which their muscle fibers are best put to use (sprinting, football, basketball, etc) while they suffer in competitions in which Caucasians and Asians dominate in which muscular endurance is needed (weightlifting, powerlifting, distance running).

World’s Strongest Man

Muscle fiber typings play a major part in the winners of these competitions as does limb length. Generally, the winners of the World’s Strongest Man (WSM) are more stocky and have shorter limbs which translates into more power generated since the distance is shorter.

A White man has won the WSM competition every year since its inception. It’s always a Northern or Easter European who wins these competitions. The Russians and Slavs are known for their crazy squat programs, and muscle fiber typing is the reason why. They are able to generate more power than those with fast twitch fibers which translates into domination in strength-based competitions.

The same thing is noticed in powerlifting. Caucasians and Asians dominate. I’ve seen some incredibly strong East Asian powerlifters, and the reason is they are shorter and stockier with shorter limbs. More power is able to be generated with the shorter distance and Type II fibers which allow these populations to excel in these types of competitions. @nacionalismoidentitario https://notpoliticallycorrect.me/2016/08/17/muscle-fiber-typing-hbd-and-sports/

Biological differences exist in the body composition of Blacks and Whites. We reviewed literature on the differences and similarities between the 2 races relative to fat-free body mass (water, mineral, and protein), fat patterning, and body dimensions and proportions. In general, Blacks have a greater bone mineral density and body protein content than do Whites, resulting in a greater fat-free body density. Additionally, there are racial differences in the distribution of subcutaneous fat and the length of the limbs relative to the trunk. Systematic error can result in the inaccurate estimation of the relative body fat of Blacks, and therefore of definitions of obesity, if these inherent differences are ignored. @nacionalismoidentitario https://ajcn.nutrition.org/article/S0002-9165(23)07178-2/fulltext
