Fingerprints reveal Clues about Sexe, Race, Diet, Lifestyle & Disease!

Papillary ridges in a fingerprint.

The papillary ridges in every fingerprint are unique to each individual, and these characteristics do not change over time (after fixation during the 2nd and 3th prenatal month). Therefore fingerprints became recognized as a usefull tool for identification. However, the certain details in a fingerprint + the distribution of the pattern types among the 10 fingers can reveal much more!

In general, one could say that beyond identity fingerprints can reveal clues that relate to: sexe, race,  diet, lifestyle, and disease. Below follows an introduction to how fingerprints are related to these themes.


FINGERPRINTS & SEXE:

Biometric studies have shown that fingerprint type distributions & palmar dermatoglyphics vary significantly among both sexes: females have more arches, and males have more whorls. However, another stricking sexe-difference is that females usually have more ridges per cm2.


FINGERPRINTS & RACE:

Anthropologic studies have revealed that fingerprint type distributions vary significantly among the populations around the world. More details have been reported in the posts about the Fingerprint World Map & the World Populations.


 FINGERPRINTS & DIET:

A few years ago reports have been made that using commercial gelatine based tape (which was already used by police) and high-tech chemical analysis under spectroscopic microscope – provides a detailed picture of the chemical- & metabolic make-up found on a fingerprint. The study revealed that specific amino acids indicated whether the “suspect” was a vegetarian or meat-eater, and different fatty acid profiles suggested provided clues to their racial origins. 


FINGERPRINTS & LIFESTYLE:

The same microscope method (based on the study of chemicals & metabolics featured with a fingerprint) can also unveal e.g. the use of substances, including: cigarettes, drugs & grooming products. And even age can be determined roughly with this method!


FINGERPRINTS & DISEASE:

Scientists have stated that the scientific study of dermatoglyphics in an individual (via: the palmar dermatoglyphics & the fingerprints) can tell doctors about the risk for certain diseases. Multi-Perspective Palm Reading describes the link between fingerprints & diseases by detail!

World Population Study shows: Fingerprint in Pointer Finger is most unique!

with one comment

Every person has unique fingerprint. In the forensic sciences the process of comparing two fingerprints – known as ‘dactyloscopy‘ – is focussed on identifying tiny characteristics in the friction ridge skin. However, fingerprint pattern types are not unique at all: they e.g. fingerprint pattern types highly depend on sexe & race. An international study points out that the fingerprint type in the pointer finger is most unique!

In order to study the interactive effects of sexe & race in fingerprints (dermatoglyphics), a study has been conducted on fingerprint samples in 5 world populations (2.785 people) – including: Americans (A), British (B), Chinese (C), Iranians (I), and Nigerians (N). 

Only the so-called Vucetich fingerprint types were considered in this study, which is founded on the number of triradii + their location:

– whorls are characterised by the presence of 2 triradii;
– ulnar loops are characterised by the presence of 1 triradius positioned at the thumb-side;
– radial loops are characterised by the presence of 1 triradius positioned at the pinky-side;
– arches are characterised by the absense of a triradius.

The results of the study are shown in the picture below:

FINGERPRINTS & SEXE:

International studies in the past have shown that fingerprint types in females almost universally differ from males in having more arches. And usually females also differ in bearing fewer whorls, and typically they also tend to have slightly less radial loops.

The new study shows that in all 5 populations arches are much more common in females: +44.9% (compared to males); and whorls are indeed less common in females: – 10.5% (compared to males). And as expected the sexe-effects in radial loops (-0.6%) and ulnar loops is much smaller (+2.3%).

Interestingly, the most typical sexe-effect for arches is by far less prominent in the index finger: +11.5% (compared to the other fingers: thumb: +57.6%, middle finger: +69.4%, ring finger: +58.4%, pinky finger: +123.1%). This indicates that the fingerprint type in the index finger is least ruled by sexe.


FINGERPRINTS & RACE:

The Fingerprints World Map has shown that studies in the past have shown that the occurence of fingerprint types varies significantly in the populations around the world: e.g. Asians are known for a higher occurence of whorls, and Africans for a higher occurence of arches.

The new study confirms these earlier findings:

– Whorls are by far most common in Chinese males (48.2%) and females (45.4%);
– Arches are by far most common in Nigerian females (13.7%) and males (9.1%).

Interestingly again, the details show that the most typical racial-effects are least prominent in the index finger – in the picture this is e.g. also indicated by the relatively small variance for the ulnar loops among the races!


POINTER FINGER  HAS THE HIGHEST VARIABILITY:

Summarizing, the study has shown that sexe & race have relatively small effects on the fingerprint type of the pointer finger.

And this might actually makes sense, because the pointer finger [index finger] is known for displaying the highest level of variability – e.g. arches & radial loops are known for manifesting by far most often on the index finger (and the same is true for less common fingerprint types such as: the tented arches & accidentals).
