DERMATOGLYPHICS: An introduction to the dermatoglyphs of the human hand.

Dermatoglyphics – News, reports & research!

The word ‘dermatoglyphics‘ was introduced in 1926 by Harold Cummins – the word refers directly to the study of the patterns & characteristics of the skin ridges in the human hand (and foot). What are the basic characteristics of the dermatoglyphics in the human hand?

FINGERPRINT DERMATOGLYPHICS:

In most populations around the world is the ‘ulnar loop’ the most observed fingerprint pattern (see: the fingerprint of the pinky finger in the picture above). Loops are most frequently found on the little finger (and middle finger); loops are least frequently found on the pointer finger.
In some Asian populations the ‘whorl’ (see: the fingerprint of the ring finger in the picture above) is more common than the ‘ulnar loop’. Whorls are more often seen on the thumb and ring finger.
In population research usually the pointer finger demonstrates more variation than the the other fingers. For example the most common ‘ulnar loop’ is least often seen on the pointer finger, which often exhibits an other pattern such as: the ‘arch’, ‘tented arch’, ‘whorl’ or ‘radial loop’ (see: the pointer finger in the picture above).

PALMAR DERMATOGLYPHICS:

The variations in the dermatoglyphics of the handpalm are much more complex than the variations in the fingerprints. An important element concerns the presence of the ‘palmar triradii’ (see: a, b, c, d, and t in the picture above): normally each finger is featured with a palmar triradius – triradius t belongs to the thumb (the thumb mouse – a.k.a. as the ‘thenar’, or in palmistry: ‘mount of Venus’ could be recognized as the third phalange of the thumb).
However, the number of palmar triradii varies with the presence of palmar ‘loops’ (or: palmar ‘whorls’). Usually the link between the number of fingers (D = digits), palmar triradii (T) and palmar loops (L) can be described with the following formula, which is known as the Penrose topological formula (Lionel Penrose, 1965):

T = L + D – 1

[NOTICE: The picture below includes a small mistake: the hand palm usually has 1 single palmar ‘loop’ featured with 5 palmar triradii – this implicate that ‘c-line’ (which starts in the triradius below the ring finger) should have ended between the pinky finger and the end of the heart line – and not between the ring finger and middle finger as indicated by the picture]

Usain Bolt, fastest man on earth, sprint talent is in his fingers!

Usain Bolt has the marker for sprint talent: a long ring finger!

The 2008 olympics in Beijing pointed out that Jamaican sprinter Usain Bolt is the fastest man on sprint ever! And last sunday he set another new world record at the Athletics World Championships 2009 Berlin. How come that Jamaican sprinters run so fast?

Earlier this year British researchers studied the hands of 241 boys aged 10 to 17 who took part in a sports talent-spotting competition in Qatar. And the results pointer out that a low 2D:4D finger ratio is linked with a fast sprint!

Professor John T. Manning (a.k.a. ‘the finger professor’) about the research:

“We found finger ratios of the right and left hand were positively linked with sprinting times in boys. The advantage they had was soon apparent after the start of the sprint and remained steady thereafter.”

Previous studies have confirmed the link between finger length and sprint talent: long-distance runners have the same hand characteristics – a ‘low 2D:4D finger ratio. But to understand the implications in this perspective one should be aware that the long ring fingers has also been linked with other ‘testosterone’ related matters such as: a lower risk of heart disease and good results in exam success in mathematics, to male aggression and higher earnings at the London Stock Exchange.

So the predictive value of a long ring finger is actually pretty, and certainly not reliable in individual subjects.

Nevertheless, John T. Manning has described in his first book – ‘Digit Ratio’ – that the hands of Jamaicans are usually featured with a relatively long ring finger – which is confirmed by various hand photos of the most successful sprinters from Jamaica (see the photo below).

Presidential Palmistry Readings: how to recognize the hand of a US president?

A few weeks ago TIME.com presented a beautiful photo essay focussed on the right hand of the last 9 US presidents – including the hands of: Barack Obama, George W. Bush, Bill Clinton, George H.W. Bush, Ronald Reagan, Jimmy Carter, Richard Nixon and Lyndon Johnson.

An american palm reading expert Robin Gile to makes some comments about the hands of all 9 presidents. His assessment was made ‘blind’ without knowing which hand belonged to which president!

Now the article is also available in a more extended form – including: the hands of John F. Kennedy, 6 hand photos of each president + an analysis of the most common hand characteristics in the presidential hands.

The new article is titled:

10 presidential US palm readings: from Barack Obama to John F. Kennedy!

WHAT DO THE PRESIDENTIAL HANDS REVEAL?

The article demonstrates that all presidents appear to have a long ring finger – which is known as a typic male-like hand characteristic. Interestingly, next to the long ‘sun finger’ (a synonym for the ring finger), a high percentage of the the presidential hands is also featured with a strong, long sun line! And most of the presidents also appear to have low ‘2D:4D finger ratio’ – which is indicated by a ‘digit ratio’ (index finger vs. ring finger ratio) lower than 0.96, another typical male-like characteristic!

Beyond the results related to the ‘sun finger’ the presidential hand analysis also indicates that quite a few of these ‘presidential men’ appear to have a rather remarkable characteristic in their ‘head line’ (in the world of palmistry a.k.a. the ‘line of head’ or ‘headline’):

The Sydney Line

The Sydney line is known as a rather unusual long palmar ‘head line’ (which is usually found in less than 5% of normal populations).

The presidential photos indicate that the following 4 presidents have this unusual hand characteristic: George H.W. Bush (both hands), Jimmy Carter (both hands), Gerald Ford (both hands), and Richard Nixon (right hand only).

The double head line

The ‘double head line’ is another unusual palmar characteristic (which is also found in less than 5% of normal populations).

The presidential photos indicate that both Bill Clinton (left hand) & John F. Kennedy (right hand) have the ‘double head line’.

The hands of Michael Jackson – what does his palmistry reading reveal?

The wax hand cast above is Michael Jackson’s right hand – which is presented at London’s “Madame Tussauds“. What does his hand reveal about his life and death?

First of all, it is also interesting to notice that Michael Jackson’s right hand cast at “Madame Tussauds” reveals much more details about his hand lines than any public photo of his hands! Hand experts have noticed that Michael Jackson’s hands are rather remarkable and present quite a few tell-tale stories!

For example:

1 – In both hands Michael Jackson has a ‘double headline’: which can be recognized as a sign of a ‘double nature’ and an ‘eccentric personality’.

2 – Especially in his right hand is the thumb-angle a bit narrow (though in his left hand the thumb angle is wider): which can be recognized as a sign of being cautious (especially later in life).

3 – The combination of his relative long ring finger + strong thumb mouse (a.k.a. the mount of Venus): can be recognized as a sign of charismatic & spontaneous personality.

FULL REPORT: THE HANDS OF MICHAEL JACKSON

The famous palmist Cheiro wrote about the ‘double line of head’:

“A double line of head is very rarely found, but when found it is a sure sign of brain power and mentality. Such people have a perfectly double nature — one side sensitive and gentle, the other confident, cold, and cruel. They have enormous versatility, great command of language, a peculiar power of playing and toying with human nature, and generally great will and determination.”

Five things about hands, fingers & digit ratio.

Five things about: hands, fingers & digit ratio.

What your five fingers reveal about: human evolution, sports, social behavior, disease & your sex-life:

In 2008 Professor John Manning at the University of Swansea presented the book “The Finger Book”. The book explains how the ratio of the index finger and ring finger is related to various aspects life. Let’s take a look at his major findings + developments in the ‘finger research’ – including an update from 2009!

WHAT FINGERS REVEAL ABOUT HUMAN EVOLUTION:

The human thumb is known as a ‘marker’ for the evolution of human kind; however our relative long index finger – compared to the ring finger – is a likewise example. In the chimpanzee and gorilla, this hand feature is different: they always have longer ring fingers and a short index finger.

THE LONG RING FINGER & SPORTS:

Exceptional performances in sports are being linked to the amount of male hormones that people absorb before birth while they stay in the womb. The ‘digit ratio’ has frequently been used to predict performances in various sports leagues. In this perspective another interesting research was presented in 2009:

Research from the university of Cambridge points out that financial traders with the lowest ‘2D:4D digit ratios’ have earned 11 times more money than stock traders with a relatively high finger ratio – see the picture below.

Earnings of stock traders at the London Stock Exchange appear to be related to their finger length.

THE LONG INDEX FINGER & SOCIAL BEHAVIOR

Interestingly, especially among children a short index finger may indicate a lack of empathic ability. In general: the longer the index finger, the more people are inclined to learn social behavior and to develop strong empathy for the feelings of others and yourself.

CROSS-CONTAMINATION

There is growing statistical evidence that our finger ratios are a reliable predictor of our receptiveness to diseases. However, in real life the findings have not yet shown to have a significant impact.

YOUR FINGERS & YOUR SEX-LIFE

Men with long ring fingers, consider themselves as attractive. Studies show that women in the general rule agree and confirm the judgements of these men. Surprisingly, a likewise result has been found in women.

Low index finger vs. ring finger ratio relates to financial success

Researchers at the University of Cambridge found that stock traders with a lower digit ratio of 0.93, on average, earned 10 times more than those with an average ratio of 0.988.

Traders with a lower digit ratio made an average of 679,680 pounds (or about $1 million U.S.), compared with 61,320 pounds ($90,956 U.S.) by those with a higher ratio, the report said.

The research, published today in the journal Proceedings of the National Academy of Sciences (PNAS), found that individuals who were exposed to high levels of prenatal testosterone tended to be more profitable traders.

The British researchers provide the following explanation for their finger length research results:

Testosterone, a steroid hormone, surges between the 9th and 18th week of gestation, exerting powerful organizing effects on the developing body and brain. According to both animal and human studies, these effects may include increased confidence, risk-preferences and search persistence, as well as heightened vigilance and quickened reaction times.

The amount of testosterone one was exposed to in the womb can be measured because it leaves traces throughout the adult body. Measures of prenatal androgens are increasingly used by paediatricians to gauge whether a newborn has been exposed to abnormal levels of steroid. The most common measure for behavioural studies is the ratio of the index to ring finger (2D:4D) on the right hand, a relatively longer ring finger – lower 2D:4D – indicating higher prenatal testosterone levels. Males typically have ratios below 1, women above 1.

As digit ratios have been found to predict performance in competitive sports such as tennis, football, and skiing, the scientists hypothesised that 2D:4D may also influence the risk preferences and physical speed required for what is variously called noise or high-frequency. Traders engaged in high frequency trading look for fleeting price anomalies and hold their trades for minutes, sometimes mere seconds.

What relates basketball to fat? Your hands and fingers!

What relates basketball to fat? Your hands & fingers!

Big hands, basketball & fat:

You may have wondered sometime: why do basketball players have big hands and long fingers? The question is answered by researchers at the University of Alberta and the University of California-Riverside. Their research results indicate that individuals with a long index finger compared to the ring finger (a low ‘finger ratio’) appear to more inclined to voluntarily participate in intense physical exertion.

The results indicate that if you absolutely detest exercising, it may not be due to laziness or lack of willpower… it might be related to your hormones & the length of your fingers! Although the researchers believe their findings are applicable to humans, the study actually involved 1,000 white mice. And you probably weren’t even aware that mice had fingers.

The men in white aren’t perfect specimens, mind you — 44 percent are overweight and 6 percent are obese — but that’s considerably leaner than the general public, 65 percent of whom are overweight, and fully 32 percent obese. Yours truly has no idea why the Harvard Physicians’ study did not include female M.D.s, but simple cowardice comes to mind.
