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]

Missing fingerprints can have various causes: the 'hand-foot syndrome' + genetic disorders.

No fingerprints: about the ‘hand-foot syndrome’ and genetic disorders’

What if a person has no fingerprints? Likely there are 2 options: (1) the person was born without fingerprints (due to a genetic disorders), or (2) the person has ‘lost’ his/her fingerprints during a chemotherapy (in a cancer treatment) – a missing fingerprint is often featured with the ‘hand-foot syndrome’.

By the way, having no fingerprints used to be no big deal. But the situation is changing rapidly due to the evolving applications of biometric fingerprint readers. In many countries fingerprints are required to: pass the nation’s border, and to get a drivers licence and/or passport!

TWO ANECDOTES FROM THE PAST FEW YEARS:

“Last month (april, 2009) a Singapore-based medical oncologist reported a letter that was presented online in the journal ‘Annals of Oncology’, titled: Travel warning with capecitabine. The trade name fot the cancer medicine capecitabine is ‘Xeloda’ – a medicine that is often prescribed in patients with breast cancer and colorectal cancer. But the oncologist’s patient had been using the drug to treat his nasopharyngeal cancer.

Two years ago, Spanish cancer doctors reported a likewise story about the 39-year-old flight attendant Cheryl Maynard detained for several hours at a U.S. airport until her doctor faxed an explanation that the capecitabine she’d been taking for breast cancer had erased her fingerprints.”

The history of fingerprinting: a perspective from Iran

About the first fingerprint in the old Persia (= Iran); the uniqueness of a fingerprint; and why the Iranian gouvernement plays ‘tit for tar’ on fingerprints.

“Each one of you has something no one else has, or has ever had: your fingerprints, your brain, your heart. Be an individual. Be unique. Stand out. Make noise. Make someone notice. That is the power of individuals”!

Quote from: John Bon Jovi.

Fingerprint-based identification is the oldest biometric techniques which has been successfully used in numerous applications: the full article presents an Iranian perspective on the history of fingerprinting.

The article includes a detailed description about the methods of identification used in early civilizations, the early history of fingerprinting, and the first Iranian record on fingerprinting.

The function of fingerprints: ‘finger grip’ + ‘touch filter’:

Many palmists & hand analysts including the fingerprints in a hand reading. But what is the basic function of our fingerprints really?

Researchers from Paris (France) have recently presented new evidence that your fingerprints not only provide ‘finger-grip’, but the ridges also function as a filter for the human touch!

The word ‘fingerprints’ refers to the impressions made by the skin ridges on the fingers & thumbs – by the way: palms can leave the same impressions: ‘palmprints‘.

The major function of these skin ridges is to provide ‘friction’, or ‘traction’, when we grasp objects in daily life. And as a consequence because of the presence of skin ridges on our fingers & palms, objects held in our hands do not slip through our fingers.

For many years scientists believed that the fingerprints (skin ridges) have a second function: the enhancement of our sense of touch. But untill recentely there was hardly any hard evidence for this assumption. But times have changed since january 2009: French physicists at the ‘École Normale Supérieure‘ in Paris have presented new research. They found that the skin ridges (fingerprints) also amplify / filter vibrations triggered when our fingertips brush across an uneven surface. These processes help transmiting the signals of ‘touch’ to deeply embedded nerves involved in fine texture perception.

Some facts reported by the French fingerprint research:

• The researchers report that certain vibrations from the patterned fingertip are 100 times stronger than those from the smooth fingertip.

• The distinctiveness of fingerprint patterns from one person to the next does NOT(!) seem to have an effect on filtering capabilities – so regarding the sensitivity for ‘finger-touch’ it hardly makes any difference what type of fingerprints you have!

• The research was done with an ‘artificial fingertip’ – the first ever presented in the world!

In the near future a careless touch might be enough for police or insurance companies to determine your identity, your criminal history and certain medical conditions. This article about fingerprint technology explains the details!

Drugs aren’t the only chemicals the new tests could detect. Cancer, diabetes, heart disease and other medical conditions produce specific chemicals also secreted in sweat and oil.

By tweaking the antibodies on the particles, forensic scientists could test for a variety of medical conditions. This could help police track down a suspect by, say, watching the local kidney dialysis clinic if the suspect has kidney failure.The new fingerprint analysis doesn’t only monitor the body’s internal environment – it also reveals external information. If a person fires a gun or has handled explosive material, trace amounts of those chemicals are left on the hand, which can then be detected if the person leaves a fingerprint.

Identical fingerprints?

The fingerprints of identical twins have been the subject of many fingerprint studies. The short version of this answer is descibed at Examiner.com (see below).

FULL ARTICLE:
Do identical twins have identical fingerprints?

Straighdope.com says:

“Identical twins have fingerprints that can be readily distinguished on close examination. However, the prints do have striking similarities. In fact, before the arrival of modern genetic testing, similarity of fingerprints was often used to determine whether twins were identical- or fraternal twins.”

The most popular set of names for twins in 2007 was: ‘Jacob and Joshua’.
