Fingerprint Whorling







Fingerprint Articles









Artie says: What about toeprints?! Because chimps do walk on their feet, we may have trouble finding fingerprints, but I suggest a fine inspection. Seems that their should be a faint rudiment, unlike in human toes where the fingerprint is completely erased.
Depends. Where opposable thumbs are present, if there are fingerprints on the fingers but none on the toes, I think it must be because the fingers are precisely used for the manipulatation of tools. I believe that the whorling of fingerprints must have evolved through handling of objects and tools and contact of each finger with the opposable thumb.





QUESTION: What's on the tail of a New World monkey that we humans have as well, and essentially for the same biological reason, though for us their cultural function gets most of the attention? -- St. J. Davis

ANSWER
: Fingerprints, a.k.a. friction ridges or dermatoglyphics (literally, finger writing), which appear on the palms of the hands and soles of the feet of many mammals, says Nina Jablonski in Skin: A Natural History.

Many have lines and prints on their palms and hands. The lines are easily explainable from the opening and closing of the hands. In the case of humans having these lines on the feet, it is evidence of once having four "hands". New World monlkeys have prehensile tails that they use for grabbing and gripping. Thus the fingerprints on the tail.

Artie says: This section is concerned with whorling as the ears seem to have whorls from the inner to outer ear. The only other swirling of skin on the body, to my knowledge, is the whorling of fingerprints. How do whorls on the fingertips come about? although there is much said about palmprints, fingerprints and sole, I found nothing about toeprints. What I am looking for is a toeprint in the sense of a fingerprint. Not just the outlined shape of the toes but prints on the toes. I will see if I can examine a newborn baby for toeprints. Another question is: do chimps have toeprints? Why is this important? Because if fingerprints are the result of friction between the thumb and fingers then toeprints would be lost as the opposable thumb straightened and human stood up. So maybe chimps have prints on their toes? I can't find any clear pictures on the web so I'll have to visit a zoo.
