matter Posted February 28, 2004 Share Posted February 28, 2004 Has anyone ever questioned why we have fingerprints, and their purpose for our species? Are they just a product of our genetic differences? Thanks for reading. Link to comment Share on other sites More sharing options...
YT2095 Posted February 28, 2004 Share Posted February 28, 2004 they`re used for grip basicly, and also to provide chanels for cooling via perspiration Link to comment Share on other sites More sharing options...
aommaster Posted February 28, 2004 Share Posted February 28, 2004 Oh yeah talking about fingerprints, don't identical twins have the same fingerprints? Link to comment Share on other sites More sharing options...

mooeypoo Posted March 5, 2004 Share Posted March 5, 2004 I might be reviving an old thread here, but I was thinking about something YT said -- they`re used for grip basicly,and also to provide chanels for cooling via perspiration The grip thing I got But perspiration... won't it have to appear on other parts of the body then, like anywhere else on the skin, or on the places that are usually more "sweaty" than others like armpits and such? How does it help in perspiration..? Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted March 6, 2004 Share Posted March 6, 2004 I dunno. It's not like they'd really help. If that was true, our armpits would have "armpitprints." Link to comment Share on other sites More sharing options...

YT2095 Posted March 6, 2004 Share Posted March 6, 2004 perhaps I made my post a little confusing, lemme explain. we perspire all over our bodies (sweat) but could you imagine having smooth (no finger prints) and still having sweat. grip on things would be terrible, espcialy things like metal or glass, so the pirints provide channels for this liquid and still allow us some grip even with wet hands Link to comment Share on other sites More sharing options...

Thorin Posted June 15, 2004 Share Posted June 15, 2004 In response to Aommaster's post "...don't identical twins have the same fingerprints?" I'm an identical twin and my brother and I have different fingerprints. I've done some research and it seems that fingerprints also depend on the embryonic environment to help develop their pattern, which causes slight variations. Now we do still have the same DNA, but a fingerprint would identify the individual. So much for advanced science, LOL. As for Brainman's later comment: "Fingerprints help with fine sensations." The main function of the fingerprint is to increase the available surface area that can be used for grip, nerve endings, "breathing," and so on; more than just "tire tred" for your fingers. The ridges exponentially increase the surface area. Link to comment Share on other sites More sharing options...

Thorin Posted June 22, 2004 Share Posted June 22, 2004 Dov, the article also says that "Identical twins have the same DNA configuration but they do not have identical friction ridge configuration." Thanks for the verification. Link to comment Share on other sites More sharing options...
