Blog #8 fingerprints.

Fingerprints. One of the easiest ways to identify someone.  Chances that two people have the same fingerprints are extremely slim, but not impossible. In fact, the odds are 1 in 64 billion. That is one of the reasons why we require multiple fingerprints on more than one hand. Fingerprint shape is completely unaffected by your DNA, and starts to form while you are still in the womb. While it is hard to duplicate a fingerprint, it is easy to identify which one of three standard pattern you have. One of the simpler fingerprint pattern is the Whorl which is multiple circles. The Loop, which is more of a wave like pattern in the center of your finger. The Loop is more of a personal shape, since it has more complicated pattern and ridges. The Arch resembles a hill or bump illusion. I have the circle pattern.
Scientists believe we have the ridges on our fingertips may also enhance our sense of touch. Also they are used to be able to grasp things. That way objects don't slip threw our fingers.  Wonder what animal has similar fingerprint patterns like a human being? The answer is: a koala. The only differences between our fingerprints and koalas are, koalas have two thumbs on each hand, as well as claws instead of fingernails. Well, hope you learned something new today, until next time.

  1. WOW! I have to say, your blog post was very interesting. I definitely learned something new. I always wondered why we have to take finger prints with all your fingers instead of just one finger. Great post.
