Why do certain sounds make your skin crawl?
Nails on a chalk board, squealing brakes, or a crying baby are all sounds that can make one's skin crawl. Why does this happen? The answer involves how the brain processes sounds. When we detect a sound, sound waves travel to our ears and the sound energy is converted to nerve impulses. These impulses travel to the auditory cortex of the brain's temporal lobes for processing. Another brain structure, the amygdala, heightens our perception of the sound and associates it with a particular emotion, such as fear or unpleasantness. These emotions can illicit a physical response to certain sounds, such as goose bumps or a sensation that something is crawling over your skin.
Why do identical twins have different fingerprints?
Although identical twins share the same DNA, they don’t look identical cell-for-cell, because not every aspect of your physical appearance is rigidly determined by your genes. Fingerprints are formed semi-randomly as the fetus develops in the womb and are affected by such things as chance fluctuations of hormone levels. Similarly, the pattern of freckles and moles on the skin is caused by random mutations and will vary between identical twins.
