Why do we have moles on our skin?

What are they made up of and what is their purpose?

Why do we have moles on our skin?
there are many different kinds, some are caused by the sun, sunlight increases the melanin in the skin cell (which makes us tan) and some cells produce too much at the same point and the melanin clusters together to create a mole, either fading with time or become permanent. Hormones can cause it too (some pregnant women can suddenly develop brown spots, which do fade). It can also be hereditory, if your mum/dad have lots good chances are that your skin will be similar.

2) "The high concentration of the body’s pigmenting agent, melanin, is responsible for their dark color. Moles are a member of the family of skin lesions known as naevi."





So yea basically from what I understand they are just skin defects.. I have also heard that hey can appear form prolonged periods in the Sun, but I dont know if thats credible.
