      We all inherit different things from our ancestors, and our environment encourages us to express different parts of those inherited things. Also, blemishes and scars make even the most similar looking people different after a short time.

      My ‘identical’ twin boys were noticeably different even before they were born, mostly due to their different experiences as they grew in the womb.

      DNA tells your cells what they should do and how they should work Everyone’s is different (because it’s inherited from your parents)
