Here is a question I don't know the answer to.

What is the point of scar tissue? It is less strong thatn normal
tissue, it doesn't breath air or water and so doesn't fill the purpose
of normal skin. So why have it? Why doesn't the body heal properly?

I've heard that unlike adults unborn babies don't scar when cut, is
this true? Does it last until some days/weeks after being born?

If so, then what would be the point of an adult scarring if the body
has the ability to heal properly?
