For this context? Yes? Clearly the article answers that already. I even included in my first reply but you'll have a third chance to read it:

> ...which are very important for scarring...

And your attempt to move the goal post fails miserably as well. Or do you think humans evolved to perfection by thinking this:

I don't think you are debating in good faith. Good luck.
