Does pubic hair have a specific function?

Does it have any beneficial effect or is it just there to run wild and free?

I don't yet see anyone mentioning that pubic hair can act as a visual signal of sexual maturity. Of course, we don't use it as such today, when we wear clothing and prosecute people who go after young people who might even yet have had pubes for several years (and rightly so). Nevertheless, it does serve as an external signal positively indicating the hormonal prerequisites for reproduction.
