Why do some people have nose bones and others don't?

Question

We probably all have bones in our noses but I was wondering why some noses protrude and others cave in and all of that

Answer 1

Unless a person has a congenital malformation or has suffered an accident, we all have nasal bones. These are rather short paired bones, situated at the base of the nose forming the hard 'bridge'. The rest of the nose is not formed by bone but by other connective tissues and cartilage (especially supporting the more flexible nasal septum).
The shape of the human nose varies according to ethnic and individual characteristics; and of course, it also changes also during a person's life.

Some anthropological studies have proposed adaptive explanations for the different nose shapes, while other studies have found little functional correlations (see http://www3.interscience.wiley.com/cgi-bin/abstract/109716681/ABSTRACT?CRETRY=1&SRETRY=0 )

In any case, all our noses are quite prominent compared to our closest relatives! And that's probably a consequence of allometric changes

Answer 2

Evolution, the influence of natural and social environments, and genetics.

Answer 3

Its not bones, its cartilage.
Its genetics.
