Research into the nasal structure has shown that its size may be linked to specific physiological advantages that aid in the male's ability to thrive and maintain his dominant position. A larger nose is often an indicator of good health and robust development, suggesting that the male has successfully acquired and defended high-quality resources necessary for such growth. It is, therefore, a reliable honest signal of the male's underlying genetic quality and his capability to outcompete others, offering a measurable index of his biological fitness to those observing his behavior.
