straight, long and narrow nose with very high nasal bridge is ideal. in nature such type of a nose (the so called greek profile) is practically non-existent (although white people are the closest to this). and this is the most far appearance from primitive times, from the resemblance to an ape. perhaps the ancient greeks didn't know darwin's theory but subconsciously on a visual level they sensed something (and even now we can see measurable "robust" and "refined" facial features).
