The big male nose: Why men's noses are bigger than women's

Why are men's noses bigger than women's? The answer, according to a new study lies in our physiology. Men's noses are about 10 percent larger than female noses, on average, because males have more lean muscle mass, which requires more oxygen for muscle tissue growth and maintenance. It also explains why we have smaller noses than our ancestors.
