Why are male animals often more attractive, while humans tend to find females more attractive?

This phenomenon has reasonable explanations in biology and evolutionary science, mainly related to **'mating strategies' and 'raising offspring'**: 1. Animal Kingdom: Female Choice, Males Compete with 'Beauty' Parental Investment Asymmetry: Female animals have fewer eggs and bear the costs of pregnancy and lactation, giving them absolute 'choice'. Showcasing Superior Genes: To compete for mating rights, males must evolve bright feathers or magnificent manes (like peacocks, lions). These appearances serve as visual signals to females, proving their 'health and good genes'. 2. Human Kingdom: Mutual Selection, Female Appearance Linked to 'Health & Fertility' Bidirectional Sexual Selection: Raising children is very challenging for humans, requiring joint parental effort, thus males also strictly select their partners. Evolutionary Visual Signals: Smooth skin, symmetrical faces, and waist-to-hip ratios in females are evolutionarily linked to 'youth, health, and good fertility'. To attract males to stay long-term and provide resources, females have evolved sustained visual attractiveness. Cultural and Cosmetic Enhancement: Modern society also places more cultural emphasis on clothing and makeup for women, reinforcing the impression that 'females are more attractive'. In simple terms: Animals involve 'males showing off to please females'; humans involve 'mutual selection, with female traits evolving into signals of health'.
