Question

why females are attractive than male in every multicellular organisms
​

Answer 1

Answer:

In most multicellular species, these strategies became inextricably mixed, and sexual behavior increasingly more – and in most species even exclusively – ‘served’ the interests of reproduction: sexual behavior became more or less synonymous with reproductive behavior. In most species, the ‘mix’ of sexual and reproductive strategies evolved into typical gender-related patterns of behavior, that is, in typical ‘sex-roles’. Often, males are bigger and more ‘beautiful’ ( = more intensely ornamented) than females; males compete with each other for access to females; males court females, while females choose males (‘female choice’).
