In fact, everything that is considered romantic has these two characteristics: 1, which is either extremely time-consuming and laborious or extremely expensive to achieve; 2. No practical value.
Why is such a thing considered romantic and favored by women? This will start with the different strategies of gene transfer between male mammals and female mammals. Because men's sperm is almost unlimited and there is no burden of pregnancy, the cost of gene transfer for men is very small, so the strategy tends to focus on quantity rather than quality. But women are different. If females don't raise a limited number of offspring, it will be difficult for them to pass on their genes.
For this reason, women are more inclined to choose men who can and are willing to provide living resources. In other words, women with this tendency are more likely to inherit their own genes. In the long process of natural selection, this tendency has become a dominant trait that can be inherited.
So how to judge whether men can and are willing to provide living resources? Say "yes" first. In the case that it is difficult to directly judge how many biological resources there are or whether everyone's biological resources are similar, it is helpful to judge who owns things that are useless or even harmful to survival. Because when everyone is living, the more time and energy you spend on scarce and useless things, the easier it is for you to survive. Through this, women can find men who are more capable of providing living resources. For example, Gao Fushuai's "height" belongs to things that are useless or even harmful to survival. "High" means that it is difficult to hide when hunting, and it also means consuming more energy. Then when everyone is alive, women will think that tall men have stronger ability to obtain living resources and have more living resources than short men. From this perspective, men's preference for jewelry and their preference for tall people have something in common in evolution.
Besides, "willingly", men do expensive and useless things to women, but they also have the function of expressing loyalty. Show that you are willing to continue to provide survival resources after mating to ensure the survival of women and future generations.
