早熟和晚熟这两个词你没听过吗，还有现在衣服的起源学界都还没有得出结论，到了你这里就变成常识了？现在有的也仅仅是几个假说而已，还是你不只是个金融从业者，还是个人类学大佬？
Origin and history
First recorded useAccording to archaeologists and anthropologists, the earliest clothing likely consisted of fur, leather, leaves, or grass that were draped, wrapped, or tied around the body. Knowledge of such clothing remains inferential, since clothing materials deteriorate quickly compared to stone, bone, shell and metal artifacts. Archeologists have identified very early sewing needles of bone and ivory from about 30,000 BC, found near Kostenki, Russia in 1988.[13]Dyed flax fibers that could have been used in clothing have been found in a prehistoric cave in the Republic of Georgia that date back to 36,000 BP.[14][15] Scientists are still debating when people started wearing clothes. Ralf Kittler, Manfred Kayser and Mark Stoneking, anthropologists at the Max Planck Institute for Evolutionary Anthropology, have conducted a genetic analysis of human body lice that suggests clothing originated quite recently, around 170,000 years ago. Body lice is an indicator of clothes-wearing, since most humans have sparse body hair, and lice thus require human clothing to survive. Their research suggests the invention of clothing may have coincided with the northward migration of modern Homo sapiensaway from the warm climate of Africa, thought to have begun between 50,000 and 100,000 years ago. However, a second group of researchers using similar genetic methods estimate that clothing originated around 540,000 years ago [16] For now, the date of the origin of clothing remains unresolved.

而且这位还死要套用现实的情况去分析，连成长的环境都不一样，能拿来比较吗，没学过控制变量法吗，真要说明的话，可以等自己有了孩子，完全让他与这些性相关的东西隔离，看看结果是不是和国家队里面的情况一样啊
