Distinct from other apes,
human males develop facial hair at puberty that creates a beard and mustache. Then many men shave it off. If you’ve ever wanted to know why, here are some recent hypotheses.
According to the BBC online, “beards probably evolved at least partly to help men boost their standing among other men.” because women are not more interested in men with beards. “To reproduce, it’s often not enough to simply be attractive. You also have to compete with the same sex for mating opportunities.”
“A man’s ability to grow a fulsome beard isn’t actually neatly linkedto his testosterone levels. “
“Men on average also think their body should be more muscular than women report that they want, while women on average believe they need to be thinner and wear more make-up than men report that they want.”
“Make-up use, average body composition, and even the very ability to grow facial hair all differ enormously across the world – meaning we could get different results elsewhere.”
