Anonymous asked: Do you happen to know why male primates/humans have nipples?
Because females have nipples. And males would look weird with just hair there.
A more science-y explanation is that it’s a developmental holdover. Some people would claim they’re vestigial organs, but it never evolutionarily served any purpose whatsoever (so they’re wrong!). Some people would claim it to be an evolutionary spandrel, which admittedly is a much better guess (so they’re not completely wrong depending on their argument) because it’s not adaptive in any which way for males to have this (surprise! sometimes evolution gives us nonadaptive traits!). But when you look at the biological development, it makes more sense that they’re just developmental holdovers. And that’s because everyone starts off female in utero (yup, females are the default sex). Male nipples developed before sexual differentiation occurs. So which is it, developmental holdover or evolutionary spandrel? It’s always best to abide by Morgan’s Canon that the simplest explanation is the best explanation. And in that regard, developmental holdover wins.
So basically, males have nipples because females have nipples.
From how I’ve always understood it is that if males didn’t have nipples, there’s a chance that they’d pass that trait on to a female offspring and that female wouldn’t have nipples and they’d be unable to feed their children and that would basically cause the end of that genetic mutation.
But like you said, males have nipples because women have nipple, but more so that males have nipples in order to ensure that women have nipples.
Scientists predict humans will be extinct within 100 years
Eminent Australian scientist Professor Frank Fenner, who helped to wipe out smallpox, predicts humans will probably be extinct within 100 years, because of overpopulation, environmental destruction and climate change.
