Saying we all begin as female as has been said in the comments, even physically, is so over-simplified it isn't correct at all. The default COURSE is female, yes. Without the Y chromosome male parts won't form and female parts will instead. However, sex differentiation doesn't begin until 8 weeks for both males and females. At that point, the neutral tissue becomes male organs if the embryo is XY and female organs if the embryo is XX. Until then they have neutral tissue that is neither male nor female. That neutral tissue can develop into both, whichever is needed. At no point does a male embryo ever have female organs. They never have ovaries or labia. In fact all embryos have a few structures that only males need. Wolffian ducts become testicular tissue in males, and in females the ducts just disintegrate. The FOXL2 gene actually stops females from growing testicles instead of ovaries from their neutral gonadal tissue as well. Without that gene, women would have balls even though they have no Y chromosome and no SRY gene.

Not only do men have nipples, they also have fully functional mammary glands. All it takes is the correct hormones to get a man to lactate. Though spontaneous male lactation is a sign of a serious medical condition, so if you're a dude producing milk, go see your doctor right away.

I would debate this, the Aka tribe consists of males who breast feed their children because their liver lacks the ability to filter out the prolactin in their system, one thing that happens during starvation mode. It's not something that evolution 'forgot' to erase, it's a last ditch effort to safe offspring when food is scarce.

I have asked .. why do humans have legs. We so often sit and drive when we could walk. We use snow throwers for 5 minutes of shoveling when it takes us 20 due of getting engine started..warmed..etc and we promote the beauty of legs yet we keep them covered up almost all the time(esp. in Ca ...ayy?) So why do we still have legs.

How about because, even men are capable of producing milk to feed our young. It's ULTRA rare and can be induced artificially, but the bottom line is that in terms of nipples, they're still potentially functional.

I find this video very underwhelming. For the topic they presented, they left out a lot of pertinent information. For one, males can actually train themselves to lactate. They also left out fetal information that would've been better to add than leave out.

the simple answer, when you're in ya mama nobody knows if you're a boy or a girl, neither do you. So your body starts making some nips so that if you are a girl you've got some melons. If you're a guy your body doesn't care and you got some grapes.

Gregory de Lascelles (3 years ago)
Unless I missed something, the video...strangely, does not directly answer the question. Men have nipples because all human embryos start off as essentially, female. 'Y' chromosomes don't kick in until some four weeks of development when those foetuses destined to be males, began to develop male characteristics.
KohuGaly (3 years ago)
@Gregory Lascelles their development starts before male genes stop the progress. Just think about it. If human was a hermaphrodite, would it be able to breastfeed?
Gregory de Lascelles (3 years ago)
@KohuGaly but in the human species, only females are breastfed from.  Male nipples do not have that purpose and are simply a result of our "female" embryonic beginnings. 
KohuGaly (3 years ago)
+Gregory Lascelles actually I consider nipples a sexually-neutral trait. As you mentioned, their development starts far before sexual specialization even occurs. In some species of mammals both sexes breastfeed and in some only males do.

Fish to men evolutionism is ANTI-science and holds back scientific progress and this is just one more way it does. Since they demand certain things are 'vestigial' organs and no longer have a use, science would no longer even bother finding a use from them and scientific progress is held back. For example the spleen used to be called a vestigial organ but eventually it was found out they have a use after all. http://news.nationalgeographic.com/news/2009/07/090730-spleen-vestigial-organs_2.html There's no such thing as 'evidence' for a belief the human race has never seen - that's just anti-science circular reasoning. Evolutionist "That's a vestigial organ, and here are the reasons I believe it is." "How do you know it is?" Evolutionist "Because evolutionism is true" "How do you know it is?" Evolutinist "Because that's a vestigial organ, and here are the reasons I believe it is." Making up beliefs ABOUT fossils that never happens and then claim fossils are "evidence" of it is anti-science circular reasoning, not science. Evolutionist "That's a transitional fossil - and here are reasons I believe it is" "How do you know it is?" Evolutionist "Because evolutionism is true" "How do you know evolutionism is true when it never happens?" Evolutionist "Because that's a transitional fossil - and here are reasons I believe it is" (repeat) It would be similar to someone else making up a brand new belief like "populations of trees morphed over generations eventually into human beings" and claiming fossilized tree branches and DNA similarity between tree branches and humans are "evidence" of it, and it would be just as much of an anti-science farce. Ask evolutionists to show an example of populations of fish morphing over generations ('evolving' they call it) eventually into animals we'd clearly no longer consider fish. This is what they claim happens, yet pick any animal: the human race has never observed any such thing, *hence it's observable scientific fact it does not happen until anyone ever shows it to do so*. Here's what *is* science: It's observable, scientific fact that no matter how many generations go by over the entire existence of the human race, populations of: fish remain fish, reptiles remain reptiles, birds remain birds, viruses remain viruses and so on. In spite of this, evolutionists: _(a) _*_Ignore_*_ that scientific fact_ _(b) Make up a belief _*_contrary_*_ to that scientific fact_ _(c) Where that belief _*_never happens, can only be believed in_*_ and hence can't be called science anyway but demand it be called science and contradict what IS observable scientific fact._ Evolutionism is nothing but a complete distortion of science and observable, repeatable scientific fact. Evolutionists are ignoring what is observable, scientific fact, make up beliefs that are contrary to this observable, scientific fact, where these beliefs also never happen.

@ForumLight Do you like The Wizard of Oz? Because you are strawmanning the fuck out of this. Look up the strawman fallacy, and stop making up "evolutionist" arguments. Literally nothing could convince you Christfags. In fact, the way you described science is actually true. Since you think that evolution goes against science and that means it isn't true, then what about God? By your own given definition, the Bible and God are not scientific, and by your logic, they are not real.

Multiculturalism is being promoted in every White country on the earth, and ONLY in White countries. The purpose of multiculturalism is to turn every White country into a non-White country. Under international law, that constitutes genocide. Any White person who objects to this is called a racist. But White people are now beginning to realize two things: That multiculturalism is a codeword for White genocide. That anti-racist is a codeword for anti-White.

Zerk Pacifist (3 years ago)
Not all male mammals have nipples. Well known examples include male mice, which have breast tissue but no nipples, and male horses, which have neither. In both cases, the rudimentary structures develop during embryogenesis but then degenerate. Oh, and human men can lactate and can get breast cancer (100 times less common than in women but poorly understood). Men also have a uterus. It's called the prostatic utricle, and it is a little pouch in the prostate formed from the rudimentary female genitourinary tract that all embryos begin to develop (Mullerian or paramesonephric ducts). There is also a small remnant that looks like a little bump on the testis in most men (testis appendix). Most of breast and nipple development occur after birth, or at least the epithelial component (the ducts and milk makers). Scientifically, this is one of the most interesting things about mammary development and remains a topic of active research. It is also the basis of a commonly used model of breast stem cells and breast cancer development: cut the fat pad of a mouse mammary gland before this has happened (~ 3 weeks old), then transplant your experimental breast cells into that "cleared" fat pad. True breast stem cells will form ductules that ramify throughout that fat pad, and can be harvested and transplanted to a second recipient (as opposed to some other precursor cell). (Pre-)cancerous breast cells will make ducts with unusual branching patterns and will overlap, unlike normal cells.

The prudish approach omits to mention that sex is for more than reproduction. It is a way to mutually enjoy time together, to bond, and to bring pleasure. Nipples can be very erotic. So why does this "morally correct" video omit the obvious benefits for everyone having nipples? Prudes....

He didn't say why men have nips. In fact it was more important to say why evolution didn't get rid of them. if evolution doesn't get rid of things then why is not all living biology crawling with bits of leftovers from all the stages we all were in as evolving from goo? Men have nips as just showing how close male and female bodies are in early stages after conception. Speculation.
Rocket Man (3 years ago)
Evolutionists are hilarious. They invent this absolutely psychotic, flawed idea to remove God from the equation... then they invent a whole new deity, called Nature. So, we all come from monkeys, do we? Why is there no fossil link? What happened to the hair, tails, and extra muscular strength? All are very beneficial traits, with no logical reason for your god, Nature, to get rid of them. I could make up hundreds of such questions if I bothered to put the time into it, that one is just an example of just how flawed and insane the religion of evolution is. They can't even write a complete fairy tale, they have yet to write up the start (How the universe was created - The big bang is fatally flawed, as most scientists know. Then of course, there's the creation of life - Apparently life popped out of nothing (You know, the same way you see it happening every day) and was self-sustaining despite the fact there would have been nothing but raw elements to feed it.) It requires 100x as much faith to believe in evolution, as it does to believe in Christianity (As the Bible teaches it, not the Catholic Church) Why I say Christianity, is because it is the basis of every large religion to this day, including Islam and Catholicism, which both take the Bible and cut and paste it to their liking. (The rest of the religions are either entirely baseless, or also have some roots embedded in the Bible, aside from Judaism which came before the Bible and no longer applies in many cases) And, unlike the religion of evolution, it offers a complete story that hasn't and will not be disproven.
Rocket Man (3 years ago)
+Liberals Are Insane Also, as I forgot to mention, the whole theory of evolution relies on carbon dating. Carbon dating is used to fit the pieces together to the "scientists'" likings, and it succeeds in doing so, more or less. Unfortunately, however, carbon dating has been proven to be flawed and useless countless times. Nobody who has used carbon dating for an extended period of time will be able to truthfully tell you that it's accurate. There are dozens of ways the results can be rendered incorrect, eg. carbon in the atmosphere, the surroundings of the object being tested, natural disasters, storms... the list goes on. It simply doesn't work.

It's not actually because evolution would rather leave them there than change our DNA. Evolution does not pick how we evolve based on benefits. Evolution is a blind process. The real reason is because we are all female first before birth.

V1ralB1ack (3 years ago)
@Jm Mac I'm not sure what you said in the first part but I do appreciate your explanation. On 2) are you saying we're hermaphrodites before we're born?  Yea saying "we come from females" is bullshit but when we are conceived don't we start as female embryos and then change depending on hormones and other fluids? I'm not sure what "verts" and "nat sel" means either.

@Jude Rhyme I was trying to beat some sense into @rewer earlier. I let people worship how they like. Heck, i'm probably the only person in my school that is not an Islamophobe. But I was just pointing out that he has some ground to stand on.
