Maybe we should add this note every time we talk about biological sex on SciShow. Here's the thing, there are definite and dramatic physical differences between biological males and biological females. There are also psychological tendencies and cultural expectations, and those things are in the mind and in culture and so fundamentally come down to individual experience.
Because of that, gender has recently started to be considered separately from biological sex. This seems perfectly legitimate to the entire editorial staff of SciShow, and we are happy to discuss biological sex in a way that recognizes the existence of transgender people.
There are also a number of (probably not as rare as you think) intersex conditions in which people's biology does not fall into either of the two sexes.
For these reasons we don't find it inconvenient or extraordinary to separate gender and biological sex. We understand that this will cause discussion, but we appreciate the discussion being thoughtful rather than ideological, if that is at all possible.

SciShow there are only two genders
tbird81 but he didn't, he said "people with ovaries" not "girls" he's not forcing someone who is biologically female to comply to their birth sex so he's not telling you who they should or shouldn't identify with
It's just describing what it effects, peoples ovaries, which is what they are explaining in the comment above
Also y'all need to chill, it's just phrasing
Gender is, but not completely separate from sex, however for some people it is as with GID or gender dysphoria. The science is out there. Everything that involves life including the way you feel about your gender does have a biological basis whether your gender matches your sex or not. For instance, the levels of testosterone present in a developing fetus does have a good correlation for determining what it is you identify as when he/she becomes older (notice I don't use other pronouns). Though it is only my opinion, I do not think there is a whole gender spectrum of infinite genders. I keep it simple, just 3, agender is technically an absence of gender so absence = none = 0 so 3+0=3, but I don't know if it is real. Or maybe 2 as transgender people identify with male or female, so 2 genders?
I would *love* it if SciShow did a video on this topic. Just as long as they do not start saying things like there is infinite genders or millions or something.
:)
JTelk woman can be born without ovaries, some men/woman are born with both ovaries and testicles, some are born with infertile ovaries. There's so many complications that can occur with one's physical sexual reproductive organs they just found it easier to say "people" not this more than 2 gender bullshit you're trying to bring up.
SciShow
It really doesn't matter enough to make a substitution like that. Just say 'women' not 'people with ovaries'. The former means the latter.
We say 'mammals' instead if 'animals with some hair, endothermic body temperatures, and the ability to give live birth' even though there are some mammals that don't match all the criteria. So think of it that way.
I always wondered why it's called menopause when it's never resuming. It should be menoend.
Also, I love my grandma. She's 94 and still awesome.
We have a proverb in my country: "None is dearer than the child, except for the child's child", seems to fit well with the grandmother hypothesis.
I didn't even notice Hank say people instead of women... but now that everyone mentions it, I still don't care. This is not a priority for me, I am way more interested in the science explained in the video.
Thank you!! For fuck's sake, if the word "people" being used to refer to women offends you, I guess you can go back to ancient Greece so you don't have to acknowledge women as people at all. We won't miss you.

I wish everyone had this mindset!

if someone's born deaf do they still have an inner voice?
Chase Palmer hmm…
+Chase Palmer * Hits blunt *
If they learn sign language at early childhood, yes, they do have it and it's based on the sign language they've learnt. If they aren't taught sign language, they might not develop an inner voice, which might seriously hamper their brain development. I believe there's a SciShow episode about it, if I'm not mistaken.
Chase Palmer yes they do, just not in the way that hearing people do. As hearing people rely on spoken language to become their inner voice because they rely on hearing, deaf people rely on sign language to become their inner voice, as they rely on sight. So essentially their inner voice is a visual of sign language.
Smorgasborddd i know this is a bit extreme but what if they are deaf and blind? Would there thoughts be textures?? Or smells?
I thought he was gonna say this episode of Sci-Show would not exist without our grandmas.
Wel i guess that is true
But why do humans have periods? Most mammals reabsorb the uterine lining. But we don't. Why?
Because God hates us.
J.J. Shank it sure does feel like that when it's that time of the month again. It is also why I don't object the notion of a "male" God. I would hate to think that a woman would put other women through something as horrific as a period.
you'd imagine it would put our species at a big disadvantages because of monthly annual blood loss
I mean running sucks
swimming sucks
kiss leg day goodbye, hello chocolates and warm pillows from the dryer for 3 to 10 days ;-;
Actually, you only lose a tiny tiny bit of blood during your period, just enough to color it a bloody color. Most of it is the mucus lining of a female's uterus along with some tissue and other little things. It's kinda like how passing gas stinks horribly, but it's only because of a minuscule amount of sulfur. Only a minuscule amount of blood, but everything focuses on that
+BlackDawnYaoiLover That's true, some people make a big deal about how much blood women lose during menstruation. But it's more like, what, a tablespoon or two a day? I've given myself papercuts worse than that!
"close encounters of the sperm kind"..
Keefe Spence ahhhhh nice pun there xD
Keefe Spence aye.
Hank actually says it around the 0:49 mark and I just quoted it because I thought it was hilarious. Glad to see others agree!
my favorite part of this video is that Hank said this
Walk yourself out.
Well, now that you've broached the subject of menopause, it would be great to follow up on what causes the side effects, such as hot flashes, mood swings, night sweats, etc. Menopause is no walk in the park.
Hot flashes, mood swings, and night sweats and hot flashes are all caused by a lack of sex hormones stimulating certain parts of the brain. For instance, hot flashes happen because your hypothalamus does not have enough fuel to work as well. With that, your body can do one of two things: The first, and the most common, is that your perception of hot and cold is altered, so your body, not receiving the right signals from the hypothalamus, starts sweating to compensate, which can then turn into a cold flush as your body swings the opposite direction. Secondly, and more rarely (something I got) is a permanent increase to base body temperature. For mood swings, it's because there are estrogen receptors in the area that help modulate your mood. Without the sex hormones, that mechanism doesn't work as well either.
I've been in early menopause at 37, a neurology nerd for 20 years, a neuroendocrinology nerd for 5 years, biology for 32, and have been a menopause activist for almost four years.
@@maggiekelley259 what is a menopause activist?
I thought that since reproduction takes a lot of energy that when we reach our mid 30s to 50s that it gradually goes down the priority list because our bodies need the energy more to stay alive.
I love how inclusive Sci Show is in referring to people experiencing menstruation or menopause. This was 3 years ago and they were already two steps ahead of the game. Greatly appreciated 👏🏽👏🏽
As a Grandma who adores her grandchildren & has been supporting SciShow for many years now, thank you Hank!
Let's give this vid a round of meno-plause!
It's actually very uncommon to see a young man talking about menopause without a medical degree.
"liberals get so easily offended" yet 70% of the comments are just non-libs getting razzled because Hank said "people with ovaries"
Inda B they're so dumb, even if you don't agree with the "gender" thing, not all women have ovaries
King Aesthetic like who?
Women born with Sawyer's syndrome; they don't have ovaries or produce estrogen (or a decent quantity of it). As well as women who are simply just born without ovaries or a complete set of reproductive organs, it's the same with women who are born without a vaginal opening.
There's also women that have had their ovaries removed due to cancer.
@Eddy Skeleton according to your theory we should never say people have legs because they are some people born without legs. Some are born with brain falling out of their skull. Do you want them included as well?
Unless explicitly specified always healthy people are meant. Both what you and I say are not healthy people.
By any means I don't address the general issue here with sexes and genders but this comment just hit me with it's pointlessness and that's what I'm talking about.
I thought the science in this video was fascinating. Thank you, SciShow.
I definitely studied the grandma hypothesis for my Bachelors degree in Anthropology.
grandmothers are a treasure!! wish i still had mine!!
I watched this video entirely because I had read hank's blog post on it, and really didn't notice the lack of gendered language, but as the sister of a female-to-male transperson, I know it goes a long long way. Thank you so so so much scishow team.
My grandma raised me so HELL YEAH GRANDMAS! Let's go!
I love being a grandma. I think I offer something different than my daughter & son-in-law to my granddaughter's development.
"Close encounters of the sperm kind" lol
deee DEEEE dooo bwah BWAH!
Because sometimes women just need a pause from men.
True.
@@fivesix3868 it needs to be called Menostop ! Menopause implies that they could get periods again ...
For the rest of the life
i will never get enough of your videos!! thank you so much for helping us to learn in this effective and simple way
I live with my Granny, I love her to bits.
This was really interesting. Most information I've seen about the menopause concentrates on the physical aspects of periods stopping but not the reason why this happens. The only theory I had heard before was the non adaptive theory so it was very interesting to hear other possible explanations.
What if we're all secretly whales?
You ever hear of the aquatic ape theory? Afaik it's been debunked, but it's still fun to think about. Basically the idea goes that there was a line of primates that lived and hunted near the ocean, and we're one of their evolutionary offshoots. The idea was meant to explain why humans and cetaceans have so many traits in common, like menopause and a diving reflex, that other close primate relatives don't have. Hell, there was even a fake documentary put out several years ago (called Mermaids: The Body Found) citing the aquatic ape theory and saying another one of their evolutionary offshoots was literal mermaids.
Oh good grief. Why the heck is the title such a big deal? There isn't anything inherently wrong with the way it's worded.
I really don't think this hullabaloo would be happening if a similar title was made for a video about another species.
Ex. 1 "Why Do Cats Have Barbed Penises?"
Would everyone really get upset just because the title didn't specify MALE cats? I think not. We all already should know that. It's implied by the topic being covered.
Human is a normal way to refer to our species, and with that being said, menopause is a characteristic of our species even if not all members EXPERIENCE it.
Men may not experience menopause, or any other of the explicitly female traits, but they do carry the genetics for these traits within their own DNA. That's why they can pass down reproductive traits from the women in their side of the family to their daughters.
This is an excellent point. The fact that people react to this title at all demonstrates that people tend to think of male as the default sex of a person. Sometimes in a really weird and obstinate way.
The question "why do humans build houses?" makes complete sense and is utterly innocuous even to a person who's never built a house in their life, which is most people. Building houses is nonetheless characteristic of humans, as is menopause.
"people born with ovaries" bless this channel
I really appreciate the inclusive language used here. Thank you.
Video: /doesn't say "women"
Most of the comment section: /HFBGFT TRIGGERED
WireMosasaur Apparently getting triggered has become some sort of a competition lately
WireMosasaur but why DOESN'T it say women in the title?
because he was talking about the human species as a whole? why do so few mammal species have menopause? that's really what the video was about
have you noticed that he mentioned "females of whales, elephants, etc." but "humans with ovaries"? if you don't understand what is the issue, then you are not that smart as you might think.
How is that an issue Alex?
I would love to see an updated version of this video! I’ve seen recent science that says that the risks of complications/losing a pregnancy are not actually a significant increase. For instance, a change from .5% to 1% - which technically is doubling but in context is not a big change
I'm gonna throw this out there and say that the title says human because it is actually comparing human menopause to other species. If we were comparing human females having menopause to human males not having menopause, that'd be an entirely different video.
the issue is not the Humans in the title, but the "Humans with ovaries" compared to "whale/elephant females".
Alex Grey I understand that too, but the majority of the complaints I've seen in the comments have been about the title.
The reason they made that distinction is because transgender people exist. Every human who has ovaries doesn't necessarily identify as female. However, animals don't have gender identities, all they have is biological sex. So a female animal and an animal who is able to give birth (at least when it comes to sexual reproduction in mammals) are the same thing.
49jubilee well there are also people females without ovaries, or genetic males with ovaries. It happens and the simple thing to do is to just be scientifically accurate, which in this case actually coincides rather well with inclusive language.
For many videos now whenever scishow talked about females and males they used the term bio-sex female or bio-sex male. but I noticed they only really used those terms when talking exclusively about humans, which is not the case here. it's just a different distinction since the ovaries are what are actually needed biologically for female puberty and menopause to occur
Expected people discussing the video normally. wtf is going on?
Always interesting, thank you.
Super interesting! I love this show!!!
To clarify the title "Why humans...." is referring to the fact that not all mammals experience menopause.
That's not what people are arguing about...
wooly mammoths also went through menopause, according to the biopsy of a frozen corpse of an old female found in asia

I love this channel! whiteout it i would not understand how the universe works so I passed my fysik class
^^ cool coincidence, is my grandma's birthday tomorrow.
*Calm down y'all, they say 'humans' because the question is why menopause occurs in **_our_** species but not in almost every other species on Earth?* -> as in Why do humans but not dogs (or insert almost any other species) have menopause? - 'Why do women but not bitches/hens/queens/females of other species have menopause?' would sound ridiculous 😂

Hi there, SciShow! I would love for people to learn about the terrifying and sudden nature of cerebral aneurysms! I had one rupture at 19 and I think it would make for an interesting video topic!
Would you shut up about it!? Constantly spamming every video with the same comment will cause them to not do want you want.
Well it worked for that stupid pubes comment.
Because, it's weird that a mother has a sister/brother younger than their children.
nature's way of preventing us from literally covering the whole world with humans lol
killer whales are a species of dolphin not whale. the name killer whale is just badly translated and should be "whale killer".
Whales are the Infraorder of Cetacea, there was split from baleen whales (Mysticeti) and toothed whales (Odontoceti). Killer whales (orcas) are a part of the toothed whales (Odontoceti) but so are sperm whales and beaked whales. They are closer to dolphin then whale, share a superfamily, but toothed whales are closer to Orcas then baleen whales, biologically speaking.
Killer dolphin sounds terrifying though
As a non-native English speaker K have to learn what you're talking about before I can learn how it works. I had no clue what this video was about before I started watching. But once I figured that out I knew exactly what it was. This happens so often with your videos xD
Animiles lol
You're the kid that thinks his dad has menopause
Imma nerd watching SciShow😂 but I love it✊🏾💯
I naturally went through menopause starting at age 39. I'm 44 now.
"people with ovaries" As a woman without them, thanks for phrasing it that way. :)
LexieAssassin yass🌈
I'm with ya there, LexieAssassin.
Are you really that insecure?
Scishow, thanks for the inclusivity. It was subtly, smoothly, and respectfully done. Sorry the comments section is a mess, but many people appreciate it more quietly than the trolls are yelling.
I always thought menopause was related to the increase of chance that the fetus could get disabilities, therefore restricting birth at a specific age would be a safe guard. But what do I know
I do want to thank Grandmas. They are amazing
"Why do humans have menopause"
Because there is some entity in this world that pities us and gives us 40-50 years of peaceful living
Im guessing it's both reasons. Longer lifespan is why menopause appeared, probably in many species. The grandmother thing is probably why it stuck around in a few species. In most species though evolution would select for females that had a longer fertility and could have babies later in life because they would produce more offspring over a longer time.
Worth noting though is that it has stuck around in apex predators. Killer whales and humans are pretty much at the top of the food chain. Maybe when generations aren't directly competing for resources older, individuals will contribute more to the pack with their skill and experience than they cost to maintain.
Look at humans, most people are well done having children when they reach 40, but they still contribute massively to society for decades after that. Humans especially where we not only raise our own children but benefit and educate the entire population.
but there are literally only three species that menopause and alot of whales are as long lived as the porpoises
That's why I think menopause is(or would be) selected against in most species.
The older individuals that could not reproduce would be a burden on the species. Because they would compete for the same resources as the next generation, and probably would be better at it than their grandchildren at least initially. So the younger individuals in the pack would be less well of and would have a harder time to feed their own offspring when they were outcompeted by their elders. This would mean a smaller population growth as there simply were less food available for the babies.
Evolutionary pressures would probably select against the menopausal animals since their packs would have fewer offsprings than packs were older individuals actually did continue to reproduce during their entire life cycle.
However in species that hunts in packs the older menopausal individuals might actually be a net benefit for the pack as a whole. Yes they would still take a slice of the cake that could have gone to the next generation, but their skill and experience would mean an overall bigger cake.
In a specie like this menopause might actually be selected for rather than against because that would mean that the experienced individuals would spend more time benefitting the whole pack rather than focusing on raising their own babies that would do less good since older parents often leads to more health problems in their offspring. Hence "the grandmother hypothesis".
Also in a species were older moms would not mean more health problems for their children, menopause would not be selected for.
LarsaXL you dont see this behaviour in other dolphin species who are long lived and pack hunters. it would be interesting to see if wolves get menopause if you increases the length of life to 80 years or so
True, yes that would be interesting. It might not have appeared in some long lived species because just a longer lifespan is not enough, the lifespan needs to extend past the potentially fertile lifespan. For humans females have enough eggs in them and cycle for long enough to be fertile to around 50. If human lifespan were around 45 years menopause would not be a thing except for unusually long lived individuals. It makes sense that an animal would be fertile for at least the average lifespan of that species, plus an extra buffer. So while average human lifespan would be around 30 it still made sense to have enough eggs to potentially be fertile to 50. Dolphins and many other long lived species might simply not have extended their lifespan more than their fertile span, maybe both have increased. If menopause appear at the end of the lifespan it will probably not be selected fore since it only happens to individuals who are about to die anyway and so the "grandmother benefits" will not be very pronounced. But humans have extended their lifespan way past their fertile span. Many people live well into their 70:s that's around 20 years longer than their fertile span. And you can do a lot in 20 years. Raise a grandchild well into adulthood for one thing. Another very useful thing is to have old people staying at home, using a lifetime of experience to craft better arrows, better traps, better clothes and amass knowledge about medicinal plants that greatly benefits the young people being out there hunting and gathering. They could also teach and educate the young generation and take care of children. In really desperate situations they could also defend the tribe during a raid while the young women and children hid or ran.
That's at least true for humans, people with a lot of spare time will use their curiosity and creativity to tinker and try to find out how things work, and to make them work better. They might nerd deeply into a subject and become an expert, experts are very useful, and they generally love to talk about the thing they love so they make good teachers, or at least spreads that knowledge around. Or make great art, tell stories and maybe even create religion or administration that helps the tribe to cooperate better.
Raising children and gathering food takes a lot of time, and having people around who don't need to do either can be a huge benefit. So menopause became a thing in primitive humans. Because old people didn't just die when their reproductive days ended, they stuck around for a decade or so more and did other things.
This at least is why i think menopause evolved among early humans, as far as killer whales are concerned there might be another reason. Or maybe the beginning of the same reason. Killer whales are not tool using, they don't build shelters, record history, but there might be other tasks in their packs that are best left to adult individuals who are not spending all their time raising children.
Wow this was quite long, see spare time encourages people to think, speculate and further knowledge, or at least debate.
LarsaXL but killer whales are highly intelligent even for porpises so it could just be social intelligence that is important
"Around age 50, periods get irregular" - thanks to genetics parameters, cause it's happening around age 40 for me! YAYYY
Shouldn't it be called Menostop? Menopause makes it sound like a temporary condition.

Honestly, I think it would be a kind of funny running joke -- as long as it's not ruined to the extent of the "Why are there _____ around my anus" jokes -- to say something to the effect of "Why didn't you just say women instead of _____" on the occasional new SciShow video.
"Why do Humans have testicles?"

"Why do killer whales do have menopause but elephants don't?"
"NO, ONLY FEMALE KILLER WHALES DO HAVE MENOPAUSE AND MALE KILLER WHALES DON'T!!!! KNOW YOUR BIOLOGY FACTS, YOU STOOOPID IDIOTS!!!
The question was, why humans as a species got a certain characteristic and elephants as a different species don't have this trait.
The human body is too hot for semen. So that's why testicles are outside where it is colder. Also that's why you shouldn't put your computer on your lap.

uterus cancer at 42 instant radical hysterectomy menapause. complete hell .
male humans can experience the same symptoms around that age. My mom currently has some of those symptoms, but my dad also has them. Not as severe as my mom though.
All humans change as they age, menopause is different as it has an exact meaning. To stop having periods and not longer be fertile. Men never have periods and still have fertile into their 70s or even 80s.
L O His soldiers aren't marching anymore? I guess his sperm is not affective anymore.
I'm not sure if its my computer or the video, but the white grid lines behind Hanks head seem to be doing strange things as he talks.
Scishow is gift to humanity!!
Apparently women are not humans if reading the comment section is anything to go by.
Nothing implies that, it is an unnecessary linguistic choice within the video, not the title, that issue is being taken with. At least, that's my issue. If the issue of others is with the title, they are in the wrong.
really idiot? people arnt saying a woman doesnt classify as a human, they are saying menopause and periods are a woman thing, not a HUMAN thing. men dont have periods, therefore men dont go through menopause, the stopping of periods. such stupidity baffles me
the only thing not human are youtube comments
Yale Benson lol no
+Cuzeg Spiked man come from old english meaning person, the word woman did not exist and man were not use to say a human male and no, man were not tough of being superior against woman, it was only some greek that i am aware were thinking like that
I cracked up every time he said "We go through menopause" like he is part of the WE.
if im not mistaken, people with male reproductive organs also go through a form of menopause, but instead of it being with periods/female reproductive organs, it has to do with hormones and sperm
How do i wake up a minute before my alarm?
Hooray for grandmothers! :D
Y'all are seriously going to complain that he said "humans" instead of "women"? We're comparing species, not genders or sexes (which are different, which is also why there is non-gendered language in the video). Honestly I don't see why being inclusive/general is such a bad thing other than people wth narrow world views and no empathy afraid that the status quo might change. Sorry. Norms will always change eventually.
just.........call them........orcas........
one of my grandmothers died one year before I was born. the other we cut of contact with when I was 1.....
Would it be possible to prevent menopause? Either through genetic engineering or some other treatment feasible in the long-term. As medical technology gets better and we are able to extend human lifespans further, the proportion of a (biosex) females life were she is able to easily have children is likely to decrease e.g. if people regularly live past 150, and you assume that 18-35 is the optimal time to have children, then thats just over 10%. I'm sure that would have societal and demographic ramifications.
Additionally, post-menopausal people have some negative health outcomes, I think post notably in terms of bones, but I'm not a doctor...
"Why do humans have XY chromosomes?"
Why do birds lay eggs?
Surpuppa Why is water wet?
Surpuppa why is the sun dry?
Guys, he's talking about how the video mentions something restricted to 'women'(here he uses a male example) but says the general term 'human'.
And I was bringing up an example of how we usually don't use sex or gender if we talk about the characteristics of a species.
Hence "Why do birds lay eggs?".
That you did not even realize that I did not say "female birds", even though male birds don't lay eggs, should work as an example for the usage of species names to describe sex-related characteristics that species have. Other examples would be:
"Anglerfish hunt with light."
"Cows give milk."
"Kangaroos carry their young in pouches."
I have no idea, what the other two did, though :D
"People with ovaries". If only we have a name for them.....oh wait
Violet Rose there is. people with ovaries.
Violet Rose or are people who have had a hysterectomy not women anymore?
Emily. Don't talk. A hysterectomy has nothing to do with your ovaries. It removes your uterus. An oophorectomy is when the ovaries are removed. Do your research.
me n jiji my point still stands. just because I got the term wrong does not negate that. and I will talk if I damn well please, thanks.
Emily McAwesomepants also, trans women have no ovaries and trans men do! intersex people may have them or may not, so non gendered language is used in this video as not everyone who has ovaries is a woman! sorry that other person was so angry with you but it's a rather touchy subject, as some women have had their ovaries removed because of health risks and no longer feel like true women, and trans people are often never talked about or accounted for and it can be rather upsetting.

I was in perimenopause forfuckingever! I _finally_ reached menopause, at age 50, and the weirdest thing happened! My curly hair is now growing out straight! 😱 After googling, apparently, this is normal, going from curly to straight, or the other way around. I already HATE how my face and skin have changed, but now my hair, too?! WTH?!?!
Getting old SUCKS!
I didn't even notice he didn't say "women" until I looked at the comments. Does it really bother people?
Humans used to not live as long as we do today, so we have just the right amount of eggs for the amount of years we would have lived without the technology and advancements we have today. That's my guess anyway.
Pasta Farian interesting but doesn't explain why men can still reproduce
Pasta Farian yeah... they talked about that, its called the Non-Adaptive theory...
Pasta Farian that is the funny part of this, at birth a women has enough eggs to sustain a one egf consuming period a month for over 400 years...
Except that humans have lived to at least their 70's for a long time. Long before our modern technology. People living to a 100 was perhaps more rare but certainly not unheard of. Our old people today haven't been able to benefit nearly as much from modern living as younger people have. Yet, more and more people live past 100.
Question since changes in dna of cells causes cancer is it then possible for your immune cells to become cancerous themselves?
can u plz do a video on the giants caseway in ireland
Is there a theory that menopause helps humans (woman) live longer? If you are stressed, your body stops the processes that it thinks are "unnecessary " so maybe the body stops using "unnecessary" energy for the menstrual cycle and starts pumping blood to the heart more
Jamaica Skeepers the heart is the thing pumping blood..... lol
Bruno-Thanks for clearing that up for me....
Your body does what it is designed to do. The word "stress" varies a lot depending on how you use it. For example you could be stressed out by having the wrong color on your curtains in the living room. While someone else could be stressed out because they're starving to death in Africa. Which stress do you think is the "worst" one out of those two?
LoFloW 6 didn't seem like she realised xd
Also, after a certain age, the female body may be too weak to support and bring to term a pregnancy. Perhaps the bodys are protecting themselves.
When he said "humans with ovaries", I knew I was gonna find a comment war down here.
Chill my fellow humans, you'll get used to it.
gender occupation
"Chill my fellow humans, you'll get used to it."
Get used to what? Anti science bullshit being passed off as facts even though there is no debate in science that in fact only women go through menopause, because gender as something separate from biological sex is bullshit.Humans can adapt to all sorts of wrong things, including people pushing bullshit as being correct, heck that's the basis of religion: Just because we can get used to it, doesn't mean we should. I for one have no plan to bend over and take it from people who are deliberately misleading people on science, for the benefit of what is essentially a secular religion.
Used to the use of scientific terms that respect the identity of other human beings. Which terms they used should be "anti science bullshit"? "Ovaries"? "humans"?
Also, this video was not about women, it was about the human race in contrast to other animals.
Religion is based on faith and one of its key features is that it does *not adapt* its way of doing things if new evidence shows up.
"Used to the use of scientific terms that respect the identity of other human beings."
Sorry but no, you can't do both, you either state objective reality, or you attempt to comport reality into a pleasing fiction that makes snowflakes feel better. You can't do both, so pick one: Are you going to call the things the things they objectively demonstrably are, or are you going to lie and obfuscate by pretending that those things are actually something else."Religion is based on faith and one of its key features is that it does not adapt "Actually no, religion adapts all the time, that's how religions end up with doctrine they build new bullshit on top of the old bullshit. What it doesn't do is self correct when provided with evidence. So EXCACTLY the same as this anti-science bullshit, being passed off as science.

by that logic, scishow made no mistake.
I used to think that it was due to running out of eggs. Apparently not. I suppose it might be due to decending to the use of less viable eggs, but that's weak.
I recommend you do an episode on the new invention that uses zirconium crystals in a box to produce 3 liters of water per day from the desert air
Hank made a good science video
-Nobody cares
Says "Humans with ovaries"
-Everybody loses their mind.
I think this PC thing is kind of dumb but does not make the video worst or less scientific. People with ovaries have menopause, humans have menopause, where is anything subjective? I didn't even realized before reading all the shity coments.
Sorry for the bad english, still learnig it 😔
Your English is actually a lot better than that of many native speakers.
The non-gendered language of this video is hecka validating and helpful and I love you folks at SciShow for this xxxx
Valaquesse erasing woman is ever more classy
Shove your validation up your ass you fucking genderclown
As a non-woman that will likely go through the menopause; it's just nice to feel included. Reproductive stuff makes me dysphoric as heck. So I was overjoyed watching this video.
I don't want to erase women; I want to erase the gender binary that restricts everyone.
Third wave feminism is hard.
What the fuuuuuuuuck!!!! What the fuck is happening to Western society?
Jay West - moving forward?
Granmother hypothesis is real! The childdren are more likey to survive and grandmothers live longer.
my kneejerk response is: maybe other animals would have a menopause but just don't live long enough to? I mean did we become menopausal as soon as we became human? If you treated a chimp well enough could it live long enough so you could find out? hmmm :s
Mmm how about this idea: It's to prevent the Futurama situation: As in having sex between a grandparent and a grandchild (minus the paradox of you being your own grandparent)
For longer lived and tightly social knit communities it might be more common to end up with inbreeding, which could create various genetic problems; probably more so if a parent/child mating occurs let alone a grandparent/grandchild mating.
Animals of course don't innately know the problems with inbreeding, so evolution would probably end up favoring those mothers who naturally became sterile with age; they'd still be around to provide the benefits of experience, but be naturally be pushed out of the breeding cycle. This of course only applies to those animals who do end up inbreeding. Those who do not wouldn't have this problem and there wouldn't be much harm in being able to breed throughout the entire lifespan of the animal.
Just a theory at any rate, and the evidence out there probably contradicts this assumption anyways!
