It's Okay To Be Smart : It’s about a lot more than X and Y… evolution insists on a balance. If you want to learn more about this bit of evolutionary theory, there’s some suggestions in the description. Leave a comment and let me know what you thought of this week’s video!

Mr. Dr. Genius : 0:43 You changed your clothes just so you could make that joke.

Sai Gungurthi : I love the elephant seal drawings 👌🏾😂

Science with Katie : This was super interesting, I read somewhere recently that as the male:female ratio is very off in China due to the one child rule and a preference for baby boys (I think it was something like 117:100), the bride price in China has skyrocketed. Bad news for the boys! Sidenote: loved the poem 🙊

Isak Hermansson : Beautiful poem at the end. More of those please!

Steven Baumann : That elephant seal thing 😂 I thought in humans there were more women than men. Thanks for the explanation. Now we need to genetically engineer us some purple people eaters.

Abage : *W H Y N O T ?*

Ricky : 0:58 will generate alot of ...ummh...discussion

Karel : So there are enough girls for eveyone? Even for me?! :´)

Feynstein 100 : Hmm throughout human history, men have been killing each other in truly staggering numbers. If the chance for a male vs female is indeed 50/50, wouldn't that have caused a huge deficit in the male population that could be observed to this day?

- Shooting Starlight - : Because everyone needs a soul mate! Lol shut up I'm a romantic

Navin xy : 1:51 I feel sorry for those (forever alone) elephant seals who even don't have hands ✌✌

Jo King : I think the more important question is, why do most guys still allow males AND females to act like there are only 10% females in the world.

Faben Tesfazion : I like the poem at the end.

SwePow : For such a "smart" channel, the comments are surprisingly dumb

Nisha Prabha : HIII

Kellastico : OMD, I’ve been thinking about this topic hard core for months now! I didn’t know there was an actual science to it

Albin Adolfsson : I actually havent thought about this. Really intressting, great video

Atanih23 : 0:56 - I appreciate this addition.

Nettle : Wow, people are actually angry because they took five seconds out of the video to explain the terms they're using to avoid confusion...

Salem Al-Arrak : Evolutionary Stable Strategies (ESS) is the topic that shifted my perspective the most when I read The Selfish Gene. Great video. I hope you can delve more into ESS soon.

Cap Made MY DaY : Because of my *Hand* it kills many *millions* per week

Mantas Gervinas : So there's a chance for me to find the one

Kobi Jenkins : That poem was great I’m just starting too I can relate Best of luck to you

Snivader : I thought there were more males than females in the world though, for a few reasons, but even removing parental preference i thought there was a bias, like 51 to 49 in percent. I dunno.

phanTomtilt Lira : I knew if I stayed up late something good will happen.

Top Ten Bangla : make a video on"why some river has two color of water"

drsquash2003 : So glad you clarified that definition of male female. We wouldn't want anyone's delusions to be shattered by scientific fact

Benjamin Nelson : SciShow has to specify biological sex now, and then draw a rather unscientific distinction from gender? Science is science, and politics is politics, bad things happen to both when you let them mix.

Nickos Moshovis : -Poetri got nailed! -Poetri? or my english? -No time to google poetri get in the freakin chopper -Chopper?

Paul Watson : "We're talking about biological sex, not gender." *rolls eyes*

Australian : Had to put a subliminal trigger warning in at the beginning I see. It won't help. People love getting offended these days.

chim chim : I don’t know... I mean thats why I’m here, to know

Cynthia Goodman : How do elephant seals avoid incest related genetic issues if such a small number of males pass on their genes?

Zantar 16 : China

Someone Anonymous : Because everyone wants someone to reproduce?

Greg M : Chinese men outnumber women by 33 million after decades of gender bias. In some areas it is so imbalanced these areas are now importing females from other villages and other countries.

Apelyn's Entertainment. : this video has 30 thumbs down. i don't see a single "offended" human being all i see is idiots ranting about pc culture and how there are only 2 genders and whatnot and wtf. just because he clarified that he means sex... for 3s. what

Das Ganon : I'm curious though. Sure in Mammals and Birds sex is determined by chronosomes, but what about some reptiles? They have their sex determined by temperature. How do they get about 50/50? Will this be a problem in the near future?

Martin Owens : If 4% of Elephant seals are responsible for 88% of matings, then that leaves 12% of matings spread somehow between the 96% remaining seals. Yet the video claims that 96% of seals never mate, which is mathematically inaccurate according to itself.

Jojo Garcia : Does this also apply to insects such as ants and bees, and arachnids? 🐜🐜🐜🐜🐜🐜🐜🐜🐜

Dan B : >denies science w lefty euphemism @1:00 down voted

KappaW : Let me explain this to everyone who doesn't understand. The reason clarifying biological sex is being spoken about and not gender is so crazy is because gender has been seen to simply mean "style". The clothes you wear and how you present yourself is "gender", it has nothing to do with science and is just a sort of fad that was created by a bunch of nutjobs called intersectional feminist. The idea that gender and biological sex are somehow related is akin to saying that chemistry and alchemy are related. Technically yes both chemistry and alchemy are related but its a superficial relation at best, the same goes for Biological sex and gender. Now on top of these facts, there are many cases of individuals who are huge proponents of "gender identity" flat-out denying science. Going so far as to say sex doesn't exist and its all a big lie created by society and every single person on the planet can choose whatever sex they want to be. There are literally people who believe this, I'm not making it up. So you can see from what iv said that casually relating the two of them on a youtube channel dedicated to hard science is a pretty damn disturbing thing. I won't even go into all the extremely controversial politics involved with gender identity either, but its there. Now I see some people who are honestly confused about why people are upset, and I understand if you have been totally unaware of the things iv stated above it would be confusing. But understand that whats going on here isn't just some blind hatred of opposing views. In fact, we are totally against the idea of blind hatred and are willing to discuss anything in a fair and reasonable manner with healthy discussion. It just gets tiring having to explain what already seems patently obvious, so some people just downvote instead of taking the time to write an explanation like I am. Can you blame them honesty? I sure cant, and I hope anyone who reads this has a better understanding of whats going on here. A real discussion is a healthy thing!

Reyhana Patel : Sorry, nothing to do with this episode, but the other day, my kids smeared toothpaste on the bathroom mirror, I wiped it down then I went for a bath, strange though, afterwards I noticed that the corner of the mirror that had had the toothpaste smeared on it didn't steam up, whilst the rest of the mirror did! Any scientific reason why?

Marta W : Kinda nice of him to mention genders (im not trans or anything, just found it nice)

Andrew Tidey : So you’re saying incels had a point

yeleminpino : " It's 2018 now, I have to be ridiculously politically correct 0:57 "

Magma Grunt Jaiden : "It's worth pausing here, because we are talking about biological sex, not gender" I LOVE YOU SO MUCH. I am non-binary and people like me are constantly met with prejudges from society. I am so glad some people know how to differnciate between sex and gender.

CosmeFulanito476 : "we are talking about biological sex, not gender" oh no, not this channel too please no........

bksoldier90 : 0:58 So wrong!!! If you decide to change your gender you suddenly become the other sex...
