Ibrahim Ahmed EVOLUTION IS A FACT BECAUSE THERE EVIDENCE FOR EVOLUTION. YOU HAVE AT LEAST 14 VIRAL MARKERS INHERITED FROM ANCESTORS YOU SHARE WITH CHIMPS BECAUSE THEY HAVE THEM TOO. THERE ARE ALSO FOSSILS GOING BACK TO WHEN YOUR ANCESTORS WERE LIVING IN TREES. SORRY IF THAT BOTHERS YOU BUT IT'S A FACT "IF ONLY COMPLEX SPECIES SURVIVE" WRONG. ANY SPECIES THAT CAN SURVIVE SURVIVES ALSO WHY ARE WE YELLING?
I've seen some nature documentaries were the females will choose a male who is 'weaker' as a father for her offspring and the producers explain this by pointing out that he wasn't weaker: he was albino or blind or missing an arm and somehow still alive and surviving inspite of this. even a creature with a less-intricate brain can project that if another animal is still alive inspite of its wierd colors or dsabilities, it is stronger than the ones that have all the arms and legs. she knows for sure that this male could survive without pigment or eyes. she can't tell that about the males who have all their eyes and pigment.
farley pants That's not how it fully works. Still, for example, there's a reason why female animals want to mate with the most colorful male. Colorful males are easier to detect. If a very bright male has made it till adulthood, it means he's a tough one (or intelligent one) and by extend, he posseses good genes.
I think we went from full on tournament and have slowly become more and more pair bonding over time. Just think about all the manginas and metrosexual males that seem to be getting lucky, this WILL trickle down over the generations.
He falsely states that most human cultures are monogamous, that hasn't been true until very recently with the spread of Christianity and Western thought. Before then, most cultures had people seeking multiple partners, via concubines, or multiple wives, etc. Generally there was some commitment, though. Hence why bastards are so frowned upon in many cultures, as are "deadbeat dads." So we're sort of in the middle, like he did say. We compete to get as many mates as possible, but generally we seek some form of commitment from them.
+SpadaccinoLuciano --- Islam allows up to 4 wives, and that's like 1.7 billion people who are potentially polygamous. However, polygamy is still extremely rare.
secretname911 Yup. A guy who gets laid a lot is dominant, probably has good genes, and is overall a better mate. A girl who gets laid a lot has low standards, probably doesn't know what's going on, and overall is a poor choice. It's a natural way of looking at things.
Cha0x110 Probably. Thats just nature. Nature doesn't realise the concept of condoms/birth control... so, I'm willing to bet, animals will tend to look down on females who get laid while they are pregnant. Because the male who had sex with her while she is pregnant will not have his child to bare. Also, if you have alot of children, you will barely have enough time to take care of all of them. Some males kill the female's children just so she can take care of his own children. Thats just nature. And we still have nature's way of thinking in us.
Found This channel a couple of months ago when getting into J.R.R Tolkien's work and I have to say I am truly astonished by the amazing quality of video for what only can be described as an injustice ratio of subscriber. Great content.

I've only recently seen them, but I feel I can safely say that you really do have awesome understandable content! Keep it up!

It annoys me so much when r/iamverysmart's and r/niceguys are creeping around complaining about how the feminists are toxic in the comment section and missing the point, when they are the ones only talking about something that nobody else cares about.

great video! just wanted to add the fact that male humming birds are smaller than females, because they often engage in flying stunts to impress the females.
Wait what? How? in most mammals species Males are Larger than Females LOL you need to checked google first about who is more dominated male or female first
Typically in mammals but, it differs across the animal kingdom. For example there are female spiders that eat make spider after sex (more physically aggressive), there are male fish that literately attach themselves to the female and then die and act as a seamen sack (less physically aggressive). Ah, nature, how beautiful you are.
I am entertained by the thoughtful way that the information was laid out, but i am impressed that the term "cock block" was included in an absolutely educational video. really spikes the entertainment value, but lowers the replay value for most venues. even so, these videos are consistently delightful and things like the casual slang make them so relatable and sincerely charming. thanks for making fantastic content. :)
One question. This video suggests that in general, males would be more promiscuous than females because the females put more resources into producing offspring. How then does it explain species with promiscuous females that mate with multiple males instead of being choosy? I'm not just talking about species where gender roles are reversed such that the males put in more parental investment but there are some species where both males and females can be as promiscuous as each other. I've also heard of experiments showing that females can also increase their chances of reproduction by mating with multiple males. Also both humans and bonobos can also have promiscuous females.
Yeah, this video just says males don't necessarily have to invest more than sperm into a baby, so lots of mating is better for males because of that. But female's and males both benefit from promiscuity in other ways. One way has to do genetic variation, the reason for sex in the first place. There's greater chance of getting a good combination there, depending on what the environment throws at them. 20 kids from one male may get redundant in adaptation to the environment. 20 kids from 20 different males is much better for potentially beneficial traits. And there's probably lots of other reasons. Regarding what you were talking about, guppy females just mating with multiple males can make them lay more eggs. Not a prolonged genetic benefit, something about mating with multiple males rather than a single male makes them make more kids. Here's that paper: www.ncbi.nlm.nih.gov/pmc/articles/PMC27698/ Even though there was the same amount of mating going on in both monogamous and polygamous treatments, the promiscuous ones has a higher fecundity. Weird.
+Jonathan Hartman Well with domestic cats for example. The rate of infanticide is high in cats. However if a female breeds with as many males as possible then the kittens have more males invested in keeping other males out, and therefore them safe. Also it offers, to species that have litters or clutches a larger diversity in genes for their offspring. Like cuttlefish. The big strong males dominate the mating. However smart small males pretend to look like a female and sneak breed the females. So the female wins out by having both strong and smart offspring, doubling the chance for her genes to be passed on.
+Jonathan Hartman 5:08 --> he's saying that generalizations are, in essence, not useful for predicting SPECIFIC behaviour. Additionally he mentioned behavior is influenced by both you're environment and you're genes... So basically, you're behaviour isn't determined by only who you are, what also matters is how you are socialized (raised).
+Jonathan Hartman Most of the time, when females are promiscuous, the males stick around to help raise the kids. This is the case for Tamarins, where the males do most of the raising. In that case, the more males she has, the more kids she can support. In other situations, where the male doesn't stick around, the female usually has some internal mechanism like a sperm storing pouch that lets her keep and choose sperm from lots of different males. In this way, she can make her selection later. In some sense, the promiscuous female is rolling the die and playing the numbers game. She may end up with offspring that are weak, but chances are good there will be at least one mate with good genes that she otherwise wouldn't have been able to mate with, had she been monogamous.
+Jonathan Hartman "This video suggests [...] how then does it explain species with promiscuous females that mate with multiple males instead of being choosy? " The video doesn't explain that - but you just did, quite well.
I just learned something new. thank you! No wonder why im so aggresive.. I was on the more dominant side than parental and definitely a tournament species by nature but with education and having to interact with people daily, its not good to have dominant/ tournament mentality thus pair bonding state of mind is a better overall. not to mention the harsh environment I grew up in, no wonder I am the way i am. thank you!
So, this is possibly impossible to answer (i.e. why does anything happen in biology), but I'm going to ask anyway: Why is the sex ratio of births still generally one-to-one? If the gene 'wants' to be reproduced more frequently then, it seems to me that a very advantageous trait would be to be able to produce a majority of females. If this happened then, over time, I guess the tournament traits would get de-emphasised because there'd be less competition, and a pair-bonding (or tri-bonding / poly-amorous bonding) would get emphasised. More females would mean a higher chance of the rarer males mating with multiple partners and ensuring more genetic spread, wouldn't it?
No not exaclty there are spevies where females very overwhelmingly make up the species and if you evolved into a tournament species it still carries on for many many generations like in many animals . I think youre assuming to much knowledge in aninal affairs or how evolution works . It doesnt alwaus make sense or whats good for the species. This whole idea animals behave for whats good of the species has actually been debunked no evidence for it. Please read robert sapolsky
i love this channel, you guys make science so much more funny and interesting than it would have been if you just said the facts, so keep up the awesome work!
"Let's pretend it's safe to leave a woman alone with your chocolate." What are you talking about? I have a nice piece of chocolate right in front of me right now. I nice delicious piece of chocolate..... Munch Munch slurp slurp...... damn it.
Lucien Richardson I know. I'm to weak. I very sorry. It won't happen again, I promise.... hey is that chocolate.? Munch munch.....wait......god damn it!
Why don't house cats have any significant dimorphism? I would think that their reproductive strategy is closer to the the tournament one. Does it have to do with humans selectively breeding them?
I'd say it's because of humans. I've noticed the pride of cats I feed (living out the country, it's cheaper than mouse traps) have large males. I guess despite the plentiful food, the stronger males take the females each generation.
And this is why we like skinny or muscular people so much. Skinny and muscular usually means healthy. This is also why men who have a lot of sex are considered studs while females that have a lot of sex aren't held in the same degree. Males tend to be expendable in the eyes of nature while females aren't. A female with no standards isn't going to be seen as a favorable partner. But this probably isn't universal. Not all species reproduce the same way.
5:35 it's kinda funny that it's supposed to be a grammar error, yet it's exactly how you spell "sex" in my language (we don't have "x", "q" or "v" in our alphabet)
I cannot wait to scroll down and see all of the rational people who are able to transcend their instincts in favor of a rational discussion of nature. I Just Can't Wait.
thanks! I felt it was too long. It is now the channel trailer. I might put another one in but I would want it to be 3-5 seconds long. Personally I like having no intros. Wastes precious precious time.
Another way (that i don't think happens in nature) would be to simply birth more females than males. if there'd be 1 in 10 chance of a male being born then male gametes would still be plentiful. This would mean that most males get to breed and the only deciding factor in a specific genes survival would be how well it helps SURVIVE. Alot of tournament species mentioned seem to be in an evolutionary dead end of sorts. It's an arms race among males. They need to be big and strong in order to breed their kids will need to be big and strong and their kids... If a lion was born that was 10% smaller but needed 50% less food to sustain itself he would never breed and pass this magical gene. And humans are neither big or strong, we are the dominant species that just happen to go the opposite way.
That tournament species thing makes sense, it's not neccesserilly that women only want the stronger lad, it's that usually the male that succeeds is usually a bully loool.. Until the present day when anyone can get it
Because we have testosterone. It is a hormone that influences our brains and causes us to act in different ways that will result in as many chances of offspring as possible.
Actually testosterone is what decides your muscle growth and aggression, I read a study a few years ago that showed that most of the hyper violent inmates in prisons are generally physically larger and produce up to three times the regular amount of testosterone.
Great video! Whenever I try to explain this concept to people all they hear is "Blah blah blah abstract, blah blah blah theoretical." Unfortunately every other person just puts their fingers in their ears and calls you a sexist.
I do really wonder why gay and bisexual people exist in our species though. Bonobos are a really close relative to us and they seem very openly promiscuous but at the same time we tend to disapprove of homosexuality even while we fairly commonly display it. I wish research could go into this without the intent of proving if gay people are real or fake good or bad but rather with the intent of proving a fairly neutral phenomenon
Akito IM ONLY UNICORN!!! AND I CRASH AND I BREAK DOWN IM ONLY UNIICOOORRN!!!! A WORD TO MAH HEAD A WORD TO MY FACE NOW HURRY UP BEFORE I FALL APART BECUASE IM ONLY IM ONLY UNCCORN!!! I WASTED LIKE 2 SECONDS OF UR LIFE
I think that this theory about the asymmetry in the costs of reproduction between males and females is the most important achievement in the study of sex. It was proposed by Robert Trivers in the 1970s, but until this day there are people that talk about sex and ignore it.
..I see what you mean when you say Humans are somewhere in the middle, I probably am, I tend to like a male who can fight off another male, but..I always keep saying I want them to do it with "Class" ..I guess by that I mean, I want them to put some smarts into it, to fight off another male and win my favour (if it works that way), using language and behavior skills, and not simply raw muscle. I tend to use cars and driving as a bit of a metaphor for that, so I guess I'll do that here too. If a guy were trying to compete with me using cars and driving, I wouldn't go with the guy who won simply because he could speed at 160-200 Kilometers per hour, because to me, that would put us both at a risk of getting into a serious accident and killing both him and me. If there were a guy who won because he knew the area and was clever enough to get ahead by using the right street(s), or was skilled at using a GPS to find his way around and get ahead, I would like him a lot more, because I knew if trouble arises that can't be solved by fists and physical aggression, I knew he could think of a solution, and I can also trust him to know his limits enough not to needlessly put his own and others' safety and comfort in jeopardy just to satisfy an antiquated sense of ego, there might be that old fashioned part of me that will be flattered by him taking a bullet for me, but there's a time and place to do that, and a time and place not to do that, I'd prefer any male I end up with to realize that.
I understand using brains in a fight. Had one in high school where I was basically using the idiot's rage and power against him. Purposefully get near a wall and taunt the fool, then dodge. Moron runs face first into a brick wall. In a fight, it's not so much about having the most power, but controlling the flow of power and energy.
sometimes i wish us humans, the human mating dance involved us males literally fighting another male in order to win over the female, in order to get a girlfriend, mainly because i feel its a way of kicking social anxiety's ass, approach anxiety's ass, it would be impossible to make approach and conversational error there, just me saying how much i hate how having shyness or just social anxiety is going to screw a mans chances of getting a girlfriend a lot more than the other way around
Well I hope youre not thinking males fight for females nowdays lol in humans this isnt the case lol humane males arent fighting over females and females mating with the winner lol humans are clearly not that simple. Many females dont care about fights lol dont make the mistake of making some failed analysts. We retained some traits but we are no longer a tournament species

So in conclusion, humans are the result of a tournament species trying to be a pair bonding species?...Huh.
This is so true! XD
I think we went from full on tournament and have slowly become more and more pair bonding over time. Just think about all the manginas and metrosexual males that seem to be getting lucky, this WILL trickle down over the generations.

In other situations, where the male doesn't stick around, the female usually has some internal mechanism like a sperm storing pouch that lets her keep and choose sperm from lots of different males. In this way, she can make her selection later.
In some sense, the promiscuous female is rolling the die and playing the numbers game. She may end up with offspring that are weak, but chances are good there will be at least one mate with good genes that she otherwise wouldn't have been able to mate with, had she been monogamous.
+Jonathan Hartman "This video suggests [...] how then does it explain species with promiscuous females that mate with multiple males instead of being choosy? "
The video doesn't explain that - but you just did, quite well.
Good video and nice art style. You should have more views.
This kind of stuff is going to be in my recommended for weeks now.

I just learned something new. thank you! No wonder why im so aggresive.. I was on the more dominant side than parental and definitely a tournament species by nature but with education and having to interact with people daily, its not good to have dominant/ tournament mentality thus pair bonding state of mind is a better overall. not to mention the harsh environment I grew up in, no wonder I am the way i am. thank you!
jacobmufasa life is cruel you either adapt or die( the basis of evolution), women think men have it all easy lol
Lol, i laughed so hard at the end (including the twilight parts)
I laughed so hard
So, this is possibly impossible to answer (i.e. why does anything happen in biology), but I'm going to ask anyway: Why is the sex ratio of births still generally one-to-one? If the gene 'wants' to be reproduced more frequently then, it seems to me that a very advantageous trait would be to be able to produce a majority of females. If this happened then, over time, I guess the tournament traits would get de-emphasised because there'd be less competition, and a pair-bonding (or tri-bonding / poly-amorous bonding) would get emphasised. More females would mean a higher chance of the rarer males mating with multiple partners and ensuring more genetic spread, wouldn't it?
No not exaclty there are spevies where females very overwhelmingly make up the species and if you evolved into a tournament species it still carries on for many many generations like in many animals . I think youre assuming to much knowledge in aninal affairs or how evolution works . It doesnt alwaus make sense or whats good for the species. This whole idea animals behave for whats good of the species has actually been debunked no evidence for it. Please read robert sapolsky
6:30 was so funny I laughed out loud.
The way he said it.
i love this channel, you guys make science so much more funny and interesting than it would have been if you just said the facts, so keep up the awesome work!
"Let's pretend it's safe to leave a woman alone with your chocolate."
What are you talking about? I have a nice piece of chocolate right in front of me right now. I nice delicious piece of chocolate..... Munch Munch slurp slurp...... damn it.
Lucien Richardson sorry. I really tried not to eat it. 😂🙈
Dude I've only eaten toast today, WITH NOTHING. And you go and do this, what a shame :(
Lucien Richardson I know. I'm to weak. I very sorry. It won't happen again, I promise.... hey is that chocolate.? Munch munch.....wait......god damn it!
Well... I just had some chocolate too... AT LEAST IM NOT A THIEF
Lucien Richardson I know. I'm a criminal. And I am very ashamed. But in my defence, it's chocolate!

Why don't house cats have any significant dimorphism? I would think that their reproductive strategy is closer to the the tournament one. Does it have to do with humans selectively breeding them?
I'd say it's because of humans. I've noticed the pride of cats I feed (living out the country, it's cheaper than mouse traps) have large males. I guess despite the plentiful food, the stronger males take the females each generation.
My male cat is significantly larger than my female one and they’re both the same age
And this is why we like skinny or muscular people so much. Skinny and muscular usually means healthy. This is also why men who have a lot of sex are considered studs while females that have a lot of sex aren't held in the same degree. Males tend to be expendable in the eyes of nature while females aren't. A female with no standards isn't going to be seen as a favorable partner. But this probably isn't universal. Not all species reproduce the same way.

Why did you remove the intro? i liked it. And thanks for another very interesting and informative video.
thanks! I felt it was too long. It is now the channel trailer. I might put another one in but I would want it to be 3-5 seconds long. Personally I like having no intros. Wastes precious precious time.

I searched up How to make a cat model in Z-brush and now Im here. Wow.
People often misconstrue this into meaning "men are violent and evil" when really they're just more likely to compete for mates.
Concise and informative. Good work.

This is a good presentation of sociobiology to educate the public. Nicely done!
Another way (that i don't think happens in nature) would be to simply birth more females than males. if there'd be 1 in 10 chance of a male being born then male gametes would still be plentiful. This would mean that most males get to breed and the only deciding factor in a specific genes survival would be how well it helps SURVIVE.
Alot of tournament species mentioned seem to be in an evolutionary dead end of sorts. It's an arms race among males. They need to be big and strong in order to breed their kids will need to be big and strong and their kids...
If a lion was born that was 10% smaller but needed 50% less food to sustain itself he would never breed and pass this magical gene.
And humans are neither big or strong, we are the dominant species that just happen to go the opposite way.
But then the females (in most species) would become more aggressive :/
HeWhoShamesNarwhals women can't choose what gender their child will be
HeWhoShamesNarwhals Cause we got brains :P
{cookiemonster} Stu:Dio ik lm late but they are talking hypothetically
Also late, but it's reasonable if the males are dying off because of conflict and predators.
That tournament species thing makes sense, it's not neccesserilly that women only want the stronger lad, it's that usually the male that succeeds is usually a bully loool.. Until the present day when anyone can get it
great video. for future videos like this: can you please make a bigger difference in the male/female drawings?
I honestly think humans used to be a tournament species and we just switched at some point
Because we have testosterone. It is a hormone that influences our brains and causes us to act in different ways that will result in as many chances of offspring as possible.
Actually testosterone is what decides your muscle growth and aggression, I read a study a few years ago that showed that most of the hyper violent inmates in prisons are generally physically larger and produce up to three times the regular amount of testosterone.
that twilight reference! lmao good job and thanks for the explanation XD
Why are some women louder than other women... lol!
And here comes nature vs nurture
Great video! Whenever I try to explain this concept to people all they hear is "Blah blah blah abstract, blah blah blah theoretical." Unfortunately every other person just puts their fingers in their ears and calls you a sexist.
love these videos. pumped for the next one
What about Sharks? the female great white shark is bigger than the male? Can someone explain?
its just opposite
+Edin Cvrk makes sense
that also happens with owls but both of those species aren't mammals so i guess its for different reasons
Bald eagles too.
Me being attracted to strong male is genetic, I can assure you. It does not come from environmental factors.
Once every 5 months
Correction- 9 months
The video doesnt say that it is humans.

I do really wonder why gay and bisexual people exist in our species though. Bonobos are a really close relative to us and they seem very openly promiscuous but at the same time we tend to disapprove of homosexuality even while we fairly commonly display it. I wish research could go into this without the intent of proving if gay people are real or fake good or bad but rather with the intent of proving a fairly neutral phenomenon

fun fact, women have more stamina then men
@KFC Man why wouldn't it be as true for stamina as for strength.
@KFC Man same with stamina,its just that some people have naturally more then others.
@KFC Man that actually is true
@@manticore2804 Men have more strength tho
@@wiseguy240Winston I agree, I don't know why girls want to be dominate so bad but God created us males to be more dominate
From my experience EVERY ONE IS NOT THE SAME
Jokes on the one guy coz the 8 guys were gay and dating each other💀
I think that this theory about the asymmetry in the costs of reproduction between males and females is the most important achievement in the study of sex. It was proposed by Robert Trivers in the 1970s, but until this day there are people that talk about sex and ignore it.

This is brilliant!
..I see what you mean when you say Humans are somewhere in the middle, I probably am, I tend to like a male who can fight off another male, but..I always keep saying I want them to do it with "Class"
..I guess by that I mean, I want them to put some smarts into it, to fight off another male and win my favour (if it works that way), using language and behavior skills, and not simply raw muscle.
I tend to use cars and driving as a bit of a metaphor for that, so I guess I'll do that here too.
If a guy were trying to compete with me using cars and driving, I wouldn't go with the guy who won simply because he could speed at 160-200 Kilometers per hour, because to me, that would put us both at a risk of getting into a serious accident and killing both him and me.
If there were a guy who won because he knew the area and was clever enough to get ahead by using the right street(s), or was skilled at using a GPS to find his way around and get ahead, I would like him a lot more, because I knew if trouble arises that can't be solved by fists and physical aggression, I knew he could think of a solution, and I can also trust him to know his limits enough not to needlessly put his own and others' safety and comfort in jeopardy just to satisfy an antiquated sense of ego, there might be that old fashioned part of me that will be flattered by him taking a bullet for me, but there's a time and place to do that, and a time and place not to do that, I'd prefer any male I end up with to realize that.
I understand using brains in a fight. Had one in high school where I was basically using the idiot's rage and power against him. Purposefully get near a wall and taunt the fool, then dodge. Moron runs face first into a brick wall. In a fight, it's not so much about having the most power, but controlling the flow of power and energy.
sometimes i wish us humans, the human mating dance involved us males literally fighting another male in order to win over the female, in order to get a girlfriend, mainly because i feel its a way of kicking social anxiety's ass, approach anxiety's ass, it would be impossible to make approach and conversational error there, just me saying how much i hate how having shyness or just social anxiety is going to screw a mans chances of getting a girlfriend a lot more than the other way around
Fr bro the way animals do it is so much simpler. I cant think of a single animal whos mating style is more complicated than ours
Well I hope youre not thinking males fight for females nowdays lol in humans this isnt the case lol humane males arent fighting over females and females mating with the winner lol humans are clearly not that simple. Many females dont care about fights lol dont make the mistake of making some failed analysts. We retained some traits but we are no longer a tournament species
