Human Males Evolve At a Faster Pace Than Females
Tisha_AH writes "A report by the Whitehead Institute indicates that the human Y chromosome present in males is evolving at a furious pace. Across the chromosome there can be as much as a 33% difference within humans alone. The portions of the chromosome evolving fastest are related to sperm production."
The cynical among us might say that we're finally catching up...
Males masturbate more than females, amirite?
Al least some scientific data ;-)
Very seriously, I had a feminist girlfriend that wouldn't believe a child sex was defined by the spermatozoid. According to her the female genitals were as much responsible for the sex of the child.
I guess this article explains everything, she needs more evolution in order to understand those advanced concepts ;-))
Everything I write is lies, read between the lines.
I wonder if this would counter the other studies saying that the y chromosome is doomed.
Mod the whole article flamebait. The headline plays with the common association between "evolution" and "improvement" in order to gather angry responses and its fair share of taunting.

You're correct, males do tend to generate more sperm than females...

Males are not an independent population. And individuals don't evolve, so the notion of evolving males is silly.
Evolution is something that happens in a population, not in an individual. The female part of out population likely benefits just as much from the continuous changes to the Y chromosome as the male part of the population. Evolutionary speaking, that is. It's unlikely any individual would really care.
"Darwin Award" winners are pretty overwhelmingly male.

What is it already, about us and our testicles? Anyway, no wonder women look at us like we're mutants or something.
At least that's how they explained it to us in BIO 101. (Yes I realize it was probably a massive simplification.) The idea was that the Y chromosome has almost nothing on it and is little more than a female to male switch. (All the info for creating a male body are else where in the genome.) If that's sort of correct that means it doesn't really matter if the Y chromosome changes since all it has to get across is the signal "You male, UGG" Anyway if us guys evolve so quickly where are all my super-powers? (You know, besides my super power to turn green lights red when I drive up to them.)
Did you know 80 to 90% of the moderators on slashdot wouldn't recognize a troll even if one dragged them under a bridge.
You know the womens groups will come out that this is sexist? I swear it's like the religious groups who come out with their nonsense when science disproves one of their "theories" - you know like the earth is not flat, does not reside in the center of the universe, and is not approximately 6000 years old.
I remember, in highschool, writing a science paper and basically went about that the strongest man is stronger then the strongest woman, and the average male strength is greater then the average female strength. That physically, men were superior to women.
It caused an issue in school, and I was called into the principals room. So where my mom and dad. My dad was pissed...at the principal. My mom just thought the principal was an idiot.
Now there is this article, stating men evolve faster then women. I remember, a few years back, showing that men have a greater affinity for science/math, and women more for culture/literature and this extends beyond the nurture part of nature vs nurture.
FYI: The universe is not equal. The world is not equal. The genders are not equal. It's not fiction, it's not sexism, it's fact.
I do not support "The Man". I also do not support your irrational stupidity
Uhh maybe a less sensationalist headline?
To mate, must make happy one of the opposite sex. Now, the requirements for men are far more complex than for women.
TFA doesn't say there's 33% variation among humans. It says there is an unexpected amount of variation between human and chimpanzee Y chromosomes.
The article doesn't entrely match the summary, especially the title. It says little about the evolution of the X chromosome, only that the Y is evolving faster than they thought it did. TFA makes no comparison between the X and Y chromosomes. There can be in inferrence, as it mentions that the Y has no chance to swap genes as the other chromosomes do.
It also infers that it's the chimp's Y that is evolving more, and the "better" is sperm production, and it's the difference between how chimps and humans mate. One female chimp will have many sperm donors, while most human females don't.
So rather than saying that men's sex chromosome is evolving faster than the female's X, it could be said that chimp's Ys are the ones doing most of the diverging.
Free Martian Whores!
"Evolving" might not be the right term. "Changing" might be better. Simplistically explained, so don't hang me for this: Evolving is genetic changes that is the result of environmental pressure. Evolving therefor results in better adaptation and superior individuals. Any disadvantageous mutation quickly perish. Very few changes are beneficial.
If there is no or little environmental pressure, any non-lethal mutation survives, and mutations flourish, good and bad.
If the rate of mutation increases rapidly, it is either due to intense environmental pressure, such as arriving on the Galapagos Island, or it is due to the fact that there is no environmental pressure on this genetic treat, and you survive either way. Literally Degeneration.

They compared the speed of evolution of the Y cromosome in men and chimps, which compares men and chimps, not men and women. Women have no Y cromosome, so how could the speed of evolution of the Y cromosome in men say anything about men in relation to women? That's like saying that the Adam's apple in men evolves faster than the one in women.
What I would like to see is a study done on the size of the clitoris in women compared to the one found in chimp females.
I hate this 'Slow Down Cowboy!' shit, let me post already!
This is why I appreciate being a scientist. Science has its way of continuing to tell women, "Get back in the kitchen, and make me a pie".
"Darwin Award" winners are pretty overwhelmingly male.
Evolution is driven by mutation. The vast majority of mutations are not beneficial. The fact that these Darwin Award winners are male only adds evidence that males are evolving at a faster pace than females.
Fortunately, in order to truly be a Darwin Award winner, you must remove yourself from the gene pool. The Darwin Awards show that evolution works!
There is no "I disagree" mod for a reason. Flamebait, Troll, and Overrated are not substitutes.
This has been known for a long time. It is called "male driven evolution". This happens because in humans (and most animals) the cells producing sperms divide about 6 times more than the egg cells. And guess what: studies in a human gene that has a homologue in both X and Y chromosomes, showed that (you guessed it) the Y homologue changes about 6 times faster than the X one.
Did I say old news? 1947 old:
“The primordial oocytes are mostly if not all formed at birth, whereas spermatogonia go on dividing throughout the sexual life of a male. So if mutation is due to faulty copying of genes at a nuclear division, we might expect it to be commoner in males than females.”
“ we should expect higher mutability in the male to be a general property of human and perhaps other vertebrate genes.”

I don't mind dating a girl that has been with everybody, as long as she had a good shower afterwards.
testicle size in simians is correlated with female permissiveness. such that, in chimpanzees, where a female in estrus is pretty much a gangbang, chimpanzees males have evolved humongous testicles. they need to, because in such a situation, the only strategy available to the male to ensure his genetic continuance is to simply overwhelm other male's sperm with sheer ejaculate volume
meanwhile, in highly monogamous simians who mate for life, such as gibbons, the testicles are tiny. there's simply no need for so much ejaculate volume, its a waste of resources. she's not going anywhere
interestingly enough, human males have intermediate sized testicles, owing to the fact that human females are semi-monogamous/ semi-polygamous
however, i've always wondered why testicles appeared on the outside of the male mammalian body. it seems a ridiculous vulnerability and i've never heard a good explanation as to why. for example, dolphins aren't swimming around with their balls out: the need to be streamlined. of course sperm need a lower temperature to develop, but thats an effect, not a cause. i'm saying wouldn't it be better to have your testicles inside your body and evolve sperm that develop at a higher temperature? its pretty ridiculous to have such an important organ dangling outside unprotected. i never understood why

Yes... and no. The "differences" you mention are not hard, sharp divisions. They are bell curves with peaks in different places, but there is lots of overlap. Even in the realm of sheer upper-body strength, I guarantee that (unless you happen to be a champion powerlifter) there are are women who can outbench you.
It's not that differences don't exist. (They do, and vive la difference.) It's just they they are of a different kind, and a different size, and a different range, than you seem to understand.

Floating face-down in a river of regret...and thoughts of you...
The whole idea of evolution is that you have differentiation through physical isolation. It is very possible that, due to nationalistic and cultural considerations, we have actually successfully used our minds to create defacto pockets of isolation. These pockets, would indeed have different mutations, and ultimately, could even speciate!
This is my sig.
Apparently size does matter.
I still cannot find the droids I am looking for...
But isn't this kind of obvious?. Changes that effect reproduction should happen the fastest. I mean isnt that what evolution is all about, getting better more efficient ways to procreate?
CS: It is all sink or swim...oh and did I mention there are sharks in that water?
Well that's what you get for using non error correcting memory err... DNA. The y branch does not have a second table to look things up in.
Also if I'm not mistaken we also evolve to get rid of this evolution since the y branch keeps getting shorter. At some point they will be v chromosomes :)
Men are the testing area :P Y chromosome is the development brach, X is the stable?
Not fast enough, since we haven't evolved winged sperm yet. We basement dwellers may be a dying breed!

I've calculated my velocity with such exquisite precision that I have no idea where I am.
The Darwin Award only applies is the organism is childless. And most dangerous behavior exhibited by males is primarily tied to mating. Far more men get into bar faights over women than all other reasons put together, and many of those reasons are tied to copulation in some way (money, etc).
Free Martian Whores!
are you telling me evolution can't figure out how to produce sperm at body temperature?
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Many years ago, I read a serious genetics paper about this. The scientist managed to setup up a colony of fruit flys (drosophilia melanogaster) so that the females remained static - they did not evolve - and the males did.
In fruit flys, multiple males mate with a female, so there is a lot of competition between the different sperm.
What happened is that the males evolved their ejaculate to become more aggressive, to outcompete the other males; in some cases, the ejaculate became toxic to the females.
1st off i'm not going to cite stuff because i've not got it at hand and any citations would be from audio files. the recent courses i've listened to in biology and, more specifically, evolutionary biology suggest the y chromosome is a shrivelled up little thing fast loosing genes. as a guy i didn't much like hearing that either. there's some evidence in some flatworm species that 'penis fencing' suggests bearing young is an "aggressive act" foisted upon a weaker rival. how that would scale up to other species i couldn't say. there are recent findings that male sperm have complex mechanisms that try to induce the egg to draw down from the female as much developmental resources as possible while the egg has similar mechanisms that will try to limited the amount of resources a fertilised egg can demand of the mother. this seems to suggest that there's not only great complexity in development but that sperm and egg are in competition. it's very complex not yet nearly understood stuff. also a 'faster' rate of evolution isn't necessarily a sign of good things to come or an evolutionary edge. what i term differential evolution, for want of a better term, seems not to have been studied or made available to mere lay people such as myself. by differential evolution i mean what does it mean when a species evolves faster. does it simply mean the species has greater fitness? what are the consequences of 'faster' evolution and can such consequences be considered in anything but out of context, almost trivial generalities?
ideopath @ play
I'm waiting for my apology.
"The portions of the chromosome evolving fastest are related to sperm production"
Men are furiously coming up with better and better ways of getting laid. A trip to a local bar could have told you that.
...sperm superiority is so important to successfully passing on an organism's genes that the best sperm, the ones that "win" and partner in producing the zygote, carry along even detrimental traits, since the chromosome is taken as a whole. No wonder Nature works on improving sperm more than anything else. (Now cue the obligatory jokes about detrimental, or radical traits, all coming from the male.) (Actually, there is some truth in this, since the Y chromosome cannot swap out its defective or its suboptimal parts with its pair, since it hasn't one, which accounts for more idiots AND more geniuses among the male vs. the female population.)
Those are my principles, and if you don't like them... well, I have others.
In Soviet Sweden sex is said to be a social construction. Research like this must be buried.
Comment removed based on user account deletion
but WHY? why do the testicles need to be outside the body? it seems to make no sense: you have a vital organ dangling outside the body. should we also carry our livers in skin pouches out the side of our abdomen? should our spleens be held in little sacks on our chest? does that make any sense to you?
OBVIOUSLY there is a good reason for it, evolution has produced us to be this way. but what is that reason?
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
I'm a male, as I suspect you are, and that was my first thought as well (so maybe we are), but then I realized that this can probably be explained by the fact that there are many more geeks in the world now, and we are all trying to figure out a way to get laid ;-)

Guns don't kill people; Physics kills people! - John Lithgow as Dick Solomon on Third Rock From The Sun
It's worth noting that you can make a complete human being without a Y chromosome. Its main function is to just signal the production of the sex hormones necessary to transform the (by default, female) fetus into a male. In fact, Y chromosomes have been shrinking for some time across species, indicative of the relative importance of their mere presence versus their negligible contents. It may well be that the higher mutation rate is a byproduct of cells saving energy by not doing much repair work on a chromosome whose contents are largely irrelevant.

A Male is not a population. The set of all males is a population referred to ... wait for it ... as the population of males. It turns out the word "Males" is plural. Who'd a thunk it?

It's more of a taboo to make fun of dead females. Same with domestic abuse and sexual violations. That's not owed to feminism btw - it was like that long before feminism has appeared, it just stuck around.
Evolution favors those that can reproduce faster and in greater numbers not those that are intelligent and/or strong. From what stupid crap I see on break.com (which should be renamed OwwMyBalls.com), I don't want males to dictate the course of evolution.
From now on it is going to be no I'm right because I am more evolved.
Just because you are wrong and I called you out on it doesn't mean I am a Troll.
"Apparently size does matter." - by Low Ranked Craig (1327799) on Thursday January 14, @09:55AM (#30764056)
Per subject line above, and your quote?
"Size matters"??
Well - Yes, it does (& to human females in only 2 main REAL areas):
1.) Size/width of male's wallet (i.e. -> How much wealth, & thus, power, does the male have)
&
2.) Size of the male's "pencil" (as well as how you write your name with it, so-to-speak).
You do ok in those 2 areas, and you should be alright.

I hope that we are evolving towards a chocolate-flavored sperm.
Evolution is not always a beneficial change. There are plenty of evolutionary traits that resulted in dead ends for some species.
The related articles off of the MIT site point out that the Y chromosome has areas of replication that can make the entire chromosome or parts of it fold back upon themselves, creating non-viable offspring.
The idea of the article points out that there is much changing in the Y chromosome and it does not have the mechanisms in place to prevent some of the gross errors in duplication.
I was careful to not use the word improvement in the title. Maybe some folks cannot make the distinction between an evolutionary change and an improvement but I can.
In some ways cro-mag was superior in design to modern h-sap. A shorter body build, better musculature, larger brain case, improved sinus design, etc.. But they still died out or were out-competed by h-sap.
We do not know what the relationship is between genetics and autism. Maybe (my speculation here) autism results from the human brain being turned up way too much.
Tisha Hayes
As the Y Chromosome is a genetic dead zone filled with genes that don't do anything. The overwhelming majority of these changes are probably useless mutations that have no effect on the host organism and therefore didn't get bred out as harmful in the same way a mutation on the X chromosome would most likely kill the organism in which it expresses.
Think about it, we are 2 percent different genetically from chimpanzees, which accounts for the what we see as dramatic differences between our species, but this study found 20-plus percent genetic differences between our Y chromosome and our closest ancestor. Men are not 20-plus percent different from women as we are 2 percent different from chimpanzees.
The word "evolution" has nothing to do with this study. There is no natural selection involved, only random mutations amassing on a chromosome that is mostly empty space anyways.

Sperm and egg meet to form any individual.
There should be a 2-fold factor between regular and Y chromosomes due to "extra divisions". Your chromosome 21s, for example, are half dad and half mom. The dad one is mutated 6x more than the mom one (if your numbers are accurate), they then cross over & become more or less 3x. Meanwhile your Y chromosome undergoes no crossing over and stays at 6x.
Haldane got a lot of things right and a lot of things a little bit wrong, as most great scientists do (esp. after 60 years)
Wonder if all this talk of estrogen in water supplies could be one of the reasons for the changes in the Y chromosome. I remember an article about males fishes actually turning females because of this very reason.
Did they take marriage into account?
After marriage men don't change but women do.
Of course most people here on /. wouldn't be familiar with that concept outside of 2L.
If someone is passing you on the right, you are an asshole for driving in the wrong lane.
Caution! I am in no way qualified to answer this...
Anyway, I've wondered that same thing about the external testes, and here's my theory:
The placement of the testicles is not to give the individual male a survival advantage, but rather to place an evolutionary force on the population as a whole. When a male is overly stressed and/or insecure his testes are withdrawn and close to the body. It is well known that this makes sperm production lower because of the body heat (this is why fertility doctors will recommend against tight underwear!).
God I hope this means we could be leaving behind those aspects of the american ideal of masculinity that I find most wearisome. I know i'm operating at the level of pop meta-science here, but god it would be nice.
When did soldering become dangerous? A minor burn risk maybe...or did you mean soldiering, ie military service?
it's use for population control isn't just for conspiracy theorists anymore! Using evolution to destroy the human race is evil! Jesse Ventura said so ... I dare you to contradict him! Unless you're Chuck Norris in which case I just say "neener neener" so you can understand me.

"It's called self-deprecating humor. I'm a male, so I get to make fun of men."
Assuming you're a man, saying "all men are stupid" deprecates you --- that's 1 person --- and 3 billion other people.
It's 3 billion times more *other*-deprecating than self-deprecating.
Not saying racist and sexist jokes aren't funny.
But they're not self-deprecating.
Needing the teller to belong to the group the joke targets, ain't about self-deprecation on the teller's part. It's about what sort of things an audience is prepared to listen to, and from whom.
And your logic isn't so great either. The fact that the Y chromosome is changing more rapidly does not mean that "males are evolving more rapidly than females". Here's a hint: entire male human being != Y chromosome. The Y chromosome represents a pretty tiny amount of genetic material, and doesn't have much of a function other than to control the development of male sexual characteristics. To say that men as a whole are "evolving more quickly" because a tiny amount of their genetic material changes at a faster rate than the other 45 chromosomes is, frankly, kind of dumb.
But hey - coming up with a more accurate headline wouldn't drive as many page views, now would it.
... but this is just dumb on its face. First of all, it's really hard to argue that plastic surgery has "drastically reduced selection pressure" on women, when even today, not that many women actually get plastic surgery (relative to the female population). Second - who's most likely to get plastic surgery? Women of child-bearing age? Or older women? You get one guess. Finally, what basis is there to assume that, say, having a boob job makes you more likely to bear more (or fewer, I can't quite figure out your argument) children? Given that anyone who can afford plastic surgery can also afford birth control, I think it's pretty unlikely that there's any correlation at all.
I know that most here believe evolution IS a fact, but just wanted to point out the the so called scientific experiment done is predicated on the foundation that evolution is a fact. So uses the conclusion at your own risk.
I think you're correct about society's portrayal of men, which is frequently pretty bad. But let's not blame the women's movement. I read a couple of feminist blogs, and in addition to the expected coverage of discrimination against women, they spend a fair amount of time bitching about these stupid "men are stupid" portrayals. Just today in Broadsheet (which is part of Salon), there was a post demolishing some dumbass who had written an opinion piece to the effect that male contraceptives were a waste of time because 1) men were too dumb to remember to take them, and 2) no woman would ever be able to take a man's word that he was on the "male pill". So yeah - that stuff is out there. But actual feminists are about freedom from sexual stereotyping for everyone... not just for women.
I'd mod you up. I wish people could understand that feminism isn't some kind of zero-sum game that involves women achieving superiority over men. The end of silly sexual stereotypes is good for EVERYONE.
The idea that rapid changes in the Y chromosome is somehow the equivalent to "males evolve faster than females" is 1) unjustified by the article, and 2) just plain dumb on its face. But given the choice between an accurate headline and a headline that will draw more page views... the choice is obvious, right?
Let's face it, everyone initially starts off as a woman but only a select few of us are chosen to evolve into something better. We're just better species with the better chromosomes.
If we evolve to have vaginas on our hands we may very well wipe out females.
We're making it tastier for the ladies?
Relax, fellow male people. Have you even read the article? It is about chimps, not human Y chromosome evolving. The human was the one compared against. Read the rest of the article and you will be enlightened to know how nature works to provide competition advantage for the most coming of chimpanzee folks. I hope same kind of evolution would not be necessary for humans, BTW. [quote] By conducting the first comprehensive interspecies comparison of Y chromosomes, Whitehead Institute researchers have found considerable differences in the genetic sequences of the human and chimpanzee Ys... [/quote]
It could simply be taken as a form of compliment - specifically, by way of self-deprecation.
"Self-criticism is in fact self-praise. It shows how much one can spare."
In this light, political correctness can be seen as just a reflection of the victim's continuing powerlessness.
Males are genetically weaker -- having considerably greater vulnerabilities to genetically-inherited conditions like color-blindness and autism. There's nothing exceptional about the Y chromosome evolving slightly faster. It would only make sense for it to happen that way because men are XY and women are XX, there is always an X passed on. Because of the exclusivity of the inheritance of a Y chromosome -- it can only occur in XY males or in genetic deformities where the person is XXY, etc. -- it means that there's more chance for certain traits to just be discarded. Because there's more chance of having a trait just discarded, there's a stronger state of genetic Darwinism in effect. Despite the faster evolution, men are still much more vulnerable to certain genetically-inherited conditions, so there's obviously still a long ways to go.
Male primates have a Y chromosome which is far smaller than the X chromosome so the impact of a constant mutation rate on the Y in contrast to the X should be that Y genes have higher probability of mutation than X over a given period of time. Evolution is partially mutation rate dependent ergo evolution of the Y proceeds faster.
Seems pretty obvious yet why did people imagine the Y was stagnate? Magic DNA in Y that is immune to the laws of chemistry and physics with regard to mutation rates?!
"Contrary to a widely held scientific theory that the mammalian Y chromosome is slowly decaying or stagnating, new evidence suggests that in fact the Y is actually evolving quite rapidly through continuous, wholesale renovation."
There seems to be a lot of stuff in biology that is too superficially examined to pass the laugh test. One-Gene-One-Phenotype is another one of those that was so obviously going to be wrong, simply based on graph theory. Then again, why do many people chose biology as a science major? Avoiding math! That's a good part of the problem right there.
You can't compare the evolutionary rates of males and females by comparing between the X and Y chromosomes.Both males and females have X chromosomes for one. The X chromosome doesn't necessarily determine female-ness, while the Y chromosome has the SRY (Sex-determining Region of Y) gene that determines male-ness. Evolution of the X genes affect both sexes, while Y genes only the male. Of course it'll look like they evolve faster.
Oh man the feminists are not gonna like this one.
Maybe they could catch up if they didnt spend so mich time crying and bitching...
How do you do*,
and please pray tell us all what you think one names it when something is still mutating and mutating fast?
Imminent death or evolution good Sir, imminent death or evolution. It would not be perfunctory to exclude the inappropriate interpretation for the sake of clarity rather than the rousing of trolls.
* Please kindly excuse me for feeling English today. At a location reached by crossing the sea north-east of Scotland one occasionally gets a penchant for this sort of thing out of an odd combination of demure nostalgia and the mirthful appreciation of the inherent beauty of it. I will now take leave to cure this through perusing some British comedy on the old interconnected network or perhaps instead indulging in some illustrated animated comedy from the furthest of the far east will do fine. I would think either will do in their curious commonality within the art of humour.
Good day to you :)
The title presented is a bit misleading. If you read the article it states that it does not necessarily mean men are evolving faster. The conclusion is simply that the one chromosome is evolving more quickly. Evolution of humans is more complex than looking at a single chromosome.
