I see that theory about female selection being pushed a lot lately, but it's a fairly easily debunked theory.

Female selection didn't occur in human society. Females didn't get to choose who they married. Rather it was the men who decided which females marry which male.

Also, there is far less diversity in the Y chromosome than the X. The best possible explanation is during ancient tribal war, the winning side killed all the males of the losing tribe and bred with the females.

Also, we have evidence that the greatest genetic winners are warriors/leaders like genghis khan and charlemagne.

Historical, genetic and biological evidence debunks the female selection theory.

As for the "pruning of violent individuals by the whole group". That too is nonsense. It is the most violent group who establishes order. Law and order isn't anything the group decided on. Rather law and order is something a small group of violent elites forced on the masses.

Think about the US. The group didn't vote on independence. Rather it was a small group of violent elites. During the revolution, at most 30% of the colonial population supported independence.

Think about the current world order ( aka international order ). Nobody voted for it. It was forced on the world by 2 world wars, 1 cold war and 200 million dead people.

Or look at china. Tens of millions of people died in order for order to be enforced on that gigantic nation.

The idea that female selection or pruning of violent individuals is how humans tamed themselves simply isn't true. Also, the idea that humans tamed themselves is simply a lie as well. We were tamed through law, order and lots of violence. Also, full bellies and distractions ( bread and circuses ) helped.

To suggest that female selection simply "didn't occur in human society" is just nonsense. Utter nonsense. Over what evolutionary time period are you prepared to make this bold claim? Assuming you agree that females do select mates now, when in your opinion did the female-selection revolution come? Presumably it was already well established by the time Homer wrote of Penelope selecting suitors nearly 3 thousand years ago. And once established, how long did it take for women to evolve their current acutely sensitive awareness of male mate fitness?

Miles of copy have been written about mate selection strategies in humans and other species - it's a game of exquisitely delicate game theory, with complex strategies evolved over millennia. It's an arms race of epic proportions that is a fundamental driver of evolution. Our biology is shaped by it - women have concealed estrus, for example, as one more play in the intricate dance of information warfare that is mating.

But no, you casually dismiss it all as a "fairly easily debunked theory", somehow (?) supported by the fact that millions died in China in the 20th century.

If you feel like dipping your toe in the vast ocean of science you just flippantly wrote off, https://en.wikipedia.org/wiki/Mate_choice is a good place to start.

Homer also wrote of Helen of Troy who was abducted and raped by Paris. Also a major western history stems from a couple of ancient greek warriors fighting over booty ( aka women they got from conquest ).

Also, Penelope didn't choose the least violent man. Her criteria for marriage was the most masculine man who could use Odysseus's bow and shoot an arrow through twelve axe heads. So even if you are correct, my position still stands.

If you want to argue that female selection within narrow limits occurred, then so be it. That's not much of a selection. Using that reasoning, two male lion brothers taking over a pride, killing all the cubs and giving the females the option of mating between them is female selection.

I can't believe you are using greek myth and myth based on "nobility" to argue human selection. Maybe it's just me, but a british princess given the choice of marrying a german prince or a french prince doesn't represent "female selection" to me.

As I said, we have genetic evidence ( less diverse Y chromosomes ), historical evidence and biological evidence proving that the dominant evolutionary cause isn't female selection. It is males dominating and keeping their competitors away.

Look at the genetic "diversity" of mexico after the spanish conquest. Nearly 70% of the Y chromosomes are from european ancestory, 30% of the Y chromosome is from native ancestory, nearly 100% of the X chromosomes are from native ancestry. Do you think it was by "female selection" or the fact that spaniards brutally ruled over the natives and had the power to kill and mate with whomever they wanted?

A disproportionate portion black male Y chromosomes in the US are of european ancestry. Do you think it was because black slaves had a choice or because the white male slavers with the power had the power to have their way?

Do you think the genetic makeup of the US is a result of native female selection or because of conquest, genocide, rape, etc? Do you think pocahontas asked to be kidnapped, taken from her baby and her native husband and shipped to england?

Whatever female selection occurred happened within a male mating framework. That's my point. And the overarching driving factor in human evolution has been driven by males. You can't explain human history without it. You can't explain the current geography without it. The US isn't mostly white because of female selection. China isn't mostly chinese because of female selection.

Females did select, in multiple ways.

First, they sometimes cheated.

Second, arranged marriage is normally set up by people who largely share DNA with those getting married. (the parents negotiate) Since the DNA is pretty much the same, genetically it's as if the bride herself got to choose.

Third, opinion of the bride was not universally ignored.

1. Both partners cheated, I don't know enough historically to say if one gender cheated more, but I'd guess it's pretty even in monogamous cultures and in non-monogamous cultures there usually was a dominant gender that was permitted to be non-monogamous and the vast majority of these allowed non-monogamous activity on the part of males (I'm including having multiple wives here once dedicated relationships entered society, not just non-binding relationships, that last category was actually, to my understanding, dominated by female choice, but it's a very tiny sliver)

2. I don't see how this favors either gender in particular, outside of the general trend of a society to be more matriarchal or patriarchal (and most people have lived in societies that have skewed towards the patriarchal end)

3. I agree but given the skew of societies I'd say that the opinion of the bride was ignored more often than the opinion of the husband.

There are comments all over the place so I'd clarify my overall point, it appears that male-driven choice and female-driven choice have both contributed, neither gender was entirely sidelined or even close to that state, but from what I've seen male choice has traditionally had a larger voice in terms of reproduction. So females did select in multiple ways, (anyone who says it's all males is being silly) but their selection power was below the selection power held by males.

I think you missed a very important detail: Everything you wrote talks in terms of groups. There's a cutoff level of aggression past which individuals wouldn't be able to function as a group.

Evolution doesn't work in terms of positively selecting the "strong", it works by selecting out the "weak". In this case, the point isn't that we positively selected the most peaceful. Instead, we selected out those so violent they wouldn't even be able to organise into a tribe.

> Evolution doesn't work in terms of positively selecting the "strong", it works by selecting out the "weak".

This is incorrect. Evolution works by a differential in the rate of reproduction. If weak couples have three kids (who survive and reproduce in turn) each, while strong couples have seven, then there is a strong selective pressure on "strength" and the population will grow stronger and stronger over time, but nobody's getting selected out. Weaks are an ever dwindling share of the population, but in absolute terms their numbers are constantly growing.

And this kind of thing is common, as with selection for higher fertility and lower age of first reproduction in the New World.

But "tribalism" predates humans. Living in groups is a trait that humans inherited, not something we developed.

Now we may have refined it and grown it to form tribe of tribes, but the point still stands.

When it comes to humans, we have to talk in terms of groups because that's the human experience. Humans don't exist outside of a group. Humans never have existed outside of a group. The "group" is what we inherited from our non-human ancestors.

Also, my point isn't that we selected the most peaceful. It's that female selection isn't the drive force behind human "evolution" or the human "taming". Humans were tamed through sheer brutality and concentrated power along with bread and circuses.

Take away the bread and circuses and loosen the concentration of power and I doubt we'd be as tame as we are now.

Domesticated isn’t the same thing as non-violent or even ‘tame’ as the term is usually used. It doesn’t even mean civilised. Rottweilers are domesticated. A small pet dog ate half the face off its owner, while she was alive, in France when she collapsed at home and it got hungry, yet it was a normal domestic pet dog.

I would agree that communal group living as seen in many primates is a precursor to the sort of domestication we’re talking about here. It’s a first step on a long road.

Yes Genghis Khan was violent and brutal, but he was also an inspiring leader that built alliances and administered a vast empire. He ate his meals using utensils, at regular times of the day, was able to be cordial and open minded about strangers.

He was first and foremost extremely disciplined and self-controlled. He was able to be taught and trained as a child, learn rules and commands and was able to control his immediate biological needs and desires especially when under external discipline.

Even that isn’t the whole story though. Cows and pigs are domesticated and display all the adaptive characteristics that come with it.

I didn't say domestication was the same as non-violent or "tame" or civilized. I didn't even mention the word.

My point is that humans were tamed through brutality and force and bread and circuses. And just like you little dog, when we run out of bread and circuses or an authority, we are capable of being violent again.

It seems like you want to disagree with me but everything you wrote agrees with me so I'm not sure how to respond.

Female selection of males is a thing. If it weren't, the subject matter of most popular culture would not be roughly 80% romance and relationships.
I originally wrote "female selection didn't happen much in human society" but changed it since those societies were rather fringe and aren't the dominant human society.

I know there were pockets of it. I remember watching a documentary on a small chinese ethnic group that practiced matriarchy and polygamy. But that's not the dominant nor the successful human society.

99% of human beings live in a patriarchical society. China, Europe, Americas, most of africa, Middle East, etc.

Edit: Here is the PBS documentary if anyone is interested.

https://www.pbs.org/frontlineworld/rough/2005/07/introductio...

And the chinese ethnic group.

https://en.wikipedia.org/wiki/Mosuo

True.

Most of the matriarchies were in Africa, and they were decimated completely when European colonizers showed up.

There were a few matriarchies elsewhere, but not many.

Most human societies were patriarchies.

It would be interesting, from a purely scientific point of view, to see what the african matriarchies would have developed into? How does that sort of thing affect development? Etc.

Men are shaped, in their most formative years, by their mothers. That's nearly universal.

Consequently, you may want to consider Ghengis Khan's and Charlemagne's mothers... those two ladies, due to the manner in which the raised their offspring, had their genes spread throughout a good portion of the planet.

None of what you wrote debunks female selection theory.
If females don't get to choose who they mate with and breed with, how would female selection theory work?

If tribe A conquers tribe B and kills all the males in tribe B and breeds with all the females in tribe B, how exactly is female selection involved here? Or even if the males in tribe B weren't killed but all the resources were taken by males in tribe A, where does female selection apply?

I think your theories are really interesting but there's a hole in this one. Tribe A also has parents. Not all reproduction happens through force. Female selection was probably happening in Tribe A.

The war scenario and arranged marriage mix things (which is one of the reasons what you say is interesting) but I don't think it's so black and white.

You created a single strawman scenario where female selection doesn't exist.

This doesn't invalidate literally hundreds of other possibilities where it could exist. Are you really serious about this right now? Do you not see flaws in the argument you constructed?
