Can science explain why the ratio of females to males is approximately 1:1, despite the fact that only 1/3 of males end up reproducing?

>> No.11049474

Citation needed, but the common line of argument is
https://en.wikipedia.org/wiki/Sex_ratio#Fisher's_principle
and I'm sure there's a million extensions of it since the 30's

Male ratio is much bigger than female ratio. It's not 1:1 more like 4:1. Depends if country is after or before war.

Whats actually crazy is that the ratio skews towards males in a pretty significant way after a large conflict kills a disproportionate number of men and then just returns to normal.

Continuing this thought, men are the disposable gender. Women are required to be alive for children to be born whereas a male doesnt need to stay alive for his female counterpart to give birth.

Yes I can.

From the book the 'selfish gene' (a absolute must read btw):..

Say there was an even more imbalanced situation that human incels.

Take elephant seals. In an elephant seal colony only a few % of the males actually reproduce. The rest are basically celibate or die in fights with the chads that reproduce.

You might ask in that situation why don't elephant seals stop having so many males? Seems like a waste right?

Let's consider what happens if they do: If elephant seals could 'decide' or 'evolve' to produce 99% females and 1% males... Then we could think about a population in which there are 99% females and 1% males. Now as a INDIVIDUAL elephant seal.. it pays you a SHITLOAD to have a male, because if you have a male child your genes spread like WILDFIRE... whereas if you have a female child you can only have the normal amount of offspring.

So.. there is a massive evolutionary pressure to create MALES... this will revert the balance back to 50%. Infact in most species it's self balancing exactly at 50% because of how reproduction works. 50% genes from mom 50% genes from data.

Any movement away from the 50% would genetically PAY the smaller ratio to increase itself.. until it self balances.

Yep. Nature doesn't give 2 shits about incels, no matter how many schools you shoot up. The media might care but, ESS ratios and math don't care ;P

Because women don't only birth girls. How is this a question?

>> No.11051310

>>11051270
To follow up on this...

What it means for humans over a longer term:

The 50% sex ratio is fixed genetically, over the hundreds of MILLIONS of years it takes for vertebrate sex ratio genes to fix themselves... It's been determined that if there was a random mutation in which a single organism had a 49% chance of males and a 51% of females.. that organism's genes would actually do WORSE off than a 50/50 ratio.

Why not have a 2:1 women to men ratio?
Why 1:1?

>> No.11053446

>>11053440
men die too frequently from disease and warfare, women dont harvest enough nutritious protein laden foods to keep the tribe alive by themselves and the hormonal and behavioral profile of an aggressive animal like a human male is not compatible with the behaviors required to raise human children. we would have had to shift the entirety of our evolutionary trajectory towards something like elephant clans or lion prides to get away with skewed female:male ratios and we have neither the body size nor the killing prowess to do this (though there was no choice in the matter). the acceleration of weapons development due to intertribal conflict and the benefits of dividing labor between the sexes allowed our technology to advance to the point that crop domestication war more efficient than hunting and gathering increasing our relative fitness in an environment that still favored megafauna over us.

This. The whole self balancing ratio thing is misnomer, because the sex outcome is a random choice since multiceller orgasms became sex differataned, it happens before the expression of evolutionary pressures.
