'Temperature and sex ratios at birth', a new study led by researchers at the Department of Sociology at the University of Oxford and published in Proceedings of the National Academy of Sciences (PNAS), provides new evidence that higher temperatures can influence the sex ratio at birth, with important implications for population health and gender balance in a warming world.

    The results show that temperatures above 20°C are consistently associated with fewer male births in both regions – but through different mechanisms.

    In sub-Saharan Africa, exposure to high temperatures during the first trimester of pregnancy is linked to a decline in male births.

      Wait a sec, let me check my notes… because… ah, yeah, because humanity apparently goes extinct when all males die off. Oh. That’s a bummer.

        Probably ok if only 30% of population are male. Maybe even 10% with genetic database. Society and culture will take hit but realistically sperm is not a hard to come by resources. Lol just imagine mail ordering that stuff.

        There’s probably is a path to female only reproduction using artificial means. I suppose it would be possible with men too, if we could synthetically gestate a child, but it’s probably easier in women since they possess the evolved ability to gestate. Parthenogenesis has occurred in other organisms, possible perhaps for humans too, with help.

          Oh, okay. But wait a second, there’s something on the back as well. So…hmm… apparently there are parents who don’t like it very much when their unborn baby fucking dies.

          Huh.

          But yeah, when what you want is everyone to be miserable and fucking die, then yes, you’re right that in that particular case sex doesn’t matter.

          But remember that’s just you and not everyone is nuts.

          The rest of the humans will follow shortly. If that still sounds good, change starts at home.

          Thought experiment:

           You - "Why is race important again?"

 Because if we got rid of all black people we'd lose perspective and culture.

 You - "Doesn't sound so bad to me"

          Conclusion: you are a bigot

      biology is interesting. and learning more about it helps us understand ourselves better and improve medicine…

      i don’t think that research aims to control if someone will have a boy or a girl.

      like studying the genetics that affect melanin has nothing to do with racial discrimination.

          yes it’s a bad thing

          Edit, it’s much later. honest to gawd. I love men. you do understand how hurtful this comment youre making is?

          just like ‘woman bad’ is a shit take, so is yours.

          like why. I come from, a long line of shitty men (and women!!). I hope my son is the first man in his living bloodline to actually feel at peace with himself so he doesnt cause distruction, Im near certain im the first for the women in the family. I still love men, because ive also met so many who are just so genuinely kind, cool, empathetic and giving. These traits can be found in any human, from any background.

          I dont generally like to call names, but youre fucking stupid for adding to the culture war. I just hope anyone who sees your shit take also see this. Im a woman, and this person making jokes about the world being better off with out men is the dumbest fucking shit. no one chooses how they are born. dont be such a daft cunt.
