Around this time we know there was a rise in human migration and settlement across Europe in particular. A human Y-chromosone haplogroup associated with the Near East shows up in Italy, and Western Hunter Gatherers start to move across Europe replacing the Magdalenian cultures.

I wonder if this event prompted people to think about the World around them differently in any way.

Im more convinced we are heading that way every year. Certainly not anytime soon, but 100, 200, 1000 years from now? Seems plausible to me. Most people don't even know how their house electricity system is setup or works, or how their plumbing system works despite being incredibly simple, not to mention more advanced technologies. We are surrounded by internal combustion engines and yet less and less people actually…

Who cares what most people know about plumbing and electrical wiring? It's not most people's job to fix it when it breaks.

What a strange attitude. It certainly is not anyone else's job to maintain the home I own and live in. That is my job. If something breaks, I don't get to tell someone else that they have not done their job. I am responsible for fixing it. Yes, I can delegate a specific fix to a professional electrician or plumber, but that is a project-by-project choice.

If people want to approach life by hiring out every little thing, they can certainly do so, but those choices do not make my home maintenance someone else's job.

Holy shit, is this the squatting man? (strangely similar stick figure cave drawings dating to the same timeframe all over the world, and reproduced apparently with high energy plasma experiment).

Baseless wild speculation time: I don't think the timing quite matches up, but the Neolithic Y-chromosome bottleneck is a little close to this.

What if radiation from the sun actually sterilized something like 90% of neolithic men? Is that possible?

This creates a selection pressure for men whose sperm just happens to be resistent to the sun's radiation to get with as many women as possible. So any groups that don't practice patriarchal polygyny are at a sudden and catastrophic disadvantage for not utilizing their men who are still fertile and get outcompeted in a generation.

Thousands of years later we're still unwinding the social ramifications of this.

Flonase (fluticasone) has been a life changer. I have taken for granted how valuable breathing is in terms of speech, let alone sleep and general fatigue.

Moving to the coast made me feel like I finally woke up, after growing up perpetually stuffy and sniffly. Turns out I'm not a mouth breather after all!

Yep - moving away from the coast basically did the opposite for me. :(

Most other primate species, indeed most other mammalian species, polygyny is the norm

Sure, but assuming humans are just "naturally" polygynous doesn't explain the actual observed range of human behavior or the Y-chromasome bottleneck I just mentioned.

There won't be any effect. Solar flares do NOT affect the devices on the ground. All the fast-moving charged particles are completely absorbed in the upper atmosphere. And to give you some perspective, the most energetic flares can produce 10^-3 W/m^2 flux at the Earth's orbit. The flares do affect the geomagnetic field. And a changing magnetic field induces current, but it becomes non-negligible only for very long c…

They won't affect your phone or laptop, but transformers along the longer ranges of the grid are unprotected. An X-class flare won't do anything. But in the size of the article? Localised temporary blackouts would be entirely unsurprising.

> They won't affect your phone or laptop, but transformers along the longer ranges of the grid are unprotected.

They actually are. Protection against lightning strikes and atmospheric electricity is a part of the design for the high-voltage lines.

CMEs might cause enough additional load on the lines to cause them to trip if they are close to failure already, and this is well-recognized and can be mitigated by load-shedding early.

Just moving away from what your body decided to be allergic to when you were a kid with a bored immune system seems to help a lot, I moved from the Gulf Coast to the West Coast and my allergies receded a lot. I eventually moved back to where I grew up and they didn't really return except on days when the whole city's collective nose is running because all the trees are having an orgy up in there.

This would not have been kind to any RF/EMF systems, be they GEO, LEO or terrestrial. We'd have been walking around marvelling at st elmo's fire coming off any point-contact junction between metal or exposed metal structure, with the most fantastic skies at night. On the other hand, would allergy sufferers be marvelling at the removal of all the dust and pollen? This would be like the outdoors becoming a giant anti-s…

Aren’t smaller microprocessor die sizes more vulnerable to this? Should we be building integrated circuits with larger feature sizes now that we have power and performance figured out?
