What's the evolutionary advantage of very long hair on human heads?
15h 49m ago in nostupidquestionsThere are two different things coming into play here.
First of all, hair length evolved before long hair did.
Modern humans originally evolved tightly curled hair. Basically like we still see in many African populations. It's thought that this was an adaptation to protect against the heat of the sun. Basically like an insulated sun hat. The longer this curly hair grew, the more protection our natural hat provided.
As homo-sapiens populations moved further North, this protection was no longer needed - in fact there was the opposite problem, it was cold and rainy.
Greasy straight hair offers an advantage over curly hair in this kind of environment. It acts like a waterproof blanket, preventing the skin beneath getting wet, and it dries more quickly. Heat is lost through wet skin significantly faster than dry skin, and in situations where energy sources might be hard to come by in winter months, this can be a disadvantage.
We already had hair length sorted, so it was simply a matter of reacquiring the straight hair shape.
Europeans got a leg-up in this regard - Neanderthals appear to have had straight hair, and interbreeding definitely occurred. At this point it's worth remembering that by the time anatomically modern humans evolved in Africa, earlier hominids were already living all over Africa, Europe and Asia. Neanderthals were very similar to modern humans and shared an extremely close common ancestor.
And this is how, and why, some homo sapiens populations have long straight hair.
I won't touch on the points covered by the other replies because they've explained it perfectly. I think you're confused about the divorce thing, though.
It was King Henry VIII who founded the church of England to allow him to get a divorce. But his version of the church was essentially identical to Catholicism but with the king instead of the pope.
His great great grandson, King James VI / I actually cared about religion and reforming the church. He supported the idea that everyone should be able to actually understand the scripture, instead of just the elites and clergy. That's why he sponsored the King James Bible. He was also very anti-Catholic and, as a direct result, was targeted in the Gunpowder Plot.

I'll just quietly crumble into dust now.

Making the bed
9d 13h ago in comicstripsI make my bed purely because my wife likes it that way. I'm not bothered either way, but I do it because it's important to her.
She wakes up before I do and goes to bed before I do. I make the bed nice and tidy when I eventually wake up so she has a nice neat bed to climb into at night.
Do Reform suspensions suggest political vetting system isn't working?
9d 13h ago in uk_politics@feddit.uk from www.bbc.co.ukWhat vetting system?
From what we've seen, the system seems to be "yeah, I'll stand", "good man, you've got the job".

9d 16h ago in nostupidquestionsPutting all patriotism aside, I don't think there's any reality in which the US uses its potential to make the world a better place.
The big difference nowadays is that it's become patently clear that the US government isn't even trying to make the US a better place.
Purpose of the shredded flags hanging half mast in London?
13d 8h ago in uk_politics@feddit.uk from sh.itjust.worksThese are just the normal England flags tied to lampposts by wannabe Blackshirts.
They appear half mast literally because that's as tall as their ladders are.
They are tattered because although their "patriotism" extends to marking territory, it doesn't include maintenance or upkeep.
