If nowadays it’s accepted knowledge by everyone that sun exposure causes cancer then how did humans many years ago not all die without knowledge of this.

An even better question to ask is why would humans “evolve” to not be able to handle sun? ik melanin is a natural barrier but even blacks can get skin cancer and are recommended heavily to wear spf
 
cause u dont just get skin cancer for being in the sun for 40 minutes

How would pre civilization humans be limited to 40 minutes of sun exposure. I think it’s more likely they were spending the majority of their time in the sun.

clothing
and even further back hunter gatherers spent most their day doing nothing

less sun expsure = less vitamin d
so you'll have to evolve lighter skin to be more receptive to it

Might have died. They didn't have autopsy or post mortem stuff back so they might have believed it was a curse from gods or something

great point, i’m aware that lighter skin is meant to absorb sun and therefore vitamin d more effectively like caucasian cave dwellers or something. But my point is why would or how could a species constantly inundated with sun exposure, evolve to experience adverse effects like skin damage and cancer?, as even the darkest skin colors need to wear spf according to popularly held belief.

You do seem to already know more then the basics so i hope this will be able to fill your gaps

But then how could only some people die from exposure and not others, even if you say their genes were better adapted then why don’t modern humans have the same gene expression from those humans who could actually handle sun? Maybe you could say they were simply in the sun less but I think that’s too convenient an answer.

oh wait i re-read your post so forget the video that i send you. I'd say we are full of mistakes , because evolution is a gradua,l long and very diverging process and a perfect life form will never exist.

Not everyone that stays in the sun get skin cancer my friend

I was waiting for someone to mention this because I can’t really argue with this and if this isn’t a hoax by the cabal then it sounds very likely.

Ok I see, questions like these just arise to me because things like this (being exposed to the sun) are so fundamental and basic to everything on earth but despite this fact are things that seem to be so problematic to humans and I don’t understand how.

What specifically separates someone who gets skin cancer from the sun from someone who doesn’t with the same amount of exposure? Besides melanin ig.

Europe generally wasn’t sunny which is why Europeans evolved lighter hair and skin there’s exceptions though noticeable the Mediterranean and the Iberian peninsula in those regions the pale lords would often stay inside their castles to avoid the sun

Well the same thing that separates someone who gets lung cancer and someone who doesn't although they're smoking the same amount of cigarettes. Genetics + lottery.

Imagine 2 twins getting constant sunburn on purpose. Each time they get one, it's like a dice roll. The more they get sunburns, the higher the chances of developing cancer.

They did.
But they also died from many things before hitting 50.

because the human species did not evolve on this planet, we evolved on a different planet with a sun 2x the distance. adam and eve were sent here on a ship and the rest is history

doesn't make sense tbh. how do you grow food without sun
 
They died before skin cancer was a concern at 20 to 30 years old from other causes.

I remember the point where i'd have probably died from health issues at 23 years old if i was a caveman but because of medical technology it was nothing.

You need a shit-ton of sun exposure to actually increase your risk of cancer, most people these days don't get enough sun, because they work and spend most of their time indoors, this scaremongering about the dangers of sun is stupid and misguided...
 
you idiot.. sun expose just increases your chances of skin cancer via the UV radiation... its still super rare and something with such a low probability does not get filtered out by natural/ sexual selection.... its like saying auto accidents kill people.. so why havent all the people that drive died yet?

No you’re incorrect, skin cancer is very prevalent and is the most common type of cancer, cancer is actually the 2nd leading cause of death in the US behind heart disease, and your argument is erroneous as people nowadays take precautions like spf, and are warned to limit their exposure as much as possible and yet it’s still rampant, so just postulate how it would be thousands of years ago when nobody had this knowledge.

this. radiation and oxidation in general tissue degradation increase the chances of cells going haywire and getting cancerogenic traits when they reproduce due to their deteriorating dna.
 
The human body is not designed to live past 30/35. The normal male did not give a fuck about the daily risk of death. They where figthers and hunters.

They did develop cancer but to a much lesser extent. The reason behind this imo is due to 3 major things:

1. Genetic degeneration was not as prevalent back then as it is now. Not everyone could breed and most died young due to diseases or low genetic quality. Ever since the industrial revolution we've been a step ahead of nature in the sense than we can make the lives of people suffering from genetic disorders at the very least passable. In my opinion, this plays the biggest role in developing cancer. A good immune system will almost always prevent the development of cancerous cells before they go rampant and it is known that good a immune system is an indication of genetic superiority.

2. Lower quality food. Even if you don't eat out everyday and home cook 100% of your meals, they still won't be as healthy as they used to be 2000 or even 1000 years ago. Even if you home grow all your vegetables and animals for slaughter. Humans have been inbreeding plants for millennia and that has caused lower quality crops in favour of overall mass and flavour.

3. We live much longer and can cure or treat the majority of lethal diseases, making non-curable or untreatable diseases more deadly.
