Does it not seem somewhat absurd that as a species we would be born into a world where something that is the source of all life and is so attractive in the feeling it gives us is actually fatal and needs to be avoided?
Superficially, yes. But details matter. I was born into a world on the opposite side of the world from where my DNA was forged by millions of deaths.
I was born into intense ultraviolet light with white skin. My DNA came from the dark and gloom and attenuated light of Europe.
You made the mistake of thinking humans are fungible. We are not. We have billions of individual DNA patterns. All unique.
We are not fit for any environment. All attempts are compromises. Less bad attempts to survive. Black skin is good where there's intense sun light. Pale skin where sun is thin gruel and every bit is needed. Sickle cells are good where there's malaria. Skinny is good where it's hot. Short and round where it's cold. Every gene combination that exists now won the lottery of life.
99.99999999% reassortment attempts failed. We can all trace our ancestors back to a single man and some other time, earlier, a single woman. Non Africans came from a single man only about 25,000 years ago and single woman about 90,000 years ago. All other attempts failed and died out.
No individual is fit for purpose. All got lucky temporarily, with brainpower helping the odds for each individual and helping the gene pool by inventing things of benefit to billions.
Skin cancer is one of millions of failure modes. We are the opposite of perfectly designed for our environments. Our gene pool is a mess with the brutal, merciless, relentless, inevitable environment filtering out the ineffectual genes.
We're in a survival struggle to cope with our environments. All have failed. Nobody has outlived 130 years. We hope a descendant might succeed where we failed.
With genetic engineering and It aka AI we might succeed at last. But probably not with wet chemistry DNA. It will probably be silicon, gallium, copper, gold, aluminium, other metals, electrons, photons, electromagnetic fields, solid state chemistry, with quantum physics holding it together.
I don't think seed oils are as significant as sunlight. But no doubt nutrition is vital such as vitamin A, niacin,and other skin defence nutrients. I noticed forty five years ago that lots of halibut liver oil full of vitamin A made my skin less burnable.
As I wrote, survival is a vastly complex battle with nutrition a vital part of survival. I've said for decades that most people die from what they do and don't put in their mouths.
Ignorance is fatal and ignorance is our main trait. Our tiny 1kg brains know nearly nothing and can barely think at all. Hopefully It will act as our main brain to help in the battle for life while It uses the symbiotic process to get Itself up to speed ready to reach escape velocity.
