A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- NEW RULE as of 5 Nov 2024, trying it out
- Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct-----

Incest doesn't inherently cause genetic disorders, it just increases your chance of being born with recessive genetic disorders. Most of those disorders are mutations, and if the Garden of Eden is so perfect there probably aren't genetic disorders to start out with, meaning incest is fine from a genetic perspective. All the genetic disorders would be mutations later down the line. Maybe they're punishment for the original sin or something, to fit it into the themes of the story.
That's a fantastic retroactive nonsensical explanation for Adam and Eve. Bravo.
Nah genetic disorders aren't mutations, they're incorrect copies of original traits. I'm not a geneticist so don't quote me on this, but the reason incest causes problems has nothing to do with mutations as they rarely happen and everything to do with not having enough variation in your own genetics to cover when there's "data loss". Again, I'm not a scientist.
Incorrect copies are mutations.
Correct copies are also mutations, for what it's worth.
