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. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

There are a bunch of characteristics that, while fairly arbitrary, can't be changed once they are locked in. The mappings from RNA to proteins are a good example. Changing it is instantly lethal to the cell involved. Others include the chirality of amino acids, and the choice of bases for DNA.
If we look at the entire tree of life, we see no deviations in these deep characteristics. This implies that they were fixed before we all split. There might have been alternative variations in the past, but none have survived to the modern day (that we have identified).
This goes double of eucaryotes (basically everything other than bacteria). The design is so unique that convergent evolution is highly unlikely to stumble into the exact same layout from 2 sources.
Ah, alright that's a fair point. Once one of those splits happened then that single life form would have become the common ancestor for all other life. I'm satisfied with that explanation.
