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:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. 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
  4. Posts must be original/unique
  5. 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.

It's equally possible that there was more than one or even a day where only people were born and no one died.

There was a low point where only about 2,000 humans were estimated to be alive. Certainly you couldn't have had someone dying everyday then

Here we stumble again on the flawed definition of a species. It’s not black and white. Biology is a fuzzy mess with no clear borders, so the fuzzy terms should be treated accordingly.

People love clear boundaries, but biology doesn’t work that way. Everything in biology is incredibly complex, so any rule of thumb comes with huge caveats. Fuzzy concepts like "species" or even "life" are useful—as long as you avoid the grey areas.

The moment you start exploring edge cases, all bets are off, and the warranty on all neat definitions expires. Nothing works neatly with edge cases, so those who wander into the grey area are on their own.
