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.

The current species of sharks evolved around 200 million years ago, so yeah the species of sharks today have everything in common with the species of sharks 100 million years ago. Sharks are famously also remarkably stable in their evolution. They do evolve and branch out with specializations, but physically the basic shark form has been the same for a very long time. The sharks that were around 400 million years ago when trees first evolved would have been very similar to the sharks we have today.

Not so sure about that, considering one of the shark fossils discovered had teeth like tombstones, and another had a weird sawblade for a lower jaw.

Those were just rare special edition sharks. The rest of the sharks were just normal ones.
