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

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

The unpleasantness of mosquito bites is not something useful for mosquitoes, but it is useful for the ones who suffer it (lemmy.world)

The way our bodies react to mosquito saliva motivates us to avoid being bitten. Which must have had evolutionary benefits, keeping us away from diseases.

I.e. all those people that didn't mind them and never got itchy from mosquito bites appear to have died out. And mosquitoes really wish that wasn't true.

Biting insects kill more people than any other animal group by miles, the reaction response is more or less the same in every mammal. Evolution doesn't evolve to anything, that's selective pressure.

This behavior predates humans as we know ourselves today.

I take issue with this obvious selection bias. Of course this is true when you're pre-selecting for only the insects that bite people. If you were to preselect only those sharks that have bitten people, so-called biting sharks, I think the shark-bitten people have a higher average early mortality than the insect-bitten people. /s
