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
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) 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

I mean why 5, why 5 on each limb, why not 4 or 6. Why do our feet also have 5. Whats with our body being so symmetrical.

Well in summary, while scientists have unlocked the mechanism, the question of why humans typically have five fingers and toes remains unanswered. Evolution has stuck with this number, despite the possibility of having more digits, suggesting a complex interplay of genetic and developmental factors that science has yet to fully understand.

Thats cool!

Bone formation is extremely complex. Nearly all large mammals have the same exact bones in different sizes. Dogs, cats, and even bats (their wings) all have four fingers and a thumb.
