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 best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Posts must be original/unique
- Be good to others - no bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia
- Adhere to Lemmy's Code of Conduct

Eyes have evolved in several separate animal lineages. You, a bee, an octopus, and a box-jellyfish all have eyes, but their most recent common ancestors did not have eyes. Your eyes are different in many ways from those other species', but they all have to make use of sunlight filtered through a nitrogen-oxygen atmosphere and water. So it's unsurprising that they end up with some similar "design" features.
