I’m going to qualify this—all vertebrate eyes have a blind spot. Cephalopods also have eyes that are like vertebrates (this type of eye is called ‘camera eyes’), but their eye anatomy is such that no blind spot exists for them.

Piggybacking on your fact about the brain effectively editing what we visually perceive, we don’t see our nose (unless you made a concerted effort to look at it) because the brain ignores it.

A crow eating chicken and a human eating beef are actually really good parallels. Crows and chicken are 91 million years diverged while cows and humans 94 million years diverged.

I grew up in the 90s and went to public school, so I didn’t have this experience. What I did experience was using the shittiest scissors in the classroom, and having to share it with 3 other kids because there was exactly one left handed pair.

Also lots of criticism about my handwriting.
