Why are square shapes rare in nature? I know some rocks/minerals can be square but mostly everything is curved , is there a biological reason why it’s hard for natural objects to have straight lines?

In biology, a big thing is the ratio of surface area to volume. Like a water balloon, the goal is the most water with the least balloon, because making the balloon part is hard work.
A sphere is how you store the most amount of stuff with the least amount of packaging.
So for small things like cells, it’s more efficient to be round.
The downside is that when a cell gets too big, it can’t bring enough supplies through the cell membrane to sustain itself, so it divides into two.
On a larger scale, if there is no biological advantage to having straight lines or corners, they won’t exist because living bodies are lazy.
