A very simple divide, split, repeat pattern can result in a fractal. Trees and such. Corals. Fractals are simple types of shapes to form iteratively, and to code for as a growth pattern.

Blood vessels in the lungs optimize for oxygenation, so you will have fractal branching. Evolutionarily speaking, being fractal-shaped or having fractalized organs is often more fit than being non-fractal or having non-fractal organs.

Mostly "un-fractal" creatures - like humans - are much more difficult, anatomically, than for example, basket stars, whose shape can probably be expressed as iterations of a quite simple mathematical expression. 

For shorelines, river systems and erosion patterns you have scale-invariant physics as an explanation.

When it comes to primes, I must admit I am not very read-up, and I have never understood the fascination with them or why it is supposed to be strange that some numbers aren't very divisible.

I imagine some numbers having that property is just an artifact of there being a linear set of numbers?

Wouldn't it be weirder if all numbers were non-prime? Imagine an entire set of infinity numbers and they could all be divided. That would also be weird, imho.

Maybe I just don't understand what the deal is with primes. Maybe that's on me.
