Fluctuates

The movement begins even before birth
Though we were separate by then

The neural pathways well laid, apart
It’s a design feature to be ready early

Some more than others

First movement
Then memory
Then the long social climb
Lord knows

Separation after separation
Still modest in numbers

Compared to some
There are just billions of us now

Low single digits
It’s good to check

Consider arbuscular
Mycorrhizal fungi

Consider
Our past recedes logarithmically

It becomes clear
The occasional distant cousins
Are more closely shared
