It’s a biology simulation thing discussing how DNA uncoils from histones Of malls depending on how much affection they get from a parent (this is a very Vague layman’s description I know but this is a tumblr post not a science paper)
The long and short of it is that too little affection leaves the mammal anxious as hell as an adult and too much affection makes it too Calm as an adult and potentially Too lackadaisical when it comes to avoiding predators.
So to find the Just Right Amount you get to be a mama mouse and every click becomes a lick for the little baby and the program tells you if you’ve given too much or two little.
…that is actually really fucking cool, I did not know that was what it came from!
