Many plants can be propagated by grafting. Carefully break off a branch, rebury part of it in soil and voila, it sprouts roots, then shoots into a being of its own! Or is it? Had it stayed where it was, it would have been a part of the parent life form. However, now it is assumed to be distinct, a unique plant. Or could it just be called a transplant in space of the parent?
In essence so are we all, derivatives of our parents, transplanted in space and time. We grew from a cell each of our parents, differentiated into a whole. Not much different from the way organs develop from a single cell. Yet, the only difference is that organs remain inside the body while the progeny is expelled into a life form of its own.
We like to think of generations as unique and distinct. But are they? We are all but points on the line. You are but your parents on another plane.
The fractal of life.
