Quite the thread.
I've always wondered where one might be able to draw the absolute line as to what is human and what is not. It is true that the very smallest human cells contain all the DNA to become an adult human.
So, in that case, any "seed spilled on the ground", any menstruation allowed to progress unfullfilled, any li'l swimmers out of of 50,000 that don't arrive first, all constitute human death of sorts.
I've read that we evolved from single cells that existed eons ago in the oceans upon the earth. And to this day we even pass through all these stages as we "evolve" from the single cell(s) all of us began from. Most common life on earth shares significant DNA.
We initially reside in a salty sea, about the same as earthy saltyness, as we grow in the fluid of the womb. As the growth becomes vertebrate, the little embryo looks pretty much like a fish then a lizard for a while, including apparent gills. Then it begans to look like a chicken embryo and finally a more advanced mammal. Pretty soon looks like a primate. Shortly before birth, human.
Some of us here, of course, are derived from saltier environments than others.
