To explore your argument a little further, would a detached human finger, by itself, be a human being? The DNA contained would identify it as so. What about human cancer cells grown in media?
Yes, they would be all human beings. That they are is a biological truism. And that is why Woody Allen can threaten to kill the dictator (his ear) while trying to escape, in his Sleeper movie.
But, of course, morality cannot be applied to human biology alone without being circular. So, we need something that is independent from mere DNA, while acting on something more than that.
what is that more than that?
if you need to decide between 1000 human cells in a petri dish, vs, 10 kids at school waiting for their parents outside, how would you decide? No matter, or would you give priority to one of them groups?
