As I mentioned in an earlier post, there is no single point, much like with the Sorites paradox. It's acceptable when it's a zygote or blastocyst or embryo, not acceptable when it's due to be delivered in a day, and in between there's a large grey and ambiguous area as it develops more and more into a human like us.
There is much more to an organism than its genetic makeup. There are very real, significant, and obvious biological differences between myself and a zygote. Your decision to only consider an organism's genetic makeup is not less arbitrary than my decision to also consider these other important aspects of an organism's being. But I do think that your claim that only an organism's genetic makeup has moral relevance is an absurd one.
Every single one of you were zygotes. Luckily no one treated you with such disregard. — NOS4A2
The vagueness of the terms used to describe it and the arbitrariness of the acceptable time to kill indicate this. This is because the position lends itself to incoherence. — NOS4A2
Well, ethics is about what we do. And I'm off to an art exhibit and lunch with friends.
Not something that can be done with a zygote.

We wouldn't know, or care. That's not a moral consideration.
None of this is the case, and the quote you responded to points each out. There is no incoherence. There's just potentially uncomfortable bullet biting.
THe 'vagueness' of the terms doesn't exist. The facts are vague. The terms refer to them. This is no point at which a zygote 'becomes a person'. It does not exist. It occurs somewhere in the grey area and any position has to choose an arbitrary point here if that's what the view is based on.
(though, its very, very much worth noting that 'arbitrary' is not apt here. There are reasons which very much restrict what's acceptable on most views except absolutists ones (i.e killing an infant is also fine, or there is no form of contraception which is acceptable).
I wasn’t aware that one needed to know and care if he was being treated morally. — NOS4A2
What facts are vague? I ask because we actually know a lot about zygotes. — NOS4A2
Now you are. Morality is strictly to do with how we treat one another. A Zygote is not a 'one another'. This is probably the only intuition of Banno's I think needs no defense. This just, as noted, leads to some hefty bullet-biting.
At what point the zygote becomes a 'person', or variably 'baby', 'a human' etc... etc... These are the 'facts' on which most people's positions rely(i have excluded those absolutist positions that are doctrinaire rather than reasoned) and they aren't stable or lets say 'complete' enough to objectively inform us of anything within that grey area as to why we would place the flag 'there'. Yes, we know a lot about zygotes and their development, but which way-point would you choose? It sounds like for you it's conception. Others might be implantation, heartbeat, viability, pain reception among others. But none of these are hard-and-fast in terms of telling us when a 'person' comes into being (or, when that might be morally relevant). I can only really understand taking conception to be the salient point if one is to be, lets say, overly cautious, because of the above indeterminacies. If you're not copping to that, I'm unsure how to make sense of it. But this doesn't seem to me a moral question, anyway. It's similar to saying "well, I can't figure out the precise moral facts, so I'll give it a wide berth". I can't see a real problem in that, other than tryig to make others assent (which you're not doing, so that's fine).
Odd, this turn of phrase. Lucky for me? No. Since I am here it is inevitable that some zygote survived. No luck involved, just bland necessity. Any other zygote would not have resulted in me, but someone else. Lucky for the Zygote? It should have bought a lottery ticket? Happenstance, not luck.Luckily no one treated you with such disregard. — NOS4A2
The biological difference between you as a zygote and you as an adult was that you were in a different stage of your development. — NOS4A2
I believe members of the species homo sapiens have moral relevance. — NOS4A2
You never once deviated from being this particular human, you still occupy the same location in space and time, no matter what nouns you use to identify the state of your development. — NOS4A2
having actually developed the appropriate cognitive capabilities is required — Michael
