Skeptical about skeptics
You are just repeating what you posted earlier. You are suggesting the DNA argument should be thrown out of the window because of the existence of marginal cases. This would leave one less way of distinguishing a zygote from any other clump of cells in the mother - cancerous or otherwise.I didn't do that, I merely said that "unique DNA" gets problematic for the sole criterion for personhood, given identical twins and chimeras. I also said that being physically separate is problematic, too, given conjoined twins.
My final point is that there's nothing clear and easy out there..
The fact remains that a pregnant woman carries a life who's DNA is human and is not the same as its mother, father nor anybody else in the world. The fact that this life form can replicate itself withing the mother's womb doesn't nullify the entire DNA argument.
