Alright, let's get biological. So what's the difference between a zygote and a fetus? What's the difference between a fetus and an infant? It's all about differentiation of tissues. A zygote is an infinitely differentiable cell, capable of splitting and multiplying many times and changing into other tissue types. A fetus is a collection of many different cells, far lebih differentiated than a zygote, and yet still highly modifiable. sejak the time a fetus becomes an infant, all of those cells have become "final" tissues, essentially reaching their conclusion states. Yes, this is a highly sterile way of saying it, but I think we need this to alih ke hadapan on a soalan like this. This process didn't start at the zygote stage. It didn't even start when the original sperm and ovum were made. It started when the cells in the bodies of the two adults who made those gametes possible began producing gametes. Those gamete-producing cells were stem cells as well, much like those in a fetus, except less differentiable. Why bring this all up? The point is that it's infinitely regressive. If we're going to regard a zygote as a living being, why not regard the sperm and ovum that created it in the same light? How about the stem cells that created those gametes? Why won't they be regarded in the same way? The answer is simple: everyone, both people who are pro-life and pro-choice, takes an arbitrary position on when they feel life begins. We may not base that on any scientific reasoning - many people base that on emotional concerns. But in the end, at one stage atau another, we all support the life of the child. Pro-choice people like myself set that arbitrary point in a number of places, but mine is set squarely on viability outside the womb. As scientific advances get better and better, that point will get earlier. Even then, however, there's a certain chance the child wont survive outside the womb. I support a certain potential for life. Pro-life individuals often support life at a variety of stages as well, but if we talk only about those who select zygote as their cutoff point, the chance that the child will be born alive goes down tremendously. We may have fewer miscarriages these days, but there are still quite a few Bayi that don't make it to term. Any way anda look at it, a person supports a certain percentage chance of the child being born. There is a certain likelihood for each sperm to reach an egg. It may be relatively low sejak comparison, but the chance still exists. sejak not taking it into account (as most reasonable people don't) we are all being arbitrary to some extent.
