No, fuckstain. A skin cell is not A human life. Why is it that you leftists blather about your worship of "science", and yet are so abysmally ignorant of any scientific facts?
Furthermore, a "first trimester" - I presume you mean an unborn child in the first trimester of growth - does not "look like a little human towards the end". He looks like a human all the way through, because THAT'S WHAT HUMANS LOOK LIKE AT THAT AGE. What you mean is that he looks more like an ADULT human towards the end. And an unborn child in the first trimester is chockful of humanity. He's fully human; what ELSE would he be? He was produced by two humans, and like produces like. They don't create a giraffe embryo that suddenly morphs into a human at birth.
As for functional brains, it's clear from this mess of unscientific garbage that YOU have no business touting brain function as any sort of requirement for life or value. Likewise for consciousness and thought. I'm just saying . . .
Nowhere in the definition of "human being" is there "looking like an adult and having an adult brain". Ditto the definition of life.
As always the dumb ass joke that I have no brain. Twice already in this thread. By stringing together words, I prove that I am capable of thought and awareness. A first trimester fetus is not capable of either.
All of being a human being, what distinguishes us from animals, is our brain function. Now, some birth defects cause less well developed brains, but once the brain is capable of thought and awareness, it is a human being. Even the most severely handicapped human brains are capable of creating thoughts and emotions lower animals are not capable of. A first trimester fetus in contrast has no mental ability whatsoever, and hence none of the fundamental brain function necessary to be considered a human being.
That is svience. You in contrast engage in nothing but emotionally charged gobbly gook and nonsense that completely disregards the scientific fact that humanity is differentiated from non humanity by our brains and hence your argument stands null and void.
It's not a joke, Sparky. I'm completely serious that my first-grader could present a better-reasoned, more scientific argument than you are. I'm also completely serious, behind the dripping sarcasm, that a system of valuing human beings only if they meet trumped-up, self-serving, arbitrary criteria is a slippery slope you do NOT want to start down.
And frankly, given the utter lack of relation your words have to fact, I'd be inclined to challenge the notion that they prove any capability of thought. Parrots can be taught to form words, too.
But leaving that aside for the moment, you keep prattling on about "fetuses aren't human because they can't act like adults". Adulthood is not a requirement for membership in a species, nor is it a requirement for being alive. Newborn infants can't speak or cogitate, either. You keep pulling these goalposts out of your butt and being completely oblivious to how they apply to many more phases of human existence than just fetal development.
There are many things that distinguish us from OTHER animals aside from our brain function (and other animals possess brains as well, of varying levels of cognitive power). Your belief that humanity magically appears upon acquisition of a specific level of IQ (although it can, apparently, generously be conveyed by society upon those who don't achieve that level due to handicaps, perhaps by use of a magic wand) is not science; it's just a mess of half-formed excuses to justify your selfishness.
I, on the other hand, have not said anything that is emotional and unscientific. Everything I have said is verifiable from scientific sources, and never once employs the word "belief". Humanity IS differentiated from non-humanity, but none of that has anything to do with differentiating stages of development, and it is not determined by our having brains. Humanity does not arise from non-humanity, and hence your "argument" is no argument at all, let alone nullifying and voiding anything.
There is only one goalpost, it does not move, and it is not arbitrary. To be a human being, one must be capable of thought, awareness, feeling, mental capacity of some kind. I think, therefore I am.
There is no IQ threshold, there is no slippery slope. To be a human being, it must be human life, and it must be capable of the brain function necessary for thought, awareness, i.e. Descartes definition of "I am". i.e. being.
See, genius. Human being has two parts.
1) human
Yes, you all have that covered
2) being
This is the crucial part that you and you ilk seem incapable of understanding.
So, no, we're not going to be executing downs syndrome children, so relax, "sparky".
Now ... on to the science. The brain is incapable of thought until the pieces are together. It needs a thalamo-cortical complex according to this article, which develops in week 24
When Does Consciousness Arise in Human Babies?
However, I'm willing to err more on the side of caution, and require something less sophisticated than proven "consciousness". Even being more conservative, the first trimester is not when reflex actions demonstrating higher cranial function begin. That would be second trimester
What can science add to the abortion debate?
There is science. Logical and dispassionate, whereas you are only capable of arguing emotionally. This renders your argument null and void, nothing I've said does.
I honestly don't care if you have one arbitrarily made up goalpost or twenty. It's still false and unscientific.
See, fool, you're still arguing philosophy in place of science. "But the term is human BEING. BEING!" Thanks for the attempt at semantics, but no.
In scientific terms (not literary, philosophical, or infanticidal), the word "being" is a synonym for "organism", just as the word "human" is a synonym for "hominid". Even Merriam-Webster contains this particular, simple, scientific definition. Without the rhetorical hearts and flowers, a human being is a living organism of the human species. Biology is not interested in how you feel about that.
I like that "now . . . on to the science". At least you're admitting that the bullshit before that wasn't scientific.
Unfortunately, everything after that was irrelevant, because it assumed that your arbitrary goalpost was correct and going to be accepted as the parameter for debate. Since the debate happens to be how incorrect your goalpost is, that's not going to work.
Furthermore, citing anonymous opinion blogs as "scientific evidence"? You're just making my case for me.
On the other hand, we can go to a PhD from Princeton, and her footnote citations from embryology textbooks and publications used by universities to train actual medical scientists. I dunno, maybe it's just me, but I find that more reliable, somehow.
When Do Human Beings Begin?
Or we can go with the Journal of Medical Ethics and History of Medicine, from the National Institutes of Health.
Fetus as Human Being: Where is the Cut-off Point?
I can go on and cite you the actual embryology textbooks and any number of medical, biological, and embryological journals, if you insist.
