    Well, to some extent, I pulled it out of my ass. To a different extent, my ass is particularly qualified: I'm on my way to a PhD in archaeology. I believe there is a geologic table in Merriam Webster that has dates of these periods, but I"m not positive. Regardless, I know when the boundary between the Middle and Upper Paleolithic are, and I know what the currently accepted (though, as always, subject to revision) theory as to the evolution of homo sapiens sapiens is.

    By "not 'people' as they are today" I mean that, prior to the Upper Paleolithic, there was very little differentiating our ancestral hominids from other (modern or ancient) nonhuman primates. They could make tools more specified, but still were barely capable of more than a modern chimp using an anvil to crack a nut or a twig to "fish" for termites. There has been no indication of any ability to think symbolically.

    Toward the end of the Middle Paleolithic (about 35,000 to 40,000 years ago) we begin to see three very important things: 1. displacement of materials over very large distances, 2. intentional human burials, and 3. evidence of collective planning and coordinating, especially in regards to hunting meat. Materials being displaced over large areas that share no boundaries indicates a capacity for symbolic displacement, or the first necessity for language. Perhaps some sort of protolanguage arose during this time. Intentional burials are the first evidence we have for any sort of symbolic act. These things all indicate the very beginnings of symbolic thought. You must admit that, since we're talking about the very beginnings of symbolic thought (and that we, currently, are capable of language and symbolic thought far beyond this level) it's only appropriate to remind everyone here that these are not "people" we're talking about as we are people today.

    So, with the capacity for symbolic thought emerging 40,000 to 35,000 years ago, the appearance of something so complex as a representation of a human face at 30,000 years ago would tell us a lot. For quite a few thousand years after that point, all we currently have are uniform-looking fertility figures and stick-figures hunting elaborate animals painted on walls (yes, the limits of what we've found in the archaeological record.) Regardless, somewhere on the border between Middle and Upper Paleolithic (and where do you think these borders come from?) something changed dramatically in hominids' perceptions of the world. They gained capacity for symbolic thought-- they perhaps became capable of drawing a face and recognizing a drawing. Additionally, it is just at this time (beginning of the Upper Paleolithic) that Neanderthals go extinct, and that our own forerunners are left to dominate the hominid line. (Before this extinction, technology and art and symbolic things like burials were associated with neanderthals as well-- not just our own ancestors.)

    What I got out of the article is that caves with paintings of animals in them date back nearly as far as the end of the Middle Paleolithic and beginning of the Upper. Given the faces on the floor of one of these caves, it is possible that there are others in the other caves mentioned-- the ones that date back 30,000 years. Given that possibility, we could learn quite a lot about the development of early hominids.

    It's not about when we come across it. It's about when they were capable of it. That early, people were not "people" as they are today. When did they have the physiological capability and the tools to draw? When did they have a sense of the symbolic and representational enough to draw people? What are the implications of drawing people at all, when previously the cave paintings weren't thought to contain any detailed pictures of people, merely of animals? Further, were the people they were drawing real (ie, a friend or family member or...) and if not, what are the implications of drawing imaginary people?

    It seems that capacity for symbolic representation began in the Upper Paleolithic. That's before 15,000 years ago, but just around 30,000 years ago (the dates in the article.) The earlier and more complex the art that we find, the more we learn about long-gone cognitive processes that preceeded our own.

    I totally disagree. I have had friends who have had abortions, and yes, it's traumatic. Carrying a child bourne of rape? We're talking an entirely different level of traumatic here. A rape is about the worst thing a person can endure. Way worse, alone, than the guilt and emotional trauma caused by an abortion. With an abortion on top of that, it's unthinkable-- with a child on top of that, it's unlivable. Most girls would rather kill themselves than bring a rape baby to term. Most girls I know who've been raped, that is. And I know quite a few. 1 in 5 women, after all, have been there.

    I understand your view of the unborn as a full-fledged person. Do you believe that an abortion is justified in the cases where the mother would be in mortal danger from the pregnancy? Because I believe that this is a similar case.

    I also think that this:

    If you kill the kid to rid yourself of memory of his father, then you'd be just as justified in killing your (grown) children to rid yourself of all memories of your ex who cheated on you and left you for another woman. I don't think you'd argue that's right.

    is bullshit. But that's because 1) I don't feel that an embryo is a person in the same way that an 8-year-old is and 2) I wasn't talking about purging unpleasant memories. (And even if I was, rape is lightyears beyond mere infidelity.) I was talking about the ability of a rape victim to continue with her life. Having a child changes one's life, regardless of whether it dies immediately or not for many years; regardless of whether it's raised by you or by a relative or a friend or a stranger; regardless of whether you have contact with it or not. Surviving a rape is difficult enough. Surviving a rape but finding your life irrevocably changed, now, that's something I can't conceive of living thorough.

She is the most recent common ancester of all humans alive on earth today w.r.t. matrilineal descent. See the BBC explanation for further enlightenment. The existence of the Mitochondrial Eve is a mathematical fact (unless something like a multiple-origins theory of human evolution i.e. the human species arose independently in different geographically separated populations, and that the present-day ease of interbreeding is the result of a remarkable convergent evolution, is true. Few people subscribe to the multiple-origins theory, and the Mitochondrial Eve observation is a refutation of multiple-origins). Since she has been identified as well (as much as possible,) this is not a theory.

    That said, the chances of mutation from breeding two related individuals may be higher than those of unrelated individuals, but they are not absolute certainties.

    What about the case of a pregnant rape victim?

This is my concern: that people will read your post and think that since you're so right, since people should be responsible enough not to have a child where it is unwanted or cannot be cared for, and since people who have been irresponsible enough to have one anyhow can give it up for adoption, then abortion is unnecessarily cruel and should be done away with.
