No, the Master says "That's the retinal structure of the human eye." That's like him looking at one of those gene-transplanted tobacco plants -- which we already have in 1997 -- and saying "That's the luminescent compound of a firefly."
The Master never mentions DNA.

So what would you call someone who is the product of two strands of DNA -- one from a human, one from a Gallifreyan -- which have both been tweaked somewhat out of their normal sequences, so that they no longer fit the precise form for "human" or "Gallifreyan" (while still containing much of the same information), so that they can combine successfully?
Me, I'd call it half-human half-Gallifreyan, but then I'm not a geneticist.
But then again, neither is the Master.

Yet while I've seen you post time and again about how the idea of someone being half-human is scientific garbage, I have yet to see you post once about the equally garbage science behind the Krynoid, or regeneration, or the Androgum inheritance, or any of the other times Doctor Who waves its hands vaguely in the direction of genetics.
That, in a nutshell, is the double standard.

All right, just one more time: As a general rule, canon=what I like, not canon=what I don't like. In the case of the "Is the Doctor really half human" question, my intuitive answer is no-I don't like the idea any more than (some of) you do-yet at the same time I can see how it could be made to fit established Who history, for example it makes a dandy explaination for why regeneration always seems a riskier proposition for the Doctor than for the other (no pun intended) presumably "full" Time Lords/Ladies (Borusa, Romana). This thread seems to me to be an example of how you can pull up facts (from Who or reality) to support any argument you wish. There are probably arguments that could be made to support scientifically the idea that he could be half human, but if you're not looking to support that, you're not going to find them. Anyway-enough of my 2 bits worth.

Pardon me, I stand corrected. "Double standard" seems to be a moral judgement to me, but I take your point. It doesn't have to be. All the same, as I've explained, I cringe on both the reversed polarity of neutron flows and half humans (also, though not previously mentioned, whatever that thing was that was made out of teacups, spoons, and used tea leaves to detect the Master's TARDIS, also "living metal," also a few other things that I can't recall at the moment.)
The thing with the neutron flow is a god out of the box device. It frustrates me storywise because I'm set for a scientific explanation and then there is none. But it's an episode by episode thing. It does NOT show up in lots of episodes. The half human thing grates on my nerves because it's a hackneyed and sentimental device (as well as impossible) that didn't even keep the story stitched together. And it keeps hanging on. At least the series "outgrew" reversing the polarity of the neutron flow.
There are inconsistencies and impossibilities in the premise of the show as it was set up that the viewer had to accept just to get going (like time travel), But these were interesting concepts in and of themselves (time travel). And there were inconsistencies necessary just to keep the series going (like regeneration to replace Hartnell with Troughton). These contribute to my distaste of stuff that's nonsense that is *not* necessary to keep the series going, especially stuff that's been used before and is not interesting. *And* is impossible.
I'm sure that even now as we speak, Kate, you are organizing a couple ideas on how technology could create/engineer a half human creature. I look forward to seeing it, because I don't think it's possible, and it has nothing to do with technology. And my researcher at Glaxo Wellcome is telling me I'm right.

1. I believe that someone has already mentioned spin, so yes neutrons can have polarity.
2. It would seem possible that as DNA encodes information that information could be encoded in a different chemistry, just as the code can be written in letters instead of DNA. An alien biochemistry could therefore be mapped into DNA code, and vice versa. Alien hybrids could therefore be produced, but only by a system which interpreted the meaning of the genes, rather than relying on chemistry to do the job for you. I believe John M Ford came up with something like this in a Star Trek spin-off novel to try to give a convincing explanation to paper over the Star Trek script writers ignorance of genetics. Doesn't stop the half-human stuff being a bad idea, but sufficiently energetic hand- waving can work wonders.
3. Parallel worlds are a scientifically respectable idea.
4. It is possible to come up with a technobabble explanation as to why a sculpture made out of a wine bottle, corks, forks, and tea-cups would interfere with the workings of a time machine. It involves the statistical distribution of parallel worlds in the multiverse.
5. I once had responsibility for some equipment which had a setting labelled "polarity". I never had to reverse it though, which was most disappointing. -- Ken Mann Still taking the tablets.

But the tobbaco plants are still tobacco plants. They are not half firefly.

So I'd gather, but the person could not be a product of two strands of DNA, one human and one timelord. That's the impossibility. The two strands are not compatible. A timelord has two hearts, a different respiration system, and a different circulatory system. That DNA is not going to combine with DNA for a creature with such vast differences in metabolism and structure, not any more than the mating of a human with chimpanzee would produce offspring. And the physical differences between humans and timelords are much wider than the physical differences between humans and chimpanzees.

Jon, what I choose to post about is only what I choose to post about. What I think about these ideas as I run across them is in my mind, and you can't know it. I'm sorry--you are not the posting sheriff of the newsgroup, assigned to note and report on people who post more heavily on certain things than on others. Well, maybe you are, but it doesn't affect me.
If it pleases you or assauges your feelings to note I have a double standard, you can certainly do it. It does not at all detract from my point that the half human thing is tripe, which it is. It's still tripe, no matter what standards I employ. But I hated the androgum story so much that I never noticed anything in there about genetics. It was so wretchedly boring and repetitive I started house cleaning, as I recall, and only stopped to watch the scenes with Patrick Troughton. There is such a thing as giving up on a story before you even find all its absurdities, you know.
But finding and being repulsed by the half human thing does not create any obligation in me to find every other scientific blooper in DW. It's enough to know that that one stinks. I haven't even *seen* all the stories in Dr. Who--just all the Pertwees. If the one with the Krynoid is the one I think it is--with Tom Baker and the big house and the mulchig machine that nearly everybody got thrown in to, that was sort of like the androgum story. I was stupefied before I got to any explanations.

Nevertheless, they are genetically part-firefly. Would your objections to those scenes in the movie have gone away if the Master had said "The Doctor is genetically part-human" rather than "The Doctor is half human"? Or if the Doctor had said "I'm genetically part-human on my mother's side"?
Somehow I doubt it -- because, as I've said, it's the *idea* of the Doctor having human ancestry which you loathe, and you're just seizing on a "scientific" reason to bash it.
>>So what would you call someone who is the product of two strands of DNA -- >>one from a human, one from a Gallifreyan -- which have both been tweaked >>somewhat out of their normal sequences, so that they no longer fit the >>precise form for "human" or "Gallifreyan" (while still containing much of >>the same information), so that they can combine successfully? >>Me, I'd call it half-human half-Gallifreyan, but then I'm not a >>geneticist. >So I'd gather, but the person could not be a product of two strands of >DNA, one human and one timelord.

Read my question again, this time paying special attention to the bit that says "which have both been tweaked somewhat out of their normal sequences... so that they can combine successfully," and then try answering it again.
Yes, such tweaking (the creation of a new carrier to allow you to combine incompatible genetic material on such a scale) is beyond the realm of current human technology. But it's not theoretically impossible -- and I'll be glad to point you to folks from the Hughes Institute who'll back that up.

>If it pleases you or assauges your feelings to note I have a double >standard, you can certainly do it. It does not at all detract from my >point that the half human thing is tripe, which it is.
Actually, it does detract from it -- since it's now been shown that the standard you're citing to prove it's "tripe", scientific impossibility, would also cause much more accepted ideas (like regeneration) to fall into the "tripe" category. So if you don't think these other things are tripe, then it suggests there's something wrong with judging just on that standard.
Again, if you'd just say you don't like the Doctor being half-human, there's nothing wrong with that. Pointing out that it's not necessary? That's a fair cop. That it could potentially be used in really cliched ways, a la Spock? Yep. But focusing on scientific impossibility is a seriously flawed argument -- and bringing the matter up over and over again without adding anything new gets really boring too.

If you read above you will see that you stated that electron flow is voltage. I have a MS in electrical engineering CS and I tell you this is not true. Voltage is the potential difference between the positive and negative charges that result in electron flow. You are correct that electron flow cannot occur with out voltage but electron flow is current not voltage. Any electrician will tell you that "Voltage can't kill you - it's the current that does the job."

Correct even though neutrons can flow. Anyway, I always felt the Doctor was talking metaphorically.

True. But if the mutation affects the retina system making it less efficient it would be very hard for the species to survive long enough to adapt. There are plenty of competitor species out there waiting for a chance to nudge another aside and into extinction. However, I agree that it is not impossible - just highly improbable.
I also never said that evolution would produce the perfect life form. This would be quite foolish since neither I, nor anyone else, knows what the perfect life form might be - if there is such a thing. What I did say was that successful species survive by being efficient at finding food and not becoming food for someone else (well, maybe not in those words). The name of the game is survival and any mutation that hinders survival spells extinction.

Well - based on the theory that the human race was fostered by the TLs to begin with. And that TLs and humans are both humanoid while a chimp is a primate.

I don't understand where you came up with the "one generation" theory. I had believed that the Doctor if half human had always been so. And I do not recall anyone (Master or Doctor) ever saying the Doctor was the result of a sexual liaison between a TL and a human. "On my mother's side" could mean anything - a human female's DNA spliced with a male TL's.

Well I agree that he'd be a TL but that doesn't mean he would have some human characteristics. So little is really known - genetics at this level is a very new science. 2000 years ago the idea of DNA would have seemed preposterous.

In fact, we know nearly *nothing* about what it means for the Doctor to be half-human. Wisely, the TVM steered clear of the details - when "The X-Files" is vague about genetics, it gets it right, but when it goes into detail, it messes up. :-)
We certainly weren't told enough for you to conclude that it's a genetic impossibility. Sure, the Master says, "See that? That's the retinal structure of the human eye". But if I looked at a mule, and said, "See that? That's the ear structure of a donkey", would you still argue it was a genetic impossibility?
Have you read "The Also People"? There's a fascinating sequence in which we see a powerful alien biology at work, translating and editing human DNA, selecting the best genes and throwing out unwanted characteristics. In principle, that's no different to what a genetic engineer can do in the lab - but imagine if that lab was on a fabulously advanced computer, or was even the body of an organism with powerful genetic engineering capabilities of its own!
Because we don't know exactly what it mean for the Doctor to be half-human, we can't claim it's impossible. For instance, what if his mother was human, but his Time Lord genes dominate - so his human heritage only shows up in subtle ways, as in the retina? What if humans and Time Lords are actually closely related, so you'd only notice human characteristics on close examination?
As you can see, with a little imagination, it's no more impossible than anything done in a genetics lab today. And that's because, sensibly, they didn't botch it up by trying to give a wonky scientific explanation. It's a mystery.

What if it *was* the result of his parents having sex? What if his father's sperm carry genetic tools to help incorporate the human DNA, or his mother took a special drug, or some nanites, to help the process? This is SF - we can imagine all kinds of technological advances and possibilities.
It's those "Why?"s which provide future story opportunities. As I said, it was probably being set up to be explored in a (hypothetical) series - they didn't want to give away too much at the beginning.
>Along the storyline it stinks because it contradicts what came before, >and it is so hackneyed and sentimental. We've had enough of it with >Spock and Qwai Chang Cane.
It never had a chance to *be* hackneyed and sentimental. It could certainly be used that way - endless quests for the Doctor's parents, blah blah blah. But it wasn't used that way in the TVM - it was barely touched on.
An interesting fact from "The Nth Doctor" is that Spock *was* the inspiration for the Doctor's half-humanity - but not in the way you'd expect. Instead of having him long for Earth or feel torn between two planets (feeling like a mule? :-), the writers had in mind Spock's strained relationship with his father. Interesting story material, that.

As I said, whether the half-human thing really is a contrivance or a cliche would depend on how it was eventually used. As it was, we never got a series to explore it - and we won't be touching on it in the BBC Books. As an idea, it's sadly dead in the water.

Did you mention to those researchers that you were talking about an unimaginably advanced species? See above for a few ideas which, given the technology, might make a half-human Doctor plausible.
btw, *I* have a respiratory bypass system. It's called myoglobin. It's nowhere near as efficient as the Doctor's, but it does stop my muscles running out of oxygen when I'm out of breath. And until we know how regeneration works, there's not much point in debating whether it's a scientific impossibility. :-)
And that's true for the half-human thing - we have to drop our assumptions, because we don't *know* what the genetics are. And that means we *can't* insist it's impossible - we simply don't know. That leaves us free to imagine.

It's surprising how a small genetic difference can produce such different creatures, which is think is the reason to mention the chimp. After all, Jon and I are virtually genetically identical - but I've got entire *organs* that he doesn't. :-) (And that's likely to be the result of a single gene difference!)
Let's play with the idea that humans and Time Lords are related. It would not only explain the half-human thing, but also why the Doctor looks so similar to us - there are important differences, but he can easily pass for human. (Could a chimp?) That ability to hide amongst humans would make Earth an attractive refuge for a renegade... as for the second heart, could it be a result of the first regeneration? A result of a few extra genes, as in human sexual dimorphism? Or something like Larry Niven's Pak, who start human and grow a second heart when they mature into "aliens"? What's the relationship between Time Lords and humans - are we their descendants? Their ancestors? Some kind of off-shoot, or experiment?
As you can see, all sorts of possibilities open up when you start to mess around with the half-human thing. With a bit of imagination, it need not be limited to the obvious cliches.
>And it seems that there are other significant differences as well. >But taking your point, a chimpanzee is still a chimpanzee, and in >spite of being within 1% (if that is accurate), a chimpanzee still >cannot successfully produce offspring with a human.

This is circular, in a way - the *definition* of a species is a group which can produce fertile, healthy offspring under natural conditions.
You'll notice the definition doesn't say anything about *un*natural conditions, like the involvement of mind-bogglingly advanced technology. :-)

Point of order. When Jon says you use a double standard, he's attacking your argument, not your person. That's why he uses examples from your argument - not from your personal life, or something - to back up his claim, as I did.
"Morality" has nothing to do with it; the logic, precision, and accuracy of your arguments does.

Well, no. The chemical nature of DNA, and developmental embryology, are two very different things. "What DNA is" has nothing whatsoever to do with the argument, unless you're trying to say that a half-human Doctor would have to have hybridised strands of human and Gallifreyan DNA, which is nonsense.
And is the "pattern" "entirely different"? That dead embryo is clearly human - not "entirely different". But something went wrong - and it might not have been something genetic.
Think of DNA as the magnetic medium on your hard drive. When you run a program, you don't think in terms of tiny bits of magnetised metal, but in terms of programs - the instructions which tell your computer what to do.
Now, a lot can go wrong. Your hard drive could be physically corrupted - the equivalent of damage to the DNA. The instructions could be scrambled by a bug or a virus - missing parts of genes, whole missing genes, genes which code for the wrong proteins. Or there could be a completely extrnal problem, like a power surge - just as radiation and drugs can mess up an embryo's development.
Now, let's say that extra heart is the equivalent of a whole extra part of your program. But in a human embryo, it's a mistake - caused by a bit of damaged DNA, a scrambled instruction, or something outside the embryo itself. The embryo can't cope with this extra organ, and it dies.
But what if you changed the program? What if you altered the embryo's genes so that it *could* handle the extra organ - built in those extra systems? Even with today's genetics, that's *theoretically* possible, even if it's a long way off.
So the mistake which kills the embryo could become a deliberate change - given sufficiently advanced technology. The dead two-hearted embryo is no proof that you couldn't *create* a two-hearted, half-human Doctor.
It's also no proof that humans and Time Lords couldn't share some kind of common ancestry. People are being born today who lack some of the useless toe joints we still have. Maybe, in some distant past, we lost our extra heart - or the at least the genes which made it possible. Maybe the Doctor's mother still had those genes, quietly dormant, and they were simply reactivated in her son, thank to Daddy's DNA.
Of course, all of this is speculation. But it's all based on science. And that's what SF is all about.

I'm sorry to keep hammering this point, but the Master - and the TVM - never refer to genes or DNA. All the Master says is, "That's the retinal structure of the human eye. The Doctor is half-human."
Grace looks at the Doctor's blood and says, "It's not blood." We dont' know exactly what she was seeing, but if his blood isn't recognisably human, why should his DNA be?
The problem here is the assumption that the Doctor is (a) totally unrelated to humans, and therefore genetically incompatible with them, and (b) that he's the result of a simple cross, no high technology involved at any stage.
Cling to those assumptions, and a half-human Doctor is impossible. Recognise that they *are* assumptions, and that they could be wrong, and a world of possibilities - and possible stories - opens up.

I find this line of argument hard to understand.
When you say "changed from what it is", when you say "properties", what do you mean? The TVM and the show don't mention DNA or genes. And the TVM doesn't say that the Doctor is human, or that he has human DNA.
Is the horse DNA in a mule's cells no longer horse DNA? If so, which "properties" have changed?

For pity's sake, that's arguing by authority; a technique most usualy employed by religious fundementalists.
"A scientist has said......" Take you pick. Somewhere somewhen a scientist has said any thing you can think of.
What are this researchers arguments to back up your case?

The Doctor's so-called "half human" attribute is not the result of many generations of development of characteristics but the result of a single mating--whether sexually or artificially. He did not evolve into a half human or partially human creature. I'm saying that as far as I can see it is apples and oranges reasoning. Cross breeding between disparate species does not have a lot to do with evolution. Two different arguments.

So are you saying that because we don't know it's okay to assume it could work? But we do know--we know that it wouldn't work. Timelords and humans obviously have common characteristics (two hands, two feet) but also many widely disparate characteristics--too disparate for the DNA to be similar enough to combine. The entire circulatory system of a TL must be diferent from that of humans, and respiration is different too. So there would be differences even down to cellular levels in the methods by which oxygen would be transferred, waste transported, etc.

They're listed above (well, and below, too). I'm waiting for the counter argument. But somewhere in the thread it was indicated that since I'm not a geneticist, I cannot make the claim, so I am keeping up with a geneticist on it. But my own point is simple. Human DNA is human DNA--or it is not. There is no such thing as a creature that could be parented by the characeristics of a TL combined with the characteristics of a human and be "half human."

Oh, there you go, playing mind reader again. I think that any pointer to human ancestry raises the question that it's contradictory to the previous storyline, but also that there's no reason for it. Why would a better adapted race try to graft in human genes? The illogic of it does bother me.
But again, the tobacco plants are not reckoned as having firefly parents. They are tobacco plants, and a gene has been engineered into them. They are not half firefly, and nobody talks about a firefly parent of the tobacco plants, but rather a single firefly characeristic.

A tweak would not do it. The two systems are entirely different. A cardio-vascular system cannot be half human and half TL. It has to be all one or all the other. And if the cardio-vascular system goes one way, then the respiratory system would have to go that way to, and things like cell wall strength would also have to go that way. Tweaking will not do it. Maybe somebody could take all available characeristics and completely structure something else, but that would be an entirely new design.

No it's not Jon, because it still remains true--regardless of my standard, which is off the point anyway. He could not be a combination of two such different species.
And as far as I can see, I've acknowledged and offered a pretty long defense of the chief scientific nonsense of the era that I keep up with--the polarity of the neutron flow. Efforts to make me responsible to point out all scientific flaws in the rest of DW--when I don't even like the other Doctors (except for a new fondness for Troughton)--to somehow justify my right to point out this particular flaw, are meaningless. It's a flaw, and I'm pointing it out.

He says "Reverse the Polarity" in TERROR OF THE AUTONS. Brad F. mentioned that the entire phrase ("Reverse the polarity of the neutron flow") shows up in SEA DEVILS I noted it in TIME MONSTER, when the TOMTIT machine is running amok. The Doctor yells the directive to the woman scientist, and she seems to know what he means, because she pulls out a component of the machine, reverses it, and reinstalls it. He says it again in FRONTIER IN SPACE when he turns the sonic screwdriver into a magnet. There may be more, but those are the ones I can recall in context.
I think somebody mentioned early in the thread that Troughton said it. But maybe the person meant Pertwee.

Okay, here goes. I have a two year degree in EET. There came a point in the course work when we just jumped from saying E (for emf) and then started calling it V (voltage). But our teacher definitely warned us (since we would be the people handling the electrical equipment) NOT to adhere to the adage that voltage won't kill you; current will, because voltage had to be there for current to be there, and that very high voltage with very low current would indeed kill a person. This was proved out when a painter at Vogel Nuclear plant stood up between two discharge spheres and caused an arc. No current flowed until he made himself the other end of the potential difference for a discharge to ground. He was killed. And on t he other end of the question, people who work from a floating ground can mess with live wires. Though the current may be high enough to kill, the floating ground prevents the discharge. Not that *I'm* going to try it. I turn stuff of at the breaker box.
This is purely asking for clarification. I think the Doctor was talking in the 70's, when anything was possible as long as it sounded sufficiently complex.

Pertwee used the phrase in the Five Doctors.

No, no, no, NO! These are classic Science Fiction standards! (read- cliches) Where would the show be without these? Esp. time travel (yikes).
