I was wondering exactly what I was? We're made up of billions of cells. Am I just a bunch of cells? Or am I SEAN? Or am I DNA's? Exactly what am I?

i would say you are just DNA, and your purpose is to reproduce more DNA

Mm ok. But, if we are just bunches of DNA's then who controls who? Because I'm controlling my eyes, my ears and hands etc.. but it feels like one person?

the DNA gives you some free will, but ultimetly it wants you to get out there and make babies so it can carry on.

you are a parasite...no you are a host for the DNA

Nice simple answer - but too simple.

What about identical twins - they share the same DNA.

What about when you have a viral infection - particularly if it is a retrovirus - that changes your DNA, but does it change who you are?

sometimes the simple answer is the best! Twins, the DNA has still done its job the mother and father DNA successfully reproduced and as an added bonus created double the DNA. this is a great success for the DNA.

the DNA has no control over the infections, this is the problem the DNA has with the host body. it can not control every aspect but we are the best host that the DNA has found.

the DNA may change with infection but it's purpose is still the same....make more, anyway the change in DNA may be usefull to it! it could be a way to further evolve

"Further evolve"

This is a point.. But, surely if the DNA's change, it makes.. I mean deforms us? And overtakes our minds? or something..

I would say that asking what is a person is very like asking what is a nation.

A single animal (human or otherwise) is a system.  the DNA may provide the blueprint for how the system functions, but the blueprint is not the system itself.  The system is defined by the relationship of its component parts (even if every atom of your body is changed, and every cell in your body is changed, so long as the new atoms and cells perform the same functions as the old, and retain the same relationship within the system as a whole, then the integrity of the system is maintained).

Probably, even better, would be to look at the overall behaviour of the system.  We define systems by their historic continuity and their behaviour (i.e. if it has your history, and behaves like you, then it is you, no matter how it is constituted).

yes but you are the host, if you have already made babies then the DNA is not too bothered about what suffering, pain...the host is gonig through. if you have not yet made babies then this will concern the DNA.

Sometimes the simple answer is the best, but that does not mean all simple answers are right.

The point about twins is that if one is defined by one's DNA, then if two people share the same DNA, they are by inference only one person, not two.  By your argument, twins do not have separate identities as separate human beings.

This is a genuine problem, insofar as whether you consider a plant that is taken as a cutting as being part of the parent plant, or do you consider it a separate plant.  More generally yet, animals and plants that reproduce by cloning (vegetative reproduction) - are the daughter organisms really separate organisms or just a distant part of the parent (they do after all share the same DNA).

the DNA has no control over the infections, this is the problem the DNA has with the host body. it can not control every aspect but we are the best host that the DNA has found.

But you are not being consistent here.

You are talking about 'we' as something separate from the DNA - yet if all we are is the DNA, then there is no 'we' that can be regarded as separate from the DNA.  To regard us as hosts for our DNA is totally different from saying we are the DNA.

Again - there is a problem as to what is regarded as an infection.  Past infections with parasites have actually incorporated those parasites into our ancestor genomes, and have helped to make us who we are today; and no doubt that some of today's infections will be incorporated into our descendants and become part of their genome.  At what point does an 'infection' become part of the 'self'?

the DNA may change with infection but it's purpose is still the same....make more, anyway the change in DNA may be usefull to it! it could be a way to further evolve

It is true that the purpose of DNA is to make more of the same - but the point is still what is 'self'.

If today you have one set of DNA, and tomorrow (due to infection) you have a different set of infection, then both your own DNA and the virus are trying replicate, but then the two have become one, and replicate together.  Which then is the 'self'?

What about cancer cells - are they part of you?  What about human cells that are grown in vitro (either from lines of stem cells or lines of cancer cells) - are they still a part of the human being from whose DNA they originated, even though they are physically separate from the person, and have no further part to play in that person's life?

well we care, but the DNA does not.



note: i am making this up as i go along, but it does sound rather good and convincing. i am quite pleased with myself and may have to do more thinking which tends to hurt. maybe the DNA does not want me to know the truth.

What is the 'point' of human beings?  We are - nations are - does there need to be a point.  Systems merely exist because the component parts that make up the system function as a whole.

A nation is a structured conglomeration of human beings, just as a human being is a structured conglomeration of cells - and in each case, it is not the component parts that matter but just the structure they form.

but i answered that, we are just here as a host for the DNA. we will surely die but we are only here as a host for the DNA, once we have done "the business" we have no useful purpose.


George, i will think some more and get back to your questions after a nice bath, i am still formulating my theory.

Not only you.

Just recently – within the last hour or less, I have been having the same problem.

I have been getting around it by positing a message that only contains a single dot, and then modifying the message to contain the contents I actually wanted it to contain.

I suspect someone has 'upgraded' the system with a little buggette, and hoped we might not notice.  We may have to let them know that we have noticed it.

ok, very quickly and off the top of my head.

what is the purpose of the DNA and why once it has made more does it allow you some extra free will, why does it not want you to live for ever so it can make even more of itself.

think of the DNA as the royal family, what is the purpose of the King, Queen or ruling monarch? to make the next king, going around opening fetes and having nice banquites is all well and good but the main purpose is to carry on the blood line.

this is what the DNA is doing, it knows that "we" as a host are not perfect and succeptable to desease and infection but it is the best it has. once you have done your royal duty and made the next generation of DNA it's job is done.



controversial note here and not my opinions just a quick thought.

If god was DNA and not some high being on anothe plain, this could be why homosexuality is frowned upon! no chance of making more DNA.
note i have gay friends...the above just makes sense if DNA was god

bath time...hoping for a eureka moment!

Systems depend upon rules that govern their behaviour in order to sustain themselves.  The DNA contains the rules that govern the behaviour of the cells (note – when we are talking about multicellular organisms, it is the behaviour of the cells the govern rather than the behaviour of the total organism, although ofcourse the behaviour of the total organism is itself controlled by the cells that compose it).  In some ways, the information in the DNA can be seen to be to a cell what a body of law are to a country – the law is a necessity, but not a definition of a country.  Furthermore, a law book does not constitute the law itself, it is merely a form of physical storage for the law – so too, the DNA does not define the rules by which cell behaves, it is merely the physical storage in which those rules are stored.

Yes, it is true that the information that is contained within the DNA (the genes) do perpetuate themselves, and in that respect we are the servants of our genes, but a servant is not the same as his master, despite the relationship between them.

The question was, what are 'we', not what governs us – they are different questions.

In the same way that a member (citizen or resident) of a country, is subservient to the laws of that country, and is required to uphold and perpetuate those laws, but nonetheless the individual person still has an identity that is separate from the law, despite being subservient to it.

The above is partly true.

The complication is that you share genes with other people, and sometimes it is valuable to help your siblings reproduce even where you do not successfully reproduce, because that way at least some of your genes will survive through your siblings children, and if the combined effort gives your siblings children a better chance of surviving than would be possible if you and your siblings were each in competition through your respective offspring, it is sometimes a trade-off worth making.

The most extreme example of this is with worker bees (or similar ranks in social ants, etc.) where the individual will help the hive survive, but will never reproduce themselves.  The situation with social insects is slightly different from the human situation, since the members of a hive all share 100% of there genes, whereas human siblings (unless they are identical twins) will only share 50% of their genes, but 50% is still much better than 0%.

well no eureka moment, but as with all theories they keep evolving. i now wonder if the DNA picked us as a host not because we were the best it could find but because we were adaptive. It may have seen how we evolved and thought that our own evolution would benefit its own evolution.

As humans got smarter so did the DNA.

If the DNA is god then it would know that repdoduction was impossible through homosexual relations, but because we are adaptive and skilled even homosexuals can noe have children through scientific methods - another good reason for the DNA choosing us as a host.

The DNA needs to keep the "blood lines" going for it's own survival and evolution, it is, or at least thinks it is the ruler and in control...or something, i am still working on it.

Yes, George it is fun.

The DNA picking us as a host.. I think that's quite understandable. Just like viruses pick on humans to live on, DNA's do the same?

To imply that DNA picked us is to imply that we can exist without the DNA.

At a genetic level, I would question whether we are any different from just a collection of viruses.  We certainly contain old historic viruses within our genome, and all a virus is is a handful of genes wrapped up in a very simple carrier that inserts those genes into another cell.  We too are genes with all sorts of cellular machinery around it, so if one removes that machinery, a gene is just a gene, whether it was inherited from your parents or from a viral infection, or from a viral infection that infected your ancestor.

Ofcourse, the cellular machinery is an important part of the cell - the gene is merely the software of the cell, it still requires the hardware with which to function (software in the absence of the right hardware is meaningless).

Yeah, that's true that to imply that DNA picked us is to imply that we can exist without DNA.

How about, we could once live without genes/DNA but when DNA entered our body (like a virus), our bodies became immuned to them, and kept them. This triggered the evolving of humans, which is what is left of us now?

good thinking for a non-chelsea fan, i will have to sort this out...

may be, DNA started out as a little piece of code alone in the sea or where ever. like a parasite it eventually needed a host for it's own evolution. first i entered single cell organisms and as it evolved it progressed to infect everything.

one and all are just hosts to DNA

Haha? You've already read that I hate Chelsea? Lol, things spread fast in these forums. [:P] Im a liverpool fan. Muahaha [:)]

Yup, and I also think you're theory is understandable once again. The DNA used to be a little loner in the sea, and needed a revolution. Best choice, us humans.

So where was the DNA created?

The only place where we know DNA is created is within a living cell (not even viruses are capable of manufacturing DNA - they have to use another living organism to manufacture DNA - this is one reason why most biologists would not regard viruses as a living entity).

The trouble is that cells require DNA to instruct them how to build the machinery to create DNA, and DNA requires the cell to get created - very much a chicken and egg situation.

The following is pure speculation:

One would guess that early proto life contained all sorts of mixes of chemical processes, and some of them started to create some sort of cellular structure, and within that cell they started to find ways of storing bits of information they could use to improve the efficiency of their interaction with their environment (possibly even before they had learned to reproduce - these would have maybe been lone immortal cells).  The information would probably not have been stored using DNA, but some simpler process that was sufficient for their purposes.  The trouble is that an immortal cell would only have a limited capacity to grow, and if some of these cells started to grow too much, they would burst.  Some cells would then develop means that, once they grew beyond a certain size, they would develop a partition that would allow each side of the partition to continue processing optimally, but they also then needed to copy the memory storage into both halves of the partition, and so you have memory duplication.  Once the two halves of the cell were partitioned and duplicated, they could then in theory just separate away from each other, and so you now have reproduction.

Only later, as the information needs of the cell increased, I would imagine that they would start using more sophisticated means of storing that information, and then they developed RNA, and later DNA, as an efficient means of storing information.

Ugh. My sister was doing a project on RNAi and all that rubbish. I almost fainted listening to it! Some of it was quite fascinating though.

And yes, I really do wonder where this "DNA" started. Maybe humans just had it within them since the beginning. But how?

george, give me time to make it all up [;D]

at the beginning of time, they were among the early and most primative of...whats the word...things!, during their evolution they had the need to infect others for protection from the elements and predators.

at some point they lost the ability to reproduce naturally and had to have their host do it for them.

The only place where we know DNA is created is within a living cell (not even viruses are capable of manufacturing DNA - they have to use another living organism to manufacture DNA - this is one reason why most biologists would not regard viruses as a living entity).

The trouble is that cells require DNA to instruct them how to build the machinery to create DNA, and DNA requires the cell to get created - very much a chicken and egg situation.


that is true for "the now" but way back in the "long ago" it was not true. the DNA had already affected evolution and as a survival technique had evolved to such an extent that all living cells needed the DNA.

The issue of humans is fairly straight forward - humans are very modern, and have inherited DNA from their ape ancestors, who inherited their DNA from whatever mammal preceded the first ape, and back to the first mammal, and then back to the first animal, and then back to the first bacteria.

The real question has to be how the first bacteria came about.

Modern humans are only somewhere between 100,000 and 250,000 years old.  The first bacteria go back around 4.5 billion years ago.

We have evolved from apes. Why are there still apes and monkeys and chimpanzees and orang-utans still our there today?
