Biosemiotics is a growing field of semiotics and biology that studies the production and interpretation of signs and codes in the biological realm. Biosemiotics attempts to integrate the findings of biology and semiotics and proposes a paradigmatic shift in the scientific view of life, demonstrating that semiosis (sign process, including meaning and interpretation) is one of its imminent and intrinsic features.
To define biosemiotics as “biology interpreted as sign systems study” is to emphasize not only the close relation between biology as we know it (as a scientific field of inquiry) and semiotics (the study of signs), but primarily the profound change of perspective implied when life is considered not just from the perspectives of molecules and chemistry, but as signs conveyed and interpreted by other living signs in a variety of ways, including by means of molecules. In this sense, biosemiotics takes for granted and respects the complexity of living processes as revealed by the existing fields of biology – from molecular biology to brain science and behavioural studies – however, biosemiotics attempts to bring together separate findings of the various disciplines of biology (including evolutionary biology) into a new and more unified perspective on the central phenomena of the living world, including the generation of function and signification in living systems, from the ribosome to the ecosystem and from the beginnings of life to its ultimate meanings.
Furthermore, by providing new concepts, theories and case studies from biology, biosemiotics attempts to throw new light on some of the unsolved questions within the general study of sign processes (semiotics), such as the question about the origin of signification in the universe.
Traditional biology (and philosophy of biology) has seen such processes as being purely physical and, being influenced by a reductionist and mechanistic tradition, has adopted a very restricted notion of the physical as having to do with only efficient causation. Biosemiotics uses concepts from semiotics (in the sense of C.S. Peirce as the broad logical and scientific study of dynamic sign action in humans as well as elsewhere in nature) to answer questions about the biological emergence of meaning, intentionality and a psychical world.
These questions are either hard to answer or completely incoherent within a purely mechanist and physicalist framework.

In your best opinion can you describe the most probable events that caused DNA to be formed and utilized?
My opinion is that DNA came from RNA and was originally very simple in comparison to today. As genetic mutations began happening and altering various organisms, it became more and more complex along with the various lifeforms. I believe one of the bigger steps in the evolution of DNA happened during the emergence of multi-cellular life, a process that in itself took around a billion years.
This is why I dislike the appeal to DNA complexity arguments. They essentially try to argue that DNA was designed in its current form, which does not make any logical sense.edit on 9-6-2013 by Barcs because: (no reason given)

And I asked you how DNA formed and was originally created, you gave me one very general sentence regarding my question and then the rest is what happened after. "My opinion is that DNA came from RNA and was originally very simple in comparison to today"... Obviously im going to want to know how you think RNA formed and was utilized. if you dont mind. This argument is about the origins of the code.
The laws of physics created RNA, the laws of physics created DNA, the laws of physics created organisms, the laws of physics evolved those organisms etc. The laws of physics created humans. (biology and chemistry just being advanced forms of physics, for biology and chemistry were created and allowed by the laws of physics, biology and chemistry and extended aspects of physics), How will you respond if I say, what you call intelligence does not exist. Only the laws of physics exist. Everything humans do is because the laws of physics allow them to, and because humans are creations of the laws of physics.
Like a dog or dolphin, they can follow commands, they can learn, they are aware, they have emotions, they can be smart. But those intelligent animals are not able to conceive or create something like DNA running an intricately complex organism. How can stupidity (universe) achieve something so incredible such as trillions of complex living organisms programmed by subtle evolution friendly codes, inventing consciousness and the brain, and (all organism body parts and mechanics, skeletal, circulatory, nervous, visual etc.) intelligence. Yet what you may refer to as intelligent ( a dog for example) can never even come close to thinking of creating what nature has created. In fact probably 90% of all "intelligent" humans could have thought to create DNA and the human body.
Something else I wanted to ask. In a post to me you mentioned 'random' (maybe it was dragonrider) and the fact that it may disprove intelligence in/of the universe. Is intelligence capable of being random? Is intelligence capable of being non intelligent? Is non intelligence capable of being intelligent? Would it be intelligent for an intelligence to design a system that utilizes randomness (in confines and parameters/laws of course) to achieve 'events' or a goal?

But they are, because they are appealing to the complexity of DNA as it is NOW and using it to suggest an intelligent designer is necessary because it has a code. They aren't talking about RNA or DNA in the ancient past. They are just assuming the "code" was always there, but we don't have ancient DNA samples, so we don't know.
You asked for my opinion, not my scientific analysis, so I kept it simple. Obviously if DNA formed FROM RNA, that would be its origin, just like a dog evolving from a wolf ancestor would be considered the origin of that particular species. IMO, RNA formed from amino acids and other materials mixing together in the right conditions. Over time it evolved into DNA. I personally believe that abiogenesis and RNA world hypotheses are both the closest we have to answering that question, but I don't necessarily agree with all of it. I also believe that panspermia / comet impact events are big parts of RNA/DNA evolution as well.
For the origin of code: What is the "code" of DNA? It is groups of pairs of atoms. Origin of code is a misnomer. The code is physical. Why wouldn't the "code" two billion years ago be comprised of various pairs of atoms, only much less of them in a much simpler molecule? It makes sense considering lifeforms were much simpler back then. They wouldn't need a complex blueprint for a single cell, you just need mechanism for it to replicate itself. Why does this physical "code" need a special type of non physical origin?

I'd argue that humans cannot yet create DNA or anything like it, therefor an intelligence capable of such a feat would far surpass our own. It's all relative. To humans, it might seem complex, but to a creator race it would probably be easy to them. It's not 'stupidity', it's universal forces and matter/energy acting upon one another. How exactly consciousness arises is a tough goose to cook, but that alone isn't reason enough to assume creation, IMO. We might not have an explanation right now other than a hypothesis about shrooms, but 50 years down the road, we might. It's really cool to ponder about, however.
This is why I enjoy conversing with you much moreso than Squiz and the others. The conversation actually progresses and is enjoyable to read & philosophize about. I appreciate the details of your post and the lack of insults, denial and fallacies. It is quite refreshing.
The problem with that type of thinking is that laws are not conscious entities. The laws themselves didn't create anything, they merely allowed for it to happen via other events. Yes, all humans, and all objects in the universe must obey the laws of physics. There is no choice in the matter. I see what you're getting at, though, it's still a big mystery.

As the National Academy of Sciences acknowledges, "Two amino acids do not spontaneously join in water. Rather, the opposite reaction is thermodynamically favored." In other words, water breaks down protein chains into amino acids (or other constituents), making it very difficult to produce proteins (or other polymers) in the primordial soup.
Origin of code is a misnomer. The code is physical.
I'm not a big fan of the word random. Nothing is random. Everything has a cause.

I think many have fallen into the materialistic trap of viewing the world and all it's wonders as something mediocre, when there is nothing mundane about it at all. Live and relish in the mystery I say, you may just find it will enrich your life.
