Phumox? What's that?
The Phumox project (established February 2005 by Andy Gracie (hostprods)
and Brian Lee Yung Rowe (muxspace) has as its aim the exploration of collective
intelligence, organic development and interplay with the dual concepts
of symbiosis and parasitism. Phumox examines the notions of data and information
systems inherent in the living organic environment and how Artificial
Intelligence can be used as a tool to explore them, intervene in them,
establish relationships with them and ultimately to become a part of them.
As we move deeper into an age where the line between the natural and the
technological becomes increasingly blurred and easily bent, Phumox poses
questions such as: What constitutes our notion of 'being' and how are
awareness and consciousness embodied through information networks? Invoking
the notion of the cyborg is inevitable, though Phumox should be seen as
a discussion on the wider issues of the junctions between organic and
inorganic, natural and artificial. Phumox is more interested in how complex
multiple relationships are formed via the exchange of data than in how
a single agent can be augmented or "improved".
Phumox attempts to circumvent the limitations of traditional silicon-based
von Neumann machines by exploring new forms of computing using organic
systems but not to be confused with techniques such as DNA computing or
using Zhabotinsky fluid style chemistry as the vehicle for computation.
Rather, our "organic intelligence" is a self-contained system
that behaves in a predictable fashion to perform some functional, artistic
(and possibly computational) task.
A crucial part of Phumox is the recognition of emergent behaviour in organic
and artificial systems and how these organic and artificial systems can
be juxtaposed to produce emergent behaviour through symbiotic or parasitic
activity. Exploring these boundary conditions is the focus, as the most
dramatic events occur not in equilibrium but in change. For example, the
traditional version of collective intelligence can be interpreted as a
form of symbiosis. The Phumox perspective is to ask what are the consequences
of creating an environment that promotes a collective intelligence that
embodies a relationship closer to a traditional view of parasitism?
By employing the ideas behind Phumox in a range of installation works,
presentations and papers we intend to create an epistemological landscape
for reflection, contemplation and discussion of the many issues around
our complex and changing relationships with the organic. In particular
we take issue with our access to the organic, our ability to literally
deconstruct, to appropriate, to re-imagine and to reconstruct. We see
it as necessary to explore our visions of what new evolutionary processes
and procedures may be revealed by the probings of bioscience and the demands
of bio-industry. Phumox embraces the notion that a considered cultural
response is vital to the successful navigation of the 21st century and
its reinterpretations of the nature of life.

the sliding scale of Parasitism and Symbiosis and their effects on evolutionary
change
Parasitism and symbiosis are two simple words that hide myriad complex
relationships between various organisms. It is commonly believed that
'parasitism = bad/negative/destructive' whereas 'symbiosis = good/positive/constructive'
though much evidence points to the fact that things are far more complex
or much less black and white than that - as they so often are in matters
of life, death and reproduction. Maybe we need a few choice definitions
to get going;
Symbiosis, as proposed by Heinrich Anton de Bary in his text 'The Phenomenon
of Symbiosis' (1879), simply means a close association between organisms
of different species. At the 'friendliest', most harmonic end of the scale
we find Mutualism, which as the name would suggest is an association in
which both organisms derive mutual benefit, or that each of the interacting
species functions as both a host and a parasite. Phoresis is a fairly
loose association and is a specialised form of commensalism in which one
organism (the phoront) is usually smaller than the other and uses the
larger organism as a transport host. Next up is Commensalism, an association
in which one, usually smaller member, benefits from the association, whereas
for the other member the association is neither beneficial nor harmful.
Parasitism is characterised by a range of definitions including the following:Parasitism
is an intimate and obligatory relationship between two heterospecific
organisms during which the parasite, usually the smaller of the two partners,
is metabolically dependent on the host. [T.C. Cheng; General Parasitology.
Academic Press 1986.] and my personal favourite (and most appropriate
bearing in mind the concept of the Phumoxian host) Parasites are those
animals which use other living animals as their environment and source
of food, at the same time relinquishing to their hosts, partially or completely,
the task of regulating their relationships with the external environment.
[V.A. Dogiel; General Parasitology. Oliver & Boyd 1964.
Parasites and symbionts are normally considered as the two extremes of
an interaction between organisms in which one is termed host, and the
other, according to the degree of injury it inflicts or benefit it bestows,
is parasite or symbiont. Therefore the concepts of parasitism and symbiosis
may be employed in the same sense as both refer to the same general phenomenon.
In fact, the classical definitions of mutualism, commensalism and symbiosis
do not contain any specific cut-off points that distinguish them from
parasitism.
'The parasite-host-environment system is dynamic, with several points
of equilibrium. This makes it difficult to trace the thresholds between
benefit and damage, and therefore, the definitions of commensalism, mutualism,
and symbiosis become worthless.' [A. AraČjo et al; Parasitism, the Diversity
of Life, and Paleoparasitology]
These shifting relationships have been a driving force for evolution since
the first vague traces of organic matter appeared on Earth. If we follow
the Serial Endosymbiosis Theory of Lyn Margulis we see that complex eukaryotic
cells (cells which have their genetic material in a nucleus) came about
from endosymbiotic relationships between various microbial life forms.
In fact, in may instances the theory goes that many relationships began
parasitic, became symbiotic and later evolved into a whole discreet organism.
Symbiosis was, and continues to be, a force for evolutionary change -
life just finds it convenient. We also find evidence that parasites have
had their fair share of influence in evolutionary matters as the efforts
by their hosts to be rid of them, their escalating arms race, is a major
cause of biological diversity. 'Not only are parasites the most successful
life forms on Earth, they triggered the development of sex, shape, ecosystems,
and have driven the engine of evolution'. [Carl Zimmer; Parasite Rex]
So symbiosis, parasitism and all the forms of inter-organism relationship
along the line between the two are driving forces for evolutionary change.
I like to extrapolate from this that the very act of an agent, organic
or otherwise, existing in close biological or ecological proximity with
another is a force for evolutionary change. And here is where the Phumox
project wants to butt in. Maybe the Phumox project, via some form of artistic
activity can provide such an agent as a player in a bio-artificial ecosystem.
By inserting some form of intelligent device into an organic environment
and modulating its behaviours and modes of interaction between more symbiotic
or more parasitic what kind of emergent effects can we observe? Would
the resulting system be an evolved life form or would the changes and
adaptations of the natural organisms involved exhibit some form of Lamarckian
evolution due to the new and strange stimulus in its environment?
- the observer as a force of change
One of the fundamental concepts of quantum theory, or more accurately
an aspect of it known as the Heisenberg uncertainty principle is that
an event is determined or altered by the act of observing it. Or more
accurately again, that everything exists in a probability cloud and the
act of observing an instant 'fixes' reality at that moment. In the famous
'Schrˆdinger's Cat' thought experiment the probability cloud is pretty
small - the cat is either alive or dead - though in more complex situations
the probability cloud can grow to enormous proportions.
The observation of nature virtually excludes the possibility of complete
objectivity and detachment. As Heisenberg himself said "What we observe
is not nature itself, but nature exposed to our method of questioning."
So is reality more matter-like or more idea-like? Such a view of nature
is obviously speculative, and raises questions about what kind of observer
is necessary... could it be anything?
So could it be some kind of Artificial Intelligence enhanced robotic agent
inserted into a bio-artificial ecosystem? (Bearing in mind that as we
approach the sub-atomic level the distinction between organic and non-organic
begins to break down). Could the observing of the organic system alongside
the symbiotic/parasitic nature of its relationship be a strong evolutionary
force? The Phumox project would like to think so. Perhaps, we have two
ways now of stimulating responses and forcing evolutionary behaviour in
our ecosystem.
- natural genetic mutation in bacteria and other cells
'Evolutionary genomic change occurs largely by a process of Natural Genetic
Engineering. Systemic genome organization means that new functions arise
by the cut-and-splice rearrangement of genetic modules. Living cells possess
mobile genetic elements and other biochemical functions which carry out
the underlying DNA rearrangements. Cells regulate the activation of natural
genetic engineering functions. Thus, cells have a capacity for major genome
reorganization in response to evolutionary crisis.' [J A Shapiro; 21st
century evolution]
It is becoming apparent that natural genetic engineering is a relatively
common activity in cells in general and also in small whole organisms
from bacteria to the fruit fly. They are 'consciously' altering their
own DNA, and turning on and off of genes according to environmental conditions.
The necessary conditions can range from stress (lack of food or biological
attack) to the need to perform some other activity (colonise a plant or
other creature), in fact it seems like it can be anything that the colony
wasn't already happily doing. It has been demonstrated, for example, that
if E. coli bacteria are plated on media containing high concentrations
of a nutrient they cannot use, they begin to mutate much faster than the
normal 'spontaneous' or 'random' mutation rate, but only in the genes
that will then enable them to use the nutrient and to grow.
Genes and genomes need to be fluid and adaptable to maintain stability
on the one hand and to respond to environmental challenges on the other.
This is the essence of organic stability, as opposed to mechanical stability.
It is also becoming clear that the 'fluid genome' processes are a complex
regulatory system for carrying out the 'natural genetic engineering' on
which life depends. [Mae-Wan Ho]
The popular wisdom is that genes and the organisms containing them that
'respond' successfully to environmental challenges are not acting randomly
but purposefully, pointing to an instinctive intelligence that is beyond
purely physical mechanisms and processes. Whether this process has any
evolutionary direction is still open to question, though it is likely
that over a period of time useful genes could remain switched on and the
bacteria would remain in the environment to exploit their new niche. This
is getting particularly close to a new species.
We ask ourselves at this point: Can Phumox create an environment of persuasion,
stimulation or threat that would lead to the spontaneous mutation of bacterial
DNA? Can it attempt to quantify genetic manipulation without getting its
hands dirty? And if so, how would our reality changing, quantum observing,
parasitic/symbiotic force for evolutionary change, natural genetic engineering
stimulator recognise the effects it was having? Once embodied as an 'idea'
in the 'mind' of our artificially intelligent agent this notion of evolution
would need to be broadcast, replicated, disseminated.

memes and genes
The term 'meme' was made popular in Richard Dawkins' 1976 book 'The Selfish
Gene' and was defined as "a unit of cultural transmission, or a unit
of imitation". Although in the emerging science of memetics there
are differing interpretations of the word it is generally agreed that
a meme consists of some sort of a self-propagating unit of cultural evolution
that resembles the gene. Memes have become increasingly popular amongst
cultural commentators as they are particularly useful in explaining human
behaviour and cultural evolution whilst maintaining connections and metaphorical
links with the highly fashionable science of biotechnology.
The notion of a meme as an idea or a thought that is contained in a word,
or a collection of words as a sentence forms an analogy to the idea of
a gene as a self-replicating set of code. The gene can be viewed as a
collection of nucleotides that replicate together and code for some set
of behaviours or body parts. DNA strings seen as code, the code of life,
is not a new idea, but a well established meme.
Mutation is necessary for memetic evolution just as it is for genetic
evolution. Via the process of mutation variations are produced, and the
variations that prove 'better' at replication will become more common
and therefore have a greater chance at replication again. In memetics
the meme is mutated by its environment on a constant basis and changes
in an early form will accumulate and get passed on as they replicate.
In this way memetics behaves much more according to the Lamarckian view,
which pits it directly against the many who are devoted to proving that
genetic evolution does not function in a Lamarckian manner.
Would it then be possible for our Phumox-agent, with all its evolutionary
powers and ability to not only instigate a process but also to realise
what was actually happening, to propagate, mutate and disperse a few choice
memes? Maybe the act of viewing, participating in and discussing culture
is inherent in all artistic practice - whether it fancies itself as a
(pseudo)science or not. If memes are being generated by the audience viewing
a Phumox project are there any being generated amongst the other organic
participants? Do bacteria even do cultural transmission, or are they happy
enough just expressing their genes?

the phumoxian response
The initial response of the Phumox project involves an Artificial Intelligence
system designed by Brian Lee Yung Rowe called Generalized Cellular Signalling,
the theory of which is described below in his own words.
'On the surface, there doesn't seem to be much of a relationship between
bacteria and brains, though recent research on bacteria implies a profound
connection between the two, particularly when viewing bacteria as a collective.
Both are systems that consist of hundreds of billions of cells; both are
highly connected and can send multiple types of signals to other members
of the collective; both exhibit a number of emergent behaviour, including
intelligence. It is widely known that the brain is the source of intelligence
in humans, but to most people, the idea of intelligent bacteria is more
dubious than the idea of intelligent design. And yet, there are numerous
observable traits that point to collective intelligence, such as specialization
and cooperation within the colony and democratic voting. Given these parallels
between bacterial systems and neuronal systems, a number of questions
can be raised: 1) What exactly is intelligence? 2) Are bacteria the evolutionary
predecessor of brain systems? 3) What other parallels exist between these
systems and can we use one system to inform us about the other (and vice
versa)?'
The Generalized Cellular Signalling model is a platform for exploration
into emergent behaviour and intelligence using cellular systems. Within
GCS, a complete virtual environment exists where individual cells act
independently and can communicate with other cells either in a neural
fashion using relatively fixed connections, or bacterially, where signals
are propagated as molecules through a medium. GCS is inspired by two independent
paradigms, and like the systems it models, is (hopefully) greater than
the sum of its parts.The basic process of early Phumox works is to implement
GCS at some point in a distributed natural system and for it to take one
or more of the positions of observer, parasite, symbiont or collector
and broadcaster of memes. Any one of these activities can be a force for
evolutionary, physical or cultural change. The obvious relationship we
wish to explore is that between the GCS and living bacterial colonies,
to allow the two intelligences to learn about each other, to allow technology
to enter into dialog with bacteria on their own terms. We will be working
initially with cyanobacteria, species such as Anabaena, which already
have well established symbiotic relationships with aquatic plants and
are major players in complex ecological cycles. By inserting the GCS at
strategic points in bio-artificial ecosystems and allowing a give-and-take,
push-and-pull, listen-and-learn relationship to emerge with the bacteria
we will begin to gently influence symbiotic relationships to become more
parasitic and to push the bacteria to a point where their response is
to begin to naturally genetically modify themselves. As the environment
adapts to the GCS and its stimuli, we also look to the GCS to adapt to
the environment.
With the continuous introduction of the man-made, artificial and chimeric
into the natural environment and the gradual convergence of wetware, software
and hardware it is worthwhile to explore the adaptive reactions of ecosystems
and the possibility of new data types suggested by nature/machine interactions.
The work must provoke discussion about how new technologies are changing
the way both humans and nature live and evolve, and how many vital processes
that shape the world around us are adapting to accommodate new bioartificial
ecosystems. Through the discovery or evolution of novel forms of machine
and nature communication and examination of its inherent data and intelligence
we hope to facilitate new modes of approaching and understanding the techno-organic
environment. Phumox frames our interest in exploring connections between
machine and nature that are outside the typical areas covered by cybernetics
or purely scientific study whilst maintaining the ability to engage or
critique.
