Part 1. Metabolic Metaphysics


Organisms become harder to define when they extend their metabolisms through, and become dependent upon, one another.

"Lichens are also clearly metabolically integrated. The products of photosynthesis flow from bluegreen or green to the translucent partner. What is seldom realized is that in tight associations the metabolites flow in both directions. The animal or fungal partner also releases materials to the photosynthesizer. Symbioses are two-way exchanges. The kindness of strangers, the metabolic flow of gifts, makes them less strange and, ultimately, part of a single, co-dependent biological self."

— Lynn Margulis and Dorion Sagan

"Indeed the lower we go in the scale of being, the more necessary is geographical unity for that close interaction of individuals which constitutes society. Societies of the higher animals, of insects, of molecules, all possess geographical unity. A rock is nothing else than a society of molecules, indulging in every species of activity open to molecules. I draw attention to this lowly form of society in order to dispel the notion that social life is a peculiarity of the higher organisms. The contrary is the case. So far as survival value is concerned, a piece of rock, with its past history of some eight hundred millions of years, far outstrips the short span attained by any nation."

— Alfred North Whitehead
Symbolism: Its Meaning and Effect

A mutually beneficial relationship among organisms is called symbiosis.

The concept of symbiosis can blur the distinction between organisms and their environments. For example, if a plant requires the participation of an organism of a different type, a bee, say, to reproduce, then the bee is a part of the plant’s reproductive cycle. And if the bee requires the pollen from the plant to feed its larvae, then the plant participates in the bee’s reproductive cycle, and the organisms enjoy a symbiosis. The organism is the beeplant. To where the bee flies, the plant might extend its range. To where the plant’s seeds light, perhaps due to the intervention of a bird, a new beehive might be established. The bird further complicates the relationships. Symbiotic organisms extend one another's metabolisms and environmental selection pressures.

A lichen appears to be a single type of organism, but lichens are integrated symbiotic communities of bacteria and fungi.

An enzyme produced by a micro-organism that lives in the gut of the termite enables the insect to digest cellulose (wood fiber). According to a 2/25/2008 Boston Globe article, Of Microbes and Men, the human body, by mass, consists mostly of symbiotic bacteria—about 90 percent of a body's cells. This notion, the human microbiome, is a topic of ongoing research.

Researcher Anna Skalka, Director Emeritus, Institute for Cancer Research, Fox Chase Cancer Center, and colleagues estimate that at least 8 percent of the human genome is of viral origin. She is interviewed about the work on National Public Radio HERE. Symbiosis raises this question: When organisms cooperate for mutual benefit, whose metabolism is whose?

The ambiguities encountered when trying to distinguish organisms from one another is a problem for evolution theory, because the theory needs to define something discrete for nature to "select" from among her interwoven metabolic processes. Which is a discrete unit of evolutionary selection, a gene, a trait, an individual organism, a species? This "granularity problem" plagues the Darwinian model.


The ambiguities take a dramatic turn in the more complicated case of endosymbiosis. This situation occurs when varieties of unicellular organisms merge to form a new kind of cell, which, being a conglomerate of symbionts, has a more complicated structure than its formerly independent constituents. According to normal evolution theory, various species of bacteria, or prokaryotes, merged to create the more complex, eukaryotic, cells that make up the bodies of multicellular plants and animals. The notion that this is how complex cells arose, through a communal pooling of resources on the part of bacteria, was greeted with scorn when researcher Lynn Margulis proposed the idea in the 1960s. But she got in the last laugh. Endosymbiosis generally is accepted today by evolutionary theorists as the most plausible evolutionary path to eukaryotic cells.

"Hence one must always ask how the partners are integrated, if they are always integrated, and what environmental conditions influence their integration. To substitute these sorts of details of metabolite flow and gene-product transfer between intimate former strangers with neodarwinian terms like 'cooperation', 'cost',' or 'benefit' is absurd and exemplary of the fallacy of misplaced concreteness. Such terminology precludes real understanding of the inevitably rich and complex evolutionary past of the symbiotic world that made animals, plants, and their nucleated planetmates."

Although tightly coupled anabolic and catabolic subprocesses create the illusion that bodies are fundamentally discrete biological units, the metabolic process per se is the fundamental structuring pattern. Organism is a conceptual convenience that designates a relatively stable cross-section of overlapping interdependent metabolisms. Organisms make their ways among other organisms, making and breaking bonds of various kinds, forming new entities in their combinations and recombinations of metabolic interveavings.

Technology: Humankind's Extended Symbiont

Is the coral of the reef distinct from, or part of, the living organism, the polyp, that excretes the coral? Is the coral an artifact of polyp technology, a component of the polyp's physical environment, or the true skin of the polyp body? Can the reef's coral be part of the organism and itself not be living? If so, it suggests that an organism can have two parts, one possessed of livingness and one not, the two being interwoven in the body of the thing. But are the molecules themselves possessed of livingness? Are the iron atoms that ride along in the hemoglobin molecule that keeps humans alive, alive?

The concept of symbiosis can be abstracted further to include social behaviors, as forms of intraspecific symbiosis. Microbiologist Bonnie Bassler describes symbiotic/social behaviors among bacteria and the chemical signaling involved to keep their societies thriving.


Something as intuitively nonliving as atoms of iron turn out to be essential to the lives of certain organisms, but it seems doubtful that any iron atom distinguishes between participating in living processes and nonliving ones. During its lifetime an iron atom will make and break bonds with countless other atoms, in hemoglobin molecules and rusty nails. Matter and energy exchanges within nature crisscross back and forth between the organic and the inorganic, seamlessly. Nature seems uninterested in maintaining walls of separation between the two domains. This observation raises questions about the character of manufactured (organic and inorganic) artifacts and humankind's relationships with them.

The Star Larvae Hypothesis:

Stars constitute a genus of organism. The stellar life cycle includes a larval phase. Biological life constitutes the larval phase of the stellar life cycle.

Elaboration: The hypothesis presents a teleological model of nature, in which
