In the previous post we introduced the idea that indifference was the primary action at work at the biochemical and cellular levels.

At this level, it would be hard to express any survival strategy beyond probabilistic, since reproduction is asexual with those cells that have the proper attributes, being able to dominate an environment in a short period of time. Similarly, it is also an environment that is subject to genetic “plagiarism” whereby novel combinations or sources of genetic information may be acquired directly through mechanisms like conjugation. The process of conjugation results in the transfer of genetic materials from a donor cell to that of the recipient.

Even at this rudimentary level one would be hard pressed to argue that there is any real competition beyond that of indifference to the survival of other cells. They certainly aren’t engaged in battling each other directly, so there must be a fundamental principle at work even at this basic level that needs to be considered.

The basic principle can be described as “competition may be difficult, but fighting is expensive”. Therefore one of the governing principles of biology is that fighting should be avoided at all costs. While acquiring resources may be quite competitive, fighting shifts that focus to a significantly higher risk activity and prevents the accumulation of resources. Therefore those members of a species that are able to behave more “indifferently” to others can retain their focus, while those that fight will either be killed, injured, or deprived of resources that others obtained in their distraction.

It is this distinction that gives rise to one of the points often misunderstood regarding “survival of the fittest”. The base interpretation has often been one of bloodied conflict or aggression, when in reality success is primarily based on tolerance and indifference precisely to avoid these higher risks. It should also be noted that fighting is not reflective of the predator/prey relationships that may exist and shouldn’t be confused with that special case.

While our current set of examples doesn’t specifically suggest cooperation, it paves the way for such development, since the alternatives tend to result in higher risks with questionable benefits. Therefore while the behavior is certainly self-interested, it would not rise to the level of being strongly selfish where the potential for more aggressive encounters could occur.

From this point we see two paths of increased cooperation developing. When we consider the reproduction of single-celled organisms, the cells in the immediate vicinity would share a common heritage since they would possess the same genetic material. In addition, this common origin would suggest that there might be enough of a chemical basis to form a cohesive group that could exchange chemical information without compromising the integrity of any individual cell in that group. In other words, this could be the origins of a primitive multi-cellular or colonial organism.

The second point is that methods like conjugation could be made more orderly if specific groups of cells could exchange genetic information with similar groups. This would result in an equal exchange of genetic information and provide potential benefit to both groups. At this point, the groups become locked into a “cooperative” agreement for reproductive stability and the beginnings of sexual (versus asexual) reproduction would occur .

From this, various species have adopted a wide range of mating strategies, but at some level, they must all cooperate to some degree or another. The only possible exception that comes to mind is the hostile nature of many insect reproductive methods, which I will attempt to address later.

Without retracing every evolutionary step, the benefits to multicellular organisms extended their mobility, afforded new methods for protecting themselves, and gave rise to many novel and specialized developments as a result of this new cooperative effort by the individual cells. Once again, it is useful to point out that, even at the cellular level the primary processes are governed by “indifference”. It would be difficult to argue that cells have a preference in being a muscle cell versus a skin cell, or a neuron. As a result, each is “assigned” a responsibility and benefits by the success of the group. Failure to cooperate invariably endangers the group and gives rise to cancers and other destructive variants.

In addition, this grouping of cells would have a unique chemical signature with which it could identify members of the group and anything that differed would be treated as a threat. This is where the immune system would come into play and why the response to disease and even transplanted organs originates. In this case, cooperation has not only extended the scope over which an organism can operate but also provided a strong “incentive” to be a part of the group versus going it alone.

These developments gave rise to new levels of competition but not necessarily confrontation. While each species will do its utmost to acquire the resources it needs to survive and reproduce, it will rarely manifest as direct confrontations. The notable exception to this is when a species itself becomes the resource.

So if we consider the more stable each step is, the greater the possibility and need of novel approaches becomes. In our scenario, once single-celled organisms had dominated the available niches and maximized the means of exploiting their environment, then new variations could extend that influence and increase the number of solutions for more diverse ways of acquiring resources.

NOTE: Bear in mind that resources would consist of raw materials from the environment, or the species that acquired those resources. Therefore the driving force in all development was to either become better at directly acquiring resources, or to become better at acquiring the species that contain those resources. In both cases, this created an absolute dependence in the balance between all the competing species to avoid total depletion and consequent death. Therefore, the selection pressures on any species were always oriented towards improving their exploitation, but not becoming too efficient since both would result in their demise. It is these selection pressures that ultimately played into the reproductive rates, so that a species would reproduce at a rate that was commensurate with its necessary representation in the environment. Since this is a quite delicate balance to achieve, any major variations will tend to result in species extinction.

Gerhard: that old 'nature red in tooth and claw' cliche is well past its prime, and its about time it was replaced with a more accurate picture of natural evolution.  Nature indifferent to the survival of the biological individual is nearer the truth.

I would think that a sated predator would be indifferent to the near presence of potential prey, and a prey might evolve the 'cleverness' to feed near a sated predator and thus gain an advantage over species that could not differentiate a hungry predator from a sated one.

That' s my only thought for now.  It's way past my bed-time.  (4:35 am UK time).

I look forward to reading more of your ideas.

Excellent coverage of the issues Gerhard. Therefore while the behavior is certainly self-interested, it would not rise to the level of being strongly selfish... And this point illustrates nicely the dangers of excessive reductionism. When normal assertiveness necessary for survival is pushed under the umbrella of selfishness, it will inevitably be confused with selfishness, then the chances are that you'll end up in a mire, something like, well,...selfish gene theory.

Which is a whole new squirm of vermians.
Thanks, Steve.  I've been looking for a chance to use that expression.  I think Darwin would have enjoyed it.

Steve, there's no question about it.  The irony of it is that if one examines the role of bacterial conjugation (where genetic material is exchanged), this is a mechanism whereby where there is no equitable distribution of genetic materials.  Therefore if such a thing as a "selfish gene" existed, then this would have been the preferred evolutionary path to ensure its survival.  Everything after that has reduced the chances of a particular gene's survival (whether it be sharing the genetic material with a sexual partner, or producing vast numbers of offspring in the hopes that one or two survive).

None of those strategies are particularly agreeable to the objective of maximizing a particular gene's chances, but rather they are strategies that ensure survival of the "group" of genes by cooperation and even sacrifice.

logicman's picture
Gerhard: another point about bacteria.  If they truly had selfish genes they would have wiped out us humans long before we had a chance to invent the microscope and discover antibiotics.  Instead of wiping us out, most of them became allies of animals as intestinal microflora.  How wonderfully altruistic of them!

Gerhard Adam's picture
Actually that makes a good point, since it seems that what may begin as a parasitic relationship can ultimately become fully cooperative in symbiosis.  To be honest, it is very difficult to find any instances that seem purely selfish (at almost any level).  More to the point, I find that often the discussion of competition is misleading because it is applied too broadly and to too many different situations.

In fact, it creates the illusion that animals are in a perpetual state of high alert and must forever be exercising their "olympian" objectives for the "gold".

Gerhard: if it helps - Most words based on behaviour or activity - the 'doing word' nouns - have an active and a passive semantic component.  Competiton may be active or passive.  Think of economics in the modern world.  Producers in countries A and B compete to sell similar goods in country C.  The producers in A and B, the real people involved, are unlikely to come to physical blows.  If they were unaware of the existence of competition as an emergent property of the market, i.e. only each aware of their own marketing, then the competition would be entirely passive.  The two producers would be 'perfectly indifferent' to each other.

Compare that economic passivity to animals drinking or feeding at the same location, but different times.  They are in economic competition for a resource but possibly remain entirely unaware of each other.  Game theory is fine, but it requires knowledge of an opponent's existence.

Gerhard Adam's picture
Thanks Patrick.  It very much helps, since part of a future post addresses this whole business of competition.  In particular, trying to differentiate between the kind of passive competition you're describing, the extreme competition during critical shortages, and the competition within groups.  Not to mention the other usage which invariably introduces the predator/prey situation which tends to confuse the other issues as well.

I think this sort of perspective is singularly lacking in economic or political discussions. People talk about "greedy bankers", "greedy supermarkets", etc., but these institutions exist in an environment where small sharks are eaten by big sharks.

There is no ground for the "chattering classes", as we call them in Britain, to think "we're the goodies, they're the baddies".  If I were a Hedgehog from outer space, seeking a generic name for the newly-discovered human species, I think I would plump for

Autodikaiopithecus = "the self-righteous ape".



Gerhard Adam's picture
You're correct with that.  The problem with economics and politics, is that we have a central authority that can redirect resources and exhibit favoritism.  As a result, we truly don't have a free interaction as we would in biology (same thing occurs there with many managed environments).

The fundamental principle of evolution and natural selection is that something must invariably die if something more successful comes along.  It seems our current economic/political systems are intent on preserving, instead of letting them die when they need to.

Steve Davis's picture
The intestinal microflora case is interesting, as it shows the difference between parasitism and symbiosis. The net benefit in fitness for both parties is greater with symbiosis than with parasitism, yet the gene-centrics would have us believe they are one and the same.

Interesting alternate take on the import of group-living.

I think you do a good job in poking holes in social Darwinists - & for all the holes that've already been poked in them, they can always use some more - but I'm concerned that you're making their same mistake of generalizing from a biological/evolutionary process to how humans should act.

The larger mistake of social Darwinsim wasn't so much a mis-interpretation of evolution, it was mis-application of evolution's principles. It doesn't matter whether evolution was tooth-and-nail bloodshed or peace & love. Either way, you're making a large jump when you try to apply "fundamental principles" of evolution & biology to human nature. I see that you're being somewhat cautious about this sort of leap, but it's in the post's tone & implications. In the end, the virtues of cooperation - along with every other decent human characteristic - has very little to do with finding its fundamental principles in evolution & biology.

Gerhard Adam's picture
Kerrjac, another point to consider is that evolution isn't about deciding what "should" be, but rather it is intended to provide insights into what does happen.

Anything to do with social Darwinism, or social engineering is flawed for the onset because it presumes that all responses are predictable and will result in a particular outcome.  This is foolishly naive and has nothing to do with describing the evolutionary forces that result in cooperation and even altruism.

Gerhard Adam's picture
To be honest, I'm trying to specifically avoid human connotations at this point, because humans have the additional element of their intellect and intentions to add to this. 

Overall the point is simply that "indifference" is the primary force, while cooperation tends to arise from this (without implying any conscious effort).  In short, there is no way that social Darwinism should be inferred from any of this.
