Two evolutionary episodes

Michael Tomasello in his book, The Natural History of Human Morality argues with good data that humans are more cooperative and the simians more competitive, so how might we have evolved just so?  Here are two possibilities.  First here’s a story from the NYT on a group of chimpanzees who have moved from the forests to the savannah, from shady, cool environs with lots of fruit to sunny, hot grasslands where food is harder to come by:  Why the move? Perhaps their leaders had a yen for new, less crowded surrounds, sort like Daniel Boone or, as I have posted here periodically, those who settled the Andes or the Himalayas or the Artic. Perhaps they were a small group threatened by a larger and more belligerent group and so sought out safety in a place the others did not want.  The researchers gathered the chimps’ urine, no small undertaking in a hot, dry environment.  Even to get close enough to see them micturate and then collect the samples took 4 years of gentle contact so that the chimps became more comfortable with human presence. This is good, patient research. The urine showed that they were getting enough food but that their lives were stressful enough so that stress hormones were consistently elevated.

Now this is important because elevated stress hormones over the long haul can lead to health problems—the body and mind sort of wear out and grow thin with that load of stress.  Burn out we call it.  A sustainable life style would demand measures taken to lessen the stress, e.g., moving on, or behavioral change to cope with the conditions more effectively.  These chimps have changed their foraging behaviors to do more at night, avoiding the heat, though their species specific pattern is more activity in the daytime.  These chimps take a siesta during the heat of the day.  Of course at night more big predators may be about, so group communication becomes more important, as does having an escape plan. Then I thought about how we cooperative creatures cope with stress through social means, providing emotional support, increased creature contact, sharing the good stuff, etc., and I wondered about the genes promoting such behaviors increasing as the savannah chimps reproduce over the generations.  That is one episodic way we could have become more cooperative creatures.

The second episode comes from a new book I am reading, The Encultured Brain. I will say more about it later but now I want to cite a study of a baboon population reported therein. Baboon society is notably harsh by our standards; social order is based upon coercive and aggressive actions by the alphas.  A longitudinal study of one group, however, showed that after most of the alphas died in a virulent epidemic, the group now led by the non-alphas (betas?) became more peaceful and cooperative:  less fights, more grooming and sharing.  Further, new baboons that joined the group adapted their behaviors to this new ‘habitus’ and these changes have persisted over some years now.  I presume that the alphas were more susceptible to the disease for some reason (the heightened stress of leading by force? Like our type A behavior people die more from heart attacks, etc.) and the betas liked their way of interacting, having developed increased empathy from their lower position and perspective on the social scale.   A stretch there, I know, but a viable hypothesis nonetheless.

I read somewhere that the meek shall inherit the earth, and despite much data contrary to that, when I ponder these studies, I think maybe so.  Maybe so.  Travel on.


4th Anniversary #4: Some of my basic lessons

I look at what we humans do every day all day long in the course of living and see biological marvels. Over the course of these past four years I have learned some wonderful basic lessons. Some have come directly from my reading. I re-read Langer’s Feeling and Form to gain more insight into art and presentational symbols. I re-read her Mind, vol. 3, and understood more about two important dialectics. The first is within the individual between the need for reality orientation and the pleasure of unbounded symbolic creativity. The second is within society between its need for each member to commit resources for group maintenance and to carry traditions forward for continuity and the need for individuals to be creative and innovate to maintain social vitality.

I understood from Chris Hitchens the possibility of the natural noumenal, i.e., a noumenal realm filled with the shadowy ideals and mystic forms not in some supernatural domain but in this positivistic one. And of course, this past year I re-read Monod’s Chance and Necessity to find that the ethic of knowledge directs us to the natural spirit inherent in the descent of genetic forms evolved through countless random events beginning with the appearance of life on Gaia. Along with that I read Tomasello’s The Natural History of Human Morality that confirmed two ideas, that an ethic of knowledge leads to a knowledge of ethics and that our cultural values, while distinctive, are based upon some continuity with the rest of the animal world. Our humanity is indeed rooted in empathy and symbolization.

One of my evolving lessons comes from long efforts at understanding how our mind works. Since my first stint in graduate school in speech and language pathology in the mid 1970s, I had pondered the role of old and new information, beginning with hippocampal functioning but going on to how our brains define or create the categories and how they are transformed, i.e., old becomes new and new sometimes becomes old. Over the past four years I have realized that these processes are actually embedded in the larger functions producing variance and invariance. Remember William James’ characterization of consciousness as the “remembered present” or someone’s phrase the “specious present”. It takes some short passage of time before information from the retina or cochlea or skin reaches the brain and then is processed enough to be available for sentient awareness. (Another of my lessons is that I came to differentiate sentience as deriving from perceptual impact and consciousness as deriving from autogenic, i.e., self generated, information). Thus the information of which we are aware is necessarily old. New information comes about when we notice change; this is seen perhaps most importantly in hippocampal processing where change=new information (or sometimes no change violates expectations for change and that also equals new) which triggers theta processing, i.e., a new focus and situation is engendered. Along with this remember that recognition occurs when new information is ‘recognized’ as old and recall occurs when old information is ‘recalled’ as new, and that this is based on memory, i.e., past experience is held as an invariant form.

I have come to understand that variance/invariance is an extremely basic, even essential, concept for our understanding of life. I started down this trail upon reading a research article on the dual loop hypothesis of language. The loops are a dorsal one composed, I think, of cortical tracts that maintain primarily invariant information and a ventral one composed of cortical tracts involved in the processing of variant information. Consider the writing process or any example of verbal composition. Some invariant bits, e.g., words, are assembled according to syntactic rules to convey a new and variant message. This has always impressed me, that while we have formulaic speech for social purposes, e.g., “How about this weather?” most of our utterances are novel. While maybe the sentence’s propositional form follows an old/new pattern in subject/predicate or topic/comment, this serves the basic ongoing hippocampal processes of contextual generation of usefully defined situations, which for linguistic performances, must be a relatively rapid process in order to facilitate the intentional guidance of expression.

But variant/invariant can operate independently of temporal parameters, e.g., old/new, and so is important for our mental displacement of information divorced from current time and space. This seems to me now to be yet another manifestation of the basic biological processes underlying life. As we humans have extended our knowledge by understanding larger and smaller scales, e.g., cosmic and quantum, we again come around to Herodotus’ dictum that you can never step into the same river twice. Change and flux seems to be the basic order of the universe as it runs down to some entropic end. Life’s vital processes hold this procession in abeyance, the soma a protected environment where flux is background noise. We have come to understand that life is defined by our genes holding still as invariant forms, albeit with important random and rare mutations, replicating through generations. Thus Monod characterizes the forms of molecular biology as irregular crystals. That our minds operate to hold information in invariant forms, e.g., memory, is only another version of that tale.

Monod starts his book giving us the source of his title from Democritus, “Everything existing in the universe is the fruit of chance and necessity.” This from the man who around 400 BCE understood that atoms were a basic element of our universe. Monod found that evolution proceeds through chance or random events but that once a new gene passed two challenges, fitting into the coherent whole of the genome and then promoting adaptability of the organism, the new structure continues by necessity. Our brains and MEMBRAINs carry that feature through our mentality. Life in essence operates to mitigate exigencies and to exploit opportunities. No surprise that our minds do the same. Consider this example from current events: once we form an opinion we tend to preserve it despite new contradictory information. Invariance is naturally a conservative process. Cultural orthodoxy, especially religious, maintains invariance; rebellious hereterodoxy promotes variance until it succeeds in transforming views. The beauty of science lies in how it handles errors, i.e., variance, in its practice and theory and in how it institutionalizes the disjunction between our conceptual world, i.e., the doxa, and reality or nature, thereby making the empirical process necessary for objective and reliable understanding, so the need for our ethic of knowledge.

As I have studied our roots, some questions have come unanswered. What was the chemical process initiating life? How did sexual reproduction start and take hold? What were the genetic springs that fed the streams leading to humanity? Were the dominant ones for empathic and cooperative relationships or ones for control of displaced information? Are our distinctive mental faculties based upon cognitive advances, i.e., the orthodoxy, or are these advances really to serve a remarkable blossoming of empathy, i.e., heterodoxy? How is the self composed from the soma, its brain and the MEMBRAIN? Why were some of the earliest artworks hidden deeply within caves? What led to our awareness of a noumenal domain and then to its reification as supernatural? And how is it so much ugliness is tolerated by a species that developed such a keen sense of aesthetics?

In the course of writing these anniversary posts I realized more explicitly than I had previously why I have always written “soma, its brain and the MEMBRAIN.” While the MEMBRAIN understood simply and basically as an exaptation of the brain, the MEMBRAIN is strictly speaking not of the soma or its brain. It is rather a construction based solely on social interaction; it is necessarily a social organ embodied in many conspecific somas. It comprises the self of social individuation based upon attachment and socialization and not just the self of agency and autobiography. It comprises the self as presented socially through various roles as well as the self hidden behind those presentations. Of paramount importance it comprises the self’s adoption of the habitus, the cultural mores and practices that knit the social organism together.

One final lesson for me from me: the dialectic between positivism and mysticism that operates as my mind finds its way to understanding. In these posts I have focused more on the former and now I will conclude with the latter. The ancient Greeks thought that the universe was composed of 4 elements: water, fire, air, and earth, and this conceptualization served them well for a time. Before I travel on, here is a scientifically transformed elemental prayer.

Elemental Prayer

Let me hold this water I use today

Remembering its earthly passages

And wondering how it came here.

Let me burn this energy I use today

Remembering its finitude between earth and sun

And wondering at its myriad forms.

Let me breathe this air I use today

Remembering that I am a human

And wondering how the fire burns within.

Let me walk this path I find today

Remembering those here and passed

And wondering at Gaia’s kindness.

Review: The Natural History of Human Morality

Our gardens are taking much of my energy these days, but I sometimes reflect on my biological preoccupations while I am out there. For example, why am I currently focused on the biological roots of human values? Two main reasons. First, I live in an area where strong fundamentalist, even evangelical, religion fills people’s minds and our media. Associated with that comes a nostalgia for the Confederacy. I often read locally that god (take your pick of the many iterations out there) is the source of values, so our American separation of church and state is misguided. Oh, so wrong, even looking at the beliefs of our founding fathers (and mothers). Plus, I have just finished a magnificent book, The Half Has Never Been Told, about how our capitalist and wealthy society rose up on the backs of slaves, and that was a value preached from the white pulpit. Values are man-made, so to speak, and biological in origin even when they are perverse and distorted.

Second, for a rational source of values, go back a few posts (6/28/17 & 7/8/17) where I reveled in Monod’s exposition of spirit conceived of as inherent in our biology. I find his thinking a clear guide to true and humane values, so back to Monod’s ethic of knowledge and the knowledge of ethics. The basic biological value is to promote the generational advancement of a species, i.e., replication of genes and the evolutionary descent from life’s inception until now. All life is local and flows into the future as best it can. If you have followed my blog over the past year or so, you know my supposition that life’s basic task, then, is SWP (Solving World Problems), i.e., the job of gaining what is needed from the world to fulfill that basic biological value, and SWP engenders the ethic of knowledge. The better we know the world, the better we can SWP. You also know that early on in Gaia’s evolution sexual reproduction appeared and that increased the force with which life flows into the future because it increases the pace of new genetic combinations and most significantly for our humanity, it engendered a new set of values for CR (Conspecific Relations). CR transformed the biosphere with the advent of mammals and their remarkable evolution of family relations and empathy. Finally you know that very recently in Gaia’s past SWP embraced CR as a way of organizing the group for success and CR embraced SWP as a way of developing more powerful actions together. In more concrete terms conspecifics became adept at learning and cooperating with each other to mitigate exigencies and exploit opportunities, thereby increasing survival rates, and also turned their impulses to SWP to focus on group organization and governance. That, for me, is a decent summary of the evolutionary descent of humans as we developed a cultural world and an awareness of our humanity.

Many values develop from there, and I appreciate Michael Tomasello’s book, The Natural History of Human Morality, for illuminating this important phase of our evolution. His basic method is to compare empirical studies of moral actions between simians and toddlers, reasoning that any differences shown thereby through similar or analogous designs would highlight the evolution of human morality as distinct from that of apes and as independent of cultural entrainment, i.e., the toddlers would not show much effect of acculturation because of their age and development so any differences could be seen more surely as our evolutionary genetic heritage. Simple and brilliant. And he cites a good deal of research showing some distinct and important differences.

The basic difference is that apes are more competitive than cooperative while toddlers are more cooperative than competitive. Simians will cooperate in order to win a competition, perhaps against one stronger because their social order and interaction are based upon force to a large degree. (If I remember correctly I think Frans der Waal reports some simian relationships are also based upon age, history of interaction, family relations, what I might call simian social wiles and empathy so Tomasello may be overselling the simians’ lack of caring.)  Tomasello does look at some distinct differences to be seen between young humans and mature simians and these highlight the reliance on force used by the great apes in varying degrees, bonobos less than chimps, in contrast with the care and comfort offered by human infants, social behaviors not seen in the simians. For example, human infants as young as 14 months will help others, even strangers, when they perceive their frustration at a task by doing some action to solve the challenge to the goal. They will help spontaneously without incentive. Likewise, they will comfort others who are distressed; the higher the level of distress, the more likely the toddlers respond to soothe. They also show satisfaction when another person provides the soothing, and this seems to me clear indication of the mirroring system establishing a loop of a right brain leading with the warm social reaction to a vicariously experienced social situation. Whoa! These sorts of behaviors are by and large absent in the simian repertoire.

Tomasello goes further and argues that human morality is thus shown to be distinctive very early on, and that argues for a strong genetic influence. He then incorporates more observations as he explicates how our morality changes from our early empathy guided behaviors to the more sophisticated mores established through acculturation. This early empathy (my term, not his) provides the substrate upon which self-other equivalence is developed, and from there the next step to self-other morality, i.e., the same rules apply to each, is tangibly realized. Here, if you will, is the biological origin of the golden rule: do to others as you want done to you.

Part of this shift in human development involves the widening of the empathic circle to include non-kin and even strangers and this comes along with our cooperating with just about anyone really to do necessary tasks, tasks that cannot be performed without competent cooperation and that are important to the selves and their group(s). Herein grows the expectation and obligation that everyone is expected to perform competently in attaining their goal and the same rewards and penalties apply to everyone. These social mores develop incidentally, more or less, until their codification and increasing social complexity demand conscious consideration. Tomasello explains this in some detail and brings up an idea from his earlier work, that these new ways of interacting brought about new ways of thinking. I am still considering how to understand what he means there and so will post on that later, I hope, and I have purchased his earlier book, The Natural History of Human Thinking.

I find much support in this book for my notion that the evolution of empathy and symbolization form the roots of our humanity. I especially appreciate the good science in demonstrating how our empathy is different from that of other animals and how that has led to a moral dimension of culture. Our empathy is indeed very powerful and pervades all of our mental development. Our special sense or intuition of another’s intent and mental states/processes allow a grand expansion of cooperation, especially as this also leads to symbolic communication about our subjective experience, thoughts and feelings. (Remember, sometimes empathy+symbolization=art.)

I also find some clues about how to understand phenomena like slavery or its modern incarnations in the ways the rich steal the fruits of working people’s labors. The enslavers and the powerful wealthy elite operate with a morality more akin to the simian’s reliance on force: if I can gain resources from the community for myself by force and manipulation of law (and values), ignoring the empathic connection so strong in humanity, I am successful and dominant. The next time you see an ‘alpha’ male gloating over power and wealth, picture a simple ape standing over his pile of bananas while others look on empty-handed and wonder how some can depreciate our distinctive values arising from our biology. Finally, consider how the cultural mind-set of power, e.g., colonial imperialism, is so prominent in some nations and classes and resistant to change (talk to a Scotsman about the English, talk to the 99%ers about the 1%, read Piketty’s Capital in the 21st Century, listen to Noam Chomsky).

I learned a good deal from this book and will learn more by re-reading some passages and maybe one day soon (like winter time when the garden lies mostly fallow) I will re-read the entirety. That said, I want to recommend this book with a quibble: the prose is academic and at times oh so tedious. I understand the academic culture and social styles; I struggled with writing in accordance through two graduate degrees. I got better with the help of my excellent advisers, who, I am sure, found my natural style very un-academic and prone to ambiguity, obtuseness and metaphorical extension. Kind of like here. So read this book patiently, being forewarned of potential difficulty, and consider what this means about us humans in the grand scheme of life.
