The four mechanisms of evolution

Regular readers of the blog will know of my enthusiasm for evolutionary and developmental theories especially the eight stage evo-devo theory.

I have also advocated the four primary problems faced by all creatures undergoing evolution, as delineated by Theodore Millon- the problems of Existence; Adaptation; Replication and Abstraction which lead to polarities of pain/pleasure;  active/passive; self/other and broad/narrow at each of the stages/domains/ solutions.

However, when we pause to look at what the mechanism of evolution actually is, we clearly note that there are a few prerequisites for evolution to take place and unless all the four mechanisms/ preconditions are present it is unlikely that the creatures will evolve.   I have been having this in the back of my mind for quite some time especially as I  have been ruminating on the BVSR (blind variation and selective retention)  theory of Donald Campbell as applied to creativity.

I was recently reading ‘Driven’ and in that book too a lot of emphasis is placed on the V-S-R (Variation, Selection, Retention) mechanism of evolution. I think this popular portrayal of evolution misses another important ingredient required for evolution that of Struggle due to limited resources and excess fecundity. If the problem of limited resources and excess fecundity was not there, probably there would be no pressure to evolve.

 

Thus I would like to frame the four evolutionary prerequisites/ mechanisms as Struggle-Retention- Variation-Selection or S_R_V_S.  To elaborate:

1. Struggle: This is driven by the fact of limited resources and overproduction due to excess fecundity. Here two strategies, leading to 2 polarities,  work; one can either compete for resources or one can cooperate and exist symbiotically.  Also, one can either have a r-strategy (low investment in many) of reproduction or A K-strategy (high investment in few). In the eight stage model, the organisms at first 2 levels would be primarily constrained by this evolutionary mechanisms.

2. Retention:  There must exist some mechanism by which the traits that confer survival/reproductive or selection advantage can be retained over time in the same individual and over generations in the same species. Again the mechanism of stable trait over time as well as  over generations may be in conflict with each other and may lead to a polarity. Creatures at stage 3 and 4 of 8 stage evo-devo theory would likely face issues regarding stability and retention of traits; retaining in individual the same trait is an active process; while retaining in generations is more passively driven.

3. Variation. There must exist some  mechanism that causes minor changes in the stable traits such that variation may lead to deleterious or beneficial effect over the individual having that variation. This is classically implemented using mutations and sexual-recombinations. While mutations confer (dis)advantages at an individual level; recombinations take that to the next level by affecting offsprings variability. The creatures at stages 5 and 6 of evo-devo stages are grappling with these problems of adequate variation in self and other.

4. Selection: There must exist some selection criteria based on which the struggling creatures having stable but slightly varying traits can be selected for or against.  While Natural selection (stage 7) employs the three methods of directional, stabilizing and disruptive selection; the stage 8 deploys a qualitatively different method of sexual selection where the criteria for selection may be  arbitrarily driven by choices of the other gender conspesifics.  While the Natural selection criteria is broad, the sexual selection criteria can be said to be narrow. Another way to look at this is that the selection crteria is either to survive (natural selction) or to reproduce (sexual slection) and those who are sucessful can very well move from one level/species to another (speciation due to sexual selection).

To me this is further  corrobrating evidence of the eight stage evo-devo theory and ABCD model being on the right track.

Basic Emotions

Facial emotions.

Image via Wikipedia

This post is an attempt to get to the basic emotions. Regular readers of this blog will readily appreciate when I claim that there are eight basic emotions and that they follow a developmental/evolutionary time-course and follow a  particular order.

 

First let us review the attempts made till now to classify and identify the basic emotions- foremost amongst them is the tradition of Tomkins and Ekman that looked at basic and universal emotional facial expressions to come up with their list of basic emotions.

 

Tomkins listed the following as basic emotions: Anger, interest, contempt, disgust, distress, fear, joy, shame, surprise;

I agree more or less with the list except for dropping shame or subsuming it under contempt (along with say guilt too making a triad of social emotions)

Ekman on the other hand thought that only Anger, Disgust, Fear, Happiness, Sadness and Surprise were basic based on clearly identifiable facial expressions. He left out contempt and Interest , but I am not too sympathetic to that position, though I understand that being evolutionarily novel these would be least permanently identifiable using fixed facial expressions.

Another towering figure in the emotion research is Plutchick and his wheel is a wonderful figure that not only lists the basic emotions but also highlights the relations between them- which are opposed (180 degree to each other).

The 8 basic emotions Plutchik lists are Trust(Acceptance), anger, anticipation (interest) , disgust, joy, fear, sadness, surprise .

Astute readers will note that the list is more or less same as that of Tomkins except for substitution of Trust )(acceptance) for contempt (reverse scored but same?)

Izards list viz Anger, contempt, disgust, distress, fear, guilt, interest, joy, shame, surprise is also the same as above list if we group contempt/shame/guilt together as one social emotion category.

That finally brings me to my list and ordering and how the emotions are opposed to each other on some aspect or the other, here I would like to utilize some terminology from astrology where not only opposed (180 degrees) are bad or disharmonious but even squares (90 degrees ) are somewhat disharmonious.

with that lets take a look at Plutchiks wheel and order emotions as follows:
1. Fear
2. Joy/happiness
3. Anger
4. Sadness
5. Disgust
6. Surprise
7. Contempt
8. Interest (anticipation)

One would note that on Plutchik’s wheel Fear is opposed to Anger; Happiness to Sadness; Disgust to Trust (contempt in our scheme) and Surprise to Interest.

what I will argue is that while on one intuitive level Sadness is opposed to happiness and fear to anger on a deeper level the square relation between fear and happiness is more important and similarly between anger and sadness is more important; rather I would go ahead and claim that if I had to fit them on a wheel I would have fitted them as opposites instead of squares.

why the above claim; read this post for some background, but basically my claim is that these opposed pairs follow the opposed polarities of four tasks of existence, adaptation, replication and abstraction as outlined by Theodore Millon and also the eight basic adaptive problems faced by all animals. .

To elaborate, on their opposed natures, consider the first problem of arrival of a stimuli /something/some person; now this (con-specific/ other species animal) could be either predator or prey and thus arouse either feelings of Fear or Happiness depending on whether the arrival is viewed disfavorably or favroably- as foe or as food.

Consider second, the loss (departure) of a stimuli/ something/ some person. This can either arouse feelings of anger to restore the earlier status-qua or lead to feelings of sadness if nothing can be done and this is inevitable/ unavoidable.

Now consider a novel stimuli/person/thing introduced in the environment. This can either lead to disgust reaction if intuitively it is appraised that the stimuli in question is not good for self; or the stimuli/person/thing may arouse feelings of surprise if a positive outcome is anticipated nonetheless the stimuli being novel/ unexpected. when a new person mates another that person can be seen as a constant source of surprises.

Lastly consider a familiar or expected stimuli being present in the environment; this can either lead to contempt reaction as we all know that familiarity breeds contempt; or we could still remain engaged with that and still pay attention and be interested in that familiar stimuli/person/ thing.

This also squarely fits with my earlier basic emotions post based on work by Jaak Panksepp. There the basic emotions (in the particular order that I imposed) were fear, seeking (or happiness) , anger, panic(distress) , lust (mapped to disgust they even rhyme:-) , care (mapped to Surprise) and play (mapped to contempt in new model) and lastly SELF mapped to Interest/anticipation.

Of course one can also readily see that happiness and sadness are opposed; but that misses the finer opposition and continuum on a single dimension of fear-happiness (anxiety-calmness scale) ; anger-sadness (mania-depression scale); disgust-surprise and contempt-interest (psychosis-autism scale).

To me the basic emotions and there ordering seems just perfect- and these are same set of emotions that I have also mapped to personality as enduring traits.something seems to be falling in place and I am most reasonably elated.

The ABCD of Psychology and Happiness

I’ve recently latched onto the ABCD model of psychological entities, where any psychological aspect is defined by following four features/dimensions: Affect( how does it subjectively feel) , Behavior (what are the manifest effects resulting in overt behavioral changes) , Cognition (how is it cognitively appraised) and Desire/Drive(what are the underlying motivations).

I was prompted on this journey by the evolutionary theory of personality (see here) by Theodore Millon, where he identifies four different evolutionarily salient domains and fields of adaptation: Existence (pain/pleasure) mapped to Affect in my model, Adaptation(active/passive) mapped to Behavior in my model, Replication(Self-other) mapped to Desire/drive in my model and finally Abstraction (broad-narrow) mapped to Cognition in my model.

Thus personality clearly is a dynamic between these four ABCD factors. What we habitually feel, how we habitually act, what usually drives us and how we habitually make sense of our situations clearly defines a personality.

I have also covered how emotions can be similarly considered as belonging to these four domains and having four ABCD dimensions- affective in nature, lead to action tendencies, differential appraisal and cognitive underpinnings and different motivational states-whether the motivation to be in control or to nurture the other.

As it happens I am also keenly into this new ‘positive psychology’ stuff and keep reading the practitioners in this field; thus while reading ‘Happier’ I came across the happiness definition (as per Seligman) as anything that is pleasurable, meaningful and engaging, then I could immediately see the relationship to ABCD model by extending the concept of Drive (or intrinsic vs extrinsic motivation) to the mix and thus came up with this ABCD definition of happiness on twitter:

The above to me perfectly sums up the Happiness formula and is very easy to remember too!
I also serendipitously came across this amazing video based on Dan Pink‘s ‘Drive’

That made me think further of how the same ABCD formula applied to work incentives.

That to me is further proof of the simplicity and power of this simple ABCD formula. So are you ready to apply the ABCD of happiness and work incentives to your life?
