octobrains



Did the 100s of smelling, tasting, feeling suckers on the 8 legs of an octopus do a similar thing for the octopus brain as the evolution of hands did to ours  ?... and did the decentralised architecture of the octopus brain reduce the impact the 8 arm rich information stream had on evolving a complex central brain?

Or was it that without the single repeated architecture of the mammalian neocortex as general intelligence engine, gains made in complexity in those sensory streams were not as reusable toward the evolution of a more general intelligence ??

mr robot guess #254


The world is simulation. The Facility has detected existence of the real world - one level up from the sim. Mr Robot is not Elliot’s father, but from one level up - and runs as an instance in Elliot’s brain from time to time — sometimes sharing.
...
Naah . I withdraw this guess - It doesn't account for the time trickery ... possibly.

take the lead and run with it

how funny would it be if all the lunacy of colonialism was a result of lead plumbing for the aristocracy . NOT

lead is a neurotoxin with evidence showing loss of executive discretion, btw
...

but of course lead doesn't quite so neatly explain all the current day pathologies
....
except for maybe by ... sheer inertia

....
like if you inherit a system with lunatic aggression providing you all sorts of crazy power, a understandable reaction might be to simply continue in that vein.

'run with it'

Take the lead and run with it - a lunatic theory for the early anthropocene

gene and race

So there was this discussion on non-racialism at this book launch last night ...
and a member of the audience asked that typical question about the obvious genetic basis to race.

I was working up to try and answer there, but found it a bit hard to get my thoughts together in time. So below is working toward how I'd like to answer that in future. I'll correct/refine it with time, hopefully, and corrections and comments from you, the anonymous or not anonymous public, are as welcome as always.


 Attempt One:

Once our very early, singular human population separated geographically (after what appears to be a series of survival bottlenecks), they evolved separate and particular traits according to the now well understood processes of natural selection and genetic drift. 

Even while populations were largely separated, there was still sufficient movement and interaction to allow for genetic information to pass between populations. This, most importantly, would have included the successful spread of immune response adaptations and anti-parasite counter-measures vital to early population survival. [which is why all so called races have within their populations a spread of proteomic pathways for immune function that are common between races] 

As populations interacted and genetic information spread, there are a few mechanisms by which certain traits persisted within local populations, despite the relatively thorough statistical mixing of other genetic traits. The  mechanisms that ‘preserved’ local ‘race type traits’ include environment specific adaptations (like skin colour) that were continuously selected for within separated populations by survival pressure, and culture-specific sexual selection criteria - that proceeded along with cultural evolution. There are more mechanisms i think, but these two come to mind for now.

Via these mechanisms, an aggregation of certain traits (the sexual selection model accounts for why these are most often just externally visible) would accumulate within populations, while allowing the fortunate mixing of other vital genetic survival strategies without which local populations would most likely have fallen from parasite/pathogen load/stress.

This explains why, with the exception of this small percentage of ‘race type traits’, when looking at particular sequences, we often see more genetic diversity within races than between them — for example, there will be a particular immune system function that is expressed in different ways by several different protein pathways (lets call them A,B,C,D) and each race will have individuals carrying sequences for A,B,C,D. For the larger pathways, two individuals from different ‘races’ carrying the sequences necessary for A will often have more in common genetically with each other than with members of the same race carrying sequences for B, say.

[Immune function has been a big driver for evolution throughout the entire animal line, and so its not for nothing that it gets emphasised when discussing genetic variation.]

Even as our populations experienced civilisational shifts that allowed for more interaction between populations and more and more geographical displacement, patterns of mechanisms like the culture-specific sexual selection mentioned above - now intimately coupled with power, violence, etc. - still worked to keep certain traits prominent within local populations. 

Anyway, I think that's the type of traits the dude from yesterday mentioned. That small percentage of genetic traits, often highly visible, that we based the myth of race on.


 added later:

Of course, the other reason that immune system is so important when discussing us, is that in the very brief evolutionary time since we split up, nothing much else changed.

Sure some of us lightened our skins and straightened our hair, but these were almost insignificant changes when seen against our vast evolutionary history.

The most significant changes to humankind since our ‘forking’ is that the big brains that we evolved before we split led to us being super successful wherever we went - and that success was met in turn by a multitude of parasites rushing in to live off a newly found ecosystem - us.

So, most of our real evolution as humans, neglecting the very very minor surface tweaks, have been in complex immune system responses to those parasites since we became successful. That is why we are closer to members of other races that share our immune pathways than those of our race that don’t - immune system complexity makes up most of our evolution since we got here.

Are We Shifting to a New Post-Capitalist Value Regime?


RT @mbauwens (Michel Bauwens): Are We Shifting to a New Post-Capitalist Value Regime? https://t.co/l1tn1LEs0R (one of my best lectures)
"We will argue that there is consistent evidence that the structural crises of the dominant political economy is leading to responses that are prefigurative of a new value regime, of which the seed forms can be clearly discerned."

race and inequality links flow both ways

Racism is also emergent en-masse because it allows a population to subconsciously rationalise their privilege. So instead of just causing social injustice, racism is also a result of social injustice. The more you see racially implemented social privilege, the more you have to apply racist models to subconsciously justify that privilege - when you have it.
