You're Mr Off Topic.
My obsession of complexity science is entirely
on topic, the only reason you and others
can't see that fact is the science is
above your heads, you haven't any idea
what the science teaches.
Not one person in this ng has even
been able to answer a 101 question
such as defining the term complexity
or emergence yet laugh like hyenas
at every solid cite I post about it
without even reading the cite.
I wish the conversations around
here would stick to things like
relevant concepts and ideas, but
this ng has become little more
than a typical flame infested
pile of garbage.
But I keep trying to steer every
post back to science.
Would you care to discus how complexity
science has revolutionized evolutionary
thought?
I would. Would you care to discuss this
article?
COMPLEXITY THEORY TAKES EVOLUTION TO ANOTHER LEVEL
One hundred and ninety-nine years after Charles Darwin was born, and
149 years after he published On the Origin of Species, some scientists
say that the theory of evolution is due for a revision.
Not a religiously inspired revision – intelligent designers need not
apply. Nobody suggests that genetic mutation and natural selection
aren't responsible for the evolution of birds from reptiles or humans
from tree-swingers.
But a growing number of scientists do say that neo-Darwinian evolution
doesn't explain certain jumps in biological complexity: from
single-celled to multicellular organisms, from single organisms to
entire communities.
The jumps – saltations, in complexity parlance – appear to be non-linear
emergent phenomena, the result of networked interactions that produce
self-organization at ever higher levels. From this perspective,
Darwinian evolution is a mechanism of a higher universal law, perhaps
even a variant on the second law of thermodynamics.
I've got an article in the pipeline on the union of complexity theory
and evolutionary biology, and over the next few days will publish
outtakes from the interviews here. One interviewee was Carl Woese, a
titan of 20th century microbiology, who with colleague George Fox
reorganized the organismal kingdom from five branches to three.
Woese's experience with bacteria led him to look for an evolutionary
framework larger than that provided by Darwin and his intellectual
descendants. Bacteria – which may account for up to half of Earth's
biomass – swap genes without reproducing; with millions residing in a
teaspoon of seawater, Woese sees them in terms of networked communities
rather than individual cells, and interprets their evolutionary history
as driven by the non-linear self-organization that's now being studied
at all biological scales.
It's a rough analogy, but if you knew a lot about individual stars, it's
doubtful you could predict the existence of galaxies. When the larger
unit is sufficiently integrated, the individual unit is not as
individualistic as you think. [...]
The prokaryote concept is a bunch of crap, and stood in the way of the
development of microbiology for 80 years. Only now is microbiology
emerging, and people like you can hear what I'm saying. These concepts
are not based on the individual organism, the individual species. The
individual unit in microbiology is not the cell; the primary unit is the
organismal community. Cells develop in organismal community; they don't
give rise to them; the evolution of the cell takes place in the
framework of this community. The individual organism more tightly
coupled to the whole than we recognized. [...]
The world of animals and plants began with eukaryotic cells, as you
know; what the history of the development of the eukaryotic cell is, I
don't know, but it's clearly a more complex entity than either the
archaea or the bacteria. There's something we're going to find about the
eukaryote that's very special, and captures the essence [of emergence
and complexity at the heart of evolution.] [...]
Evolution is a process that manifests itself at a level-independent way.
You've got these basic cells, viruses along with them – and then the
multicellular world, the same evolutionary scenario played out, but the
dynamics are shown to be the same; then you go to society and see the
same dynamic playing out again – but it's not the darwinian dynamic.
It's the pre-Darwinian dynamic, when individuality had little
significance, and everything was in distributed interaction. [...]
Saltations are state changes. The simple example would be something like
a magnet heated up to a high temperature where the iron dissolves;
the magnetic properties are gone; then when you reach a critical
temperature in cooling down, the magneticism reappears in a very short
temperature change.
The property is gone in the individual iron atoms, but when they behave
collectively, you see the property of the whole. That's a very simple
example.
The microbial world is where I work; [saltational evolution] predicts
that there should be properties of the collective thing, that arise as
the thing collects. [...]
Twentieth century biology was structured according to a linear
Newtonian worldview. Linear thinking is not the kind of thinking that's
needed to study evolution. It doesn't help you understand the nature of
systems. Molecular biologists were so set about linearity that when the
gene came along, they took the gene to be the be-all and end-all of
basic biology. That comes out of thinking in terms of particles and
linear interactions.... I see evolution as the quintessential non-linear
dynamics problem.
It's heady stuff, and a lot of the hard science that Woese explained
didn't come out well enough in transcription to make sense here. To
understand him more completely I highly recommend reading "A New Biology
for a New Century," published in 2004 in
Microbiology and Molecular Biology Reviews. It's a visionary blend of
history and microbiology, and shows that Woese is that rarest of all
organisms: a brilliant scientist who can really write.
