Sapolsky (egads part 2)

"Egads!" A more qualified voice 
has been found to elaborate on
the tiny bit of 
mentioned last time unit.

Aside from being an all-around awesome scientist/writer
Robert Sapolsky (paired with Stanford University) 
has brought his 

As if there were not already 
enough things to admire 
about his  communication M.O..
he is explicitly careful, 
from the start of things, 
to provide a cautionary  warning 
about "categorical thinking": 
that is, the danger of being stuck 
in so-called 'buckets' (or "-isms")
of interpretation.

Why might this be useful, and how does it tie in?




Don't be alarmed by the length, 
the part we're interested in (albeit myopically) 
starts at just past the one-hour mark.

However, the whole video (series) is unequivocally worth watching: 
it's extremely helpful to note 
that this course was designed so that 
individuals don't necessarily need to come from 
a canonical science background, 
which amounts to a friendly 
(rather than blistering) 
rate of introduction to the material.

A couple quick notes:
Sapolsky's commentary on
contemporary refinements of "group selection" theories
 seems roughly parallel  to the 

Why bother to try the analogy? 
Well, it helps to illustrate a trend in biology to 
develop a theory which may be false 
as a dominant mode or mechanism
but one that may accurately predict an outcome 
of some other theory when 
a special set of circumstances are applied. 


In a very loose analogy to physics,
the dynamic is akin to the 
seemingly dichotomous relationship 
between classical "Newtonian" models 

The first model, when applied over the whole range,
fails to accurately explain certain phenomena, but 
can be fully accounted for 
by the predictions of the second theory.


The most abstracted way 
to summarize the importance 
of such a review is the following:

"assumptions about evolutionary hypotheses 
cannot be made from within an absolutist standpoint, 
(such as the notion that every trait is adaptive) 
but must be accountable to 
empirical scrutiny at all levels, 
such as genetics or population mathematics."

Another great point that was highlighted described Gould's "spandrels"
which ties in perfectly to the anthropocentric fallacies of the Cabbages post. 

Once again, it seems there is a nearly irresistible tendency 
to believe that evolution somehow strives for/achieves "perfection" 
as opposed to "just good enough".

Tremendously complicated arguments,
but absolutely critical to an understanding of evolution.

Hopefully, this post was a fair treatment that sparked your curiosity.
If it didn't, SPARK.

Let's meet here at some point in time, but only when entropy has increased.
