0036 Here are the adaptations proposed by Daniel Turbon in sections one and two of his paper, “The Distinctive Character of Human Being in Evolution”.

I continue.

0037 In Section 2.2, Turbon mentions brain reorganization and size increase, over very long periods of time.  The parietal and frontal lobes preferentially enlarge.  Encephalization increases.

There is more here than meets the eye.  The brain not only increases but reorganizes.  This is covered in Comments on Steven Mithen’s Book (1996) Prehistory of Mind.  The way hominins think changes over many, many generations.  So does the brain’s architecture.

In Section 2.3, Turbon attaches importance to the FoxP2 regulatory gene.  Mutations in the gene produce impediments to speech and writing.  Scientists link the FoxP2 gene to neuro-motor control of rapid recursive and coordinated actions.  Neanderthals and humans share identical FoxP2 gene sequences.  Turbon associates this gene to speech-alone talk.  The gene equally applies to hand talk.

0038 The dyad of the brain [adapts to] talk is covered in Comments on Derek Bickerton’s Book (2014) More Than Nature Needs.   Our brain to body ratio is large.  It’s so large as to seem to be more than necessary for survival.  But, for talking, that is a different matter.

Also, children pick up language with a paucity of clues.  More cognitive processing is needed for that.  The question is, “How to model linguistic communication, in order to account for how children bootstrap language use.”  The answer is wrestled with in Comments on Robert Berwick and Noam Chomsky’s Book (2016) Why Only Us?

0039 In section 3.1 and 3.2, Turbon discusses a potential concurrent adaptation in the domestication of fire (starting around 800,000 years ago) and advances in stone tool technologies (starting around 500,000 years ago).  There seems to be a transition, here.  Why do these two extra-somatic adaptations occur in tandem?

These questions are addressed in Comments on Clive Gamble, John Gowlett and Robin Dunbar’s Book (2014) Thinking Big.  Increasing neocortex size correlates to larger group sizes.  Larger group sizes correlate to larger brain size.  Do I detect a feedback loop?  Does this feedback loop ramp up with the adaptations of cooking and hunting with composite wood and stone tools?

0040 In Sections 4 and 5, Turbon discusses the evolution of the family.  Increasing encephalization means bigger heads.  In order to fit through the birth canal, big-brained babies are born early.  They are helpless infants.  Infant helplessness should lead to higher mortality in the dangerous environment of the open savannah.  The family is one adaptation that decreases risk for infants and children.  So are other social circles, such as the team, the band, and finally, the community.

0041 Finally, in Section 6, Turbon discusses altruism.

0042 In the previous blog, I considered the adaptations listed by Turbon, in addition to high-level cognition, extra-somatic culture and talk (language).

Here is the list.

0043 All these are adaptations.  Adaptations exploit a niche.  So, in the ongoing two level interscope, the distinctive character_1b sustaining a noumenal origin of human_2b in the normal context of human intuition_3b, must be the human niche_1b.  The human niche_1b, in turn, virtually situates Turbon’s list of adaptations_1a.

Here is the reconfigured interscope.

0044 What is the human niche_1b?

This is the central claim in the masterwork, The Human Niche.

The human niche_1b is the potential of triadic relations_1b.

0045 Every adaptation_1a detailed by Daniel Turbon exploits triadic relations_1b.

Once the origin of human beings_2b is appreciated in terms of signs, category-based nested forms, judgment and other triadic relations_1b, then our adaptations_1a appear like observable and measurable facets_2a of a single noumenon, the human niche_1b.

0046  Turbon’s appeal in the last sentence of his abstract receives has already been answered.

A Course on the Human Niche is available on the smashwords website.  Search the following terms on the internet: human niche course series Razie Mah smashwords.  Any reasonable browser will point the reader to the location containing A Course on the Human Niche.

0047 The course begins with a Primer on Natural Signs.  The medieval scholastic tradition ends, in the 1600s, and the philosophy of Charles Peirce begins, in the 1800s, with an inquiry into the nature of sign relations.  Signs, like all triadic relations, entangle the material world.  However, material and instrumental causalities cannot account for triadic relations.

0048 Then, the course offers commentaries on four books by modern thinkers on human evolution.  These commentaries are:

Comments on Clive Gamble, John Gowlett and Robin Dunbar’s Book (2014) Thinking Big

Steven Mithen’s Book (1996) Prehistory of Mind

Comments on Derek Bickerton’s Book (2014) More Than Nature Needs

Comments on Robert Berwick and Noam Chomsky’s Book (2016) Why Only Us?

0049 The course wraps up with the masterwork, The Human Niche.

0050 In sum, A Course on the Human Niche, offers an approach to the alignment of philosophy and science dwelling in the heart of Turbon’s essay.
