0001 Chris Sinha, writing from Hunan University, publishes another article on human evolution.  The journal is Interaction Studies (volume 19(2), 2018, pages 239-255).  The complete title is “Praxis, Symbol and Language: Developmental, Ecological and Linguistic Issues”.

The title of Razie Mah’s commentary is Comments on Chris Sinha’s Essay (2018) “Praxis, Symbol and Language”. The commentary is found at the smashwords website under the series: Buttressing the Human Niche.  Other vendors also sell the e-commentary.

0002 This blog complements the commentary.

0003 Sinha’s article covers from the start of the Homo genus, around two million years ago, to the speciation of Homo sapiens, around two-hundred thousand years ago. That is a lot of territory.

Several issues intertwine.  One is individual development (devo).  Another is a transition in natural selection (evo) from ecology-driven adaptations (eco) to adaptations driven by social interactions (socio).

0004 Sinha loves terminology.  He searches for a EcoEvoDevoSocio framework.
