I've been wondering why philosophy began with rational rather than objective roots. I'm pretty sure humans knew how to observe, test, and measure when Greek civilizations rose. Evidence is abundant from Egyptian engineering that measurement accompanied observation very early on at the dawn of written language. So why did Greeks concentrate on logic and rational argument rather than hypothesis and experiment?
My take is reflected in political movements now. Itis objectively true that humans are a singles pecies and that there are no races extant in this early period of our existence. It is really easy to objectively debunk claims of race based on primarily one attribute, skin color, cultural norms are transitory rather than permanent as any reading of recent history will reveal. For instance, German culture went from authoritarian separatist, nazism, to democratic social inclusiveness, open borders, in less than fifty years.
Now I've not researched the topic yet. I'm just going on worldwide political trends to tribe in this era of social inclusiveness and one worldism such as we see in EU, America, Middle East, and far East and the continuing turmoil in Africa and S.America as nations try to climb out of corrupt authoritarian habits.
Yes there needs to be a lot of precision for this to be a social science discussion But, here, it seems to me, the best place to get such a discussion going since it is my belief there is an extential risk to objective processes bubbling up in human cultures right now.
I'm going to construct a rational frame and a scientific frame over the next few posts. The work of Stephen W. Porges serves both straw man and intellectual anchor to evolution of brain function in which I have been trained,.

Abstract:
First the boat that is floated is anchored in reptile to mammal nervous transitions. One might expect a more appropriate junction would be where hand and vocal evolution coincided with the evolution of monotremes since it is here where manipulation and interpretation become featured in behavior. So although there are general changes between reptile and mammalian behavior linkage between visceral and sensory function in the brain there needs be the additional linkage between manipulation and communication as well.

Abstract:
The polyvagal theory describes an autonomic nervous system that is influenced by the central nervous system, sensitive to afferent influences, characterized by an adaptive reactivity dependent on the phylogeny of the neural circuits, and interactive with source nuclei in the brainstem regulating the striated muscles of the face and head. The theory is dependent on accumulated knowledge describing the phylogenetic transitions in the vertebrate autonomic nervous system. Its specific focus is on the phylogenetic shift between reptiles and mammals that resulted in specific changes to the vagal pathways regulating the heart. As the source nuclei of the primary vagal efferent pathways regulating the heart shifted from the dorsal motor nucleus of the vagus in reptiles to the nucleus ambiguus in mammals, a face–heart connection evolved with emergent properties of a social engagement system that would enable social interactions to regulate visceral state.
First the boat that is floated is anchored in reptile to mammal nervous transitions. One might expect a more appropriate junction would be where hand and vocal evolution coincided with the evolution of monotremes since it is here where manipulation and interpretation become featured in behavior. So although there are general changes between reptile and mammalian behavior linkage between visceral and sensory function in the brain there needs be the additional linkage between manipulation and communication as well.

There are multiple time-scales that are relevant for understanding how a given phenotype emerges. Brains change across large, evolutionary time-scales, shorter time-scales such as generations, and within the life of an individual.Any given phenotype is a combination of genes involved in brain and body development, behavior, and the environment in which an individual develops. A similar phenotype in different species may be due to homology, but can also be the result of a different combination of factors.
There are several constraints that restrict the avenues along which evolution of the brain and body can proceed. One of these constraints is the contingent nature in which genes are deployed during development. Another constraint is genetic pleiotropy; a single gene can be expressed in different portions of the nervous system at different times in development and can be involved in different aspects of brain and body organization. Finally, the laws of physics constrain brain evolution.
The human neocortex has an extraordinary capacity to adapt based on context, allowing for rapid phenotypic change even within a single generation. Our species has also evolved a remarkably fluid brain/body interface with the environment, such that tools and machines can be incorporated into our body schema, which extends our embodiment and peripersonal space.
