Physics of Human Evolution

We start with the single-looped circuit, identifying how a shunt can exist and the path it takes

The establishment of a pulmonary passage is key in the transition to a double-looped human circuit. This lecture establishes the mechanism of translation of the pharyngeal capillary bed from gill filaments to alveoli as the double-looped circuit develops. 

In this lecture, the conceptual single-looped, axially rotated circuit is translated to the structural anatomy of the fish circulation. 

Relating the loop-in-loop to extant anatomic arrangements, we see how an anatomic shunt arises and how the transitionary polar-switching circuit maintains a homeostatic balance in the geomagnetic field.

The loop-in-loop spatial relationship of the transformative circuit is best understood by first developing a physical model to capture its pivoting and precessing actions

In this lecture we define a polar co-ordinate algorithm that describes the spatial relationship of the interdependent central loops in translation

We start with the loop-in-loop dynamics in the pharyngeal arches and expose the mystery of the disappearing 5th arch...

In polar translation, as the central loops pivot toward perpendicular parity, the aortic arch and great vessels are derived.

This lecture highlights how the pulmonary passage develops in polar co-ordination with the involuting pharyngeal filaments.

The separate atrio-ventricular trajectories of the double-looped human heart are derived geometrically from the single-looped fish heart and the balance of flows between the serialiised loops is considered

In this lecture, we equate spiralled dynamic flows into the dorsal aorta with maintaining a bi-segmental  somatomeric perfusion pattern and use the clinical condition of dextrocardia as a case-in-point

In the geometrical transformation we see how the dorsaly-located cardinal veins are levered apart and re-purposed as the spiralled aortic line develops

In this lecture we will see how the atrio-ventricular angle is retained in translation from a single to a double-looped-circuit and also ponder why the angle of ejection is this sharp reflection on itself. 

Here we put the entire sequence together, tracing the transition from fish to human, through our blood, and see how the allantoic vein is an accelerated source of the oxygenated loop-in-loop shunt in gastrulation 

The loop-in-loop is an oxygen-driven system and here we review animal evolution against environmental oxygen levels the past 500 million years

As an observation, the polar-switching haem electron-carrier circuit mirrors vertebrate evolutionary progression and cardio-morpho-genesis.
