This is somewhat analogous to Region 1 and Region 2 currents in the terrestrial auroral zone (Iijima and Potemra, 1976) where currents flow into the ionosphere, across the auroral zone, and then back out of the ionosphere.
In the terrestrial auroral zone, such secondary effects produce the auroral electrojets (Boström, 1964; Carlson and Egeland, 1995).
Electron acceleration events, especially localized events, are similar in many ways to events observed in the terrestrial auroral zone.
This theory is in line with the idea of an 'escape from the terrestrial adaptive zone'.
The concept of a terrestrial 'adaptive zone', or constrained area of morphospace associated with function, was originally suggested by [ 32] for the pinniped ankle.
In order to examine the idea of a terrestrial adaptive zone in the cranium, we must first establish convergence of fissipeds within a confined region of morphospace and second demonstrate that morphological variation in the cranium is functionally related to their environment [ 32].
Core management units should instead reflect heterogeneous groups of wetlands together with terrestrial buffer zones and travel corridors between wetlands.
In such cases we argue that the different wetlands offer complimentary resources and that managing wetlands as isolated units, even with generous terrestrial buffer zones, would not likely conserve core habitats needed to maintain local abundance or persistence of populations over the long term.
That's pretty much what happened about 2.2 bya, except the consequences were a tad more severe: the killing of millions of terrestrial and photic zone obligate anaerobes, food shortages, global freezing, etc., all because an organism was completely indifferent to the well-being of others.
