However, the data in Figure 4 show that, like real flies, at most time points, the models have mixed character, with flies alternating between different activities (which change progressively).
Several petrologists (Whattam and Stern 2011; Stern et al. 2012) claim that their eruption follows the "subduction initiation rule" in which the magma source changes progressively in composition due to the combined effects of melt depletion and subduction-related metasomatism.
Firstly, there are "micro expressions" which change.
The SBR phase, which is continuous in the unvulcanized blend, changes progressively into the dispersed phase as sulfur concentration increases.
Phase constitution of solid solution changes progressively under different electrolyte concentration.
This kind of representation should give a more accurate sense of how the behavior changes progressively.
However an underlying mechanism is likely to be age-dependent "maturation" of relevant elements of the host response to allergens, which probably includes changes in relative IgE and IgG titres and in antibody affinity, both of which are known to change progressively with continuing exposure.
Instead one must posit a long process of gradual evolutionary change in which progressively evolved offspring inhabited progressively less brackish water, with each new species' physiology incrementally changing so that it was well evolved for its ionic environment, until the transition to being able to live in completely fresh water was achieved.
Sympathetically, this position can been seen as an urging of gradual changes, which progressively over time ameliorate the problem of inadequate care for asylum seekers.
Adipose tissue accumulation, especially visceral and ectopic (e.g., intramuscular, hepatic), induces a spectrum of metabolic and hormonal changes, which progressively impair insulin signaling.
