Formal Causality and Biology

As has been previously discussed, the extension of Modern Physics to Biological phenomena can be problematic.  In sharp contrast, the unity of the parts of an Organism can be attributed to Formal Causality. Likewise, the influence of a Species on its members, e. g. experienced instinctively, is another example of that variety of efficacy.  But, Formal Causality is a basic feature of the original concept of Physics, i. e. Aristotle's.  So, if there is difficulty in extending a Newtonian explanation to Biological phenomena, it is not a reflection of the limitations of 'Physics' per se, but merely of the Efficient Causality reductionism that constitutes one version of the enterprise.
