physiogeny
The study of the evolution of functions and vital activities by observing the supposed ontogenic recapitulation of that phylogeny.
historical, rare, uncountable
Es wird daher erst die Aufgabe einer zukünftigen Physiogenie sein, die Entwickelungsgeschichte der Functionen mit gleichem Eifer und Erfolge in Angriff zu nehmen, wie dies für die Entwickelungsgeschichte der Formen von der Morphogenie längst geschehen ist.
Where it comes from
Simplified learned borrowing from German Physiontogenie, itself from physio- + Ontogenie; equivalent to a reduction of physio- + ontogeny to physio- (“nature”) + -geny (“origin”). The simplification means that the term is also used to translate German Physiogenie, the distinction between Physiontogenie and Physiogenie not being made in English.
