- adj. Pertaining to reversion.

- Pertaining to, or of the nature of, reversion; reversionary: specifically, relating to the appearance in any organism, plant or animal, of some character shown by its progenitors or presumably possessed by the ancestral form from which it is descended.
Sorry, no etymologies found.
On the other hand, to judge by the reversional traits which show themselves in individuals that vary from the prevailing predatory style of temperament, the ante-predatory variant seems to have a greater stability and greater symmetry in the distribution or relative force of its temperamental elements.
The former of these two characteristic variants is nearer to the generic type in each case, being the reversional representative of its type as it stood at the earliest stage of associated life of which there is available evidence, either archaeological or psychological.
The sexual organs are, then, specialized branches; but their special character does not prevent their showing occasional reversional features, recalling their primi - tive nature.
