24 That this points only to the fact of evolution, and not necessarily to actual descent, will be seen later on.

31 If we wish to, we can even read the “biogenetic law” in Dante. See “Purgatory,” p. 26, where the embryo attains successively to the plant, animal and human stages:
“Anima fatta la virtute attiva, Qual d’una _pianta_....
This is, of course, nothing else than Aristotle’s theory of evolution, done into terzarima, and corrected by St. Thomas.
For the latest application of these views, even in relation to the “biogenetic fundamental law,” see the finely finished “Morpho-genetic Studies” of T. Garbowski (Jena, 1903): “The greater part of what is usually referred to the so-called fundamental biogenetic law depends on illusion, since all things undeveloped or imperfect must bear a greater or less resemblance one to another.”
