Tom, Acteon, Bat, and Austin had even finished by deserting the class, and the professor found himself reduced to Hercules alone, who seemed to him to have some natural disposition to distinguish a parasite from a thysanuran.

In general, the suggested homolgies usually start from the structures found in the Thysanuran genitalia and depend also on evidence from postembryonic developments, the structure of gynandromorphs, and the anatomical relations, musculature and innervation of the various parts.

Furthermore, that wingless Thysanuran silverfish may not look much more "advanced" than the hypothetical most recent insect ancestor that it shared with the mayflies, but fossils do not tell how much internal physiological adaptation might have occurred in the last four hundred million years or so, during which Thysanura showed little external change.

Forty years later the entomologist Lubbock paid tribute to Templeton's early work by naming a thysanuran genus after him - Templetonia.
