asexuality

The same holds for Vincentius Victor in his discussion of the asexuality of the corporeal form of the soul. In Lactantius, who emphasizes the uncertainty concerning the sex of the phoenix, and in Zeno of Verona, who says that the phoenix is for itself both sexes, the background is again formed by the inferred asexuality of the phoenix.

The asexuality of insects is, in almost all cases, known to be a derived condition. That is, their evolution was contingent on the sexuality of their ancestral forms.
