  • This episode had a major tie-in with the original series episode "Space Seed" in that Dr. Keniclius was one of the genetic supermen created in the Eugenics war of 1996.
  • In this episode, Kirk referred to the concept of IDIC (Infinite Diversity in Infinite Combinations), a tie-in to the original series episode "Is There In Truth No Beauty?"
  • In this episode, flying plant creatures menace the Enterprise landing party.
