Abstract The longitudinal study was conducted to observe what has been regarded as the Final Filter of Civilization among 3-dimensional lifeforms. While preceding observations provided valuable insights for the mechanism, this study considered variables hypothesized to be more relevant. After searching extensively, a suitable candidate was found on a solid-state planet orbiting a yellow dwarf star; and for the sake of standardization the observed time was measured in “years”, referring to the observed planet’s orbit. The subject race – henceforth referred as “sapients” – had evolved the inherent attribute of social affinity alongside the previously considered ones of sexual desire, aggression, self-preservation, and intelligence, associated with survival for their carbon compositions. The sapients were discovered as four-limbed, semi-bipedal climbers with…
