Case notes. Planet #3, Star-System #495177230648683. Deep archaeological analyses indicate rapid evolution of intelligent primate species followed by sudden decline/disappearance. Unlike previous extinctions, appears self-inflicted. Evidence from widely-scattered artefacts suggests that the early social-cooperation instinct universal to all advanced species was – for reasons yet unclear – supplanted by an overwhelming urge to compete. This set individual against individual and group against group, leading to chronic over-consumption of resources. Undervalued and depleted natural-science investigation meant rear-guard efforts to shepherd/conserve environment too little, too late. Full contact with remaining species awaits detailed linguistic analysis but positive signs observed in early encounters with ants and cockroaches.
