Money
As a concept, money has persisted for approximately 5,000 years, evolving from Mesopotamian clay tokens through precious metals, paper notes, and digital abstractions. Each transformation has strengthened rather than weakened its grip on human affairs. The concept appears evolutionarily selected for survival, adapting to every technological and social revolution without diminishment. Money's longevity seems assured.
Panda
The giant panda has existed in recognisably modern form for approximately 2 to 3 million years, though their ancestors diverged from other bears some 19 million years ago. Having survived ice ages and continental shifts, the species recently faced extinction before human intervention. Current wild populations number approximately 1,800 individuals, their longevity now dependent entirely upon human protection efforts.
