Tiger
The tiger has adapted to environments ranging from Siberian tundra to tropical mangroves. The Sundarbans tiger swims between islands; the Amur tiger survives temperatures of minus forty degrees. This represents remarkable evolutionary flexibility developed over millennia.
Yet the tiger cannot adapt to the modern world's most challenging environment: human civilisation. Urban tigers do not exist. Suburban tigers represent catastrophic failures of containment rather than successful adaptation. The species remains fundamentally incompatible with the dominant ecosystem on Earth.
Money
Money demonstrates supernatural adaptability. Beginning as cattle and shells, it has transformed into coins, paper, electronic signals, and now cryptocurrency. The Rotterdam School of Monetary Evolution documents over 3,000 distinct forms money has taken across human history.
Money adapts not merely to physical environments but to conceptual ones. It functions equally well in socialist and capitalist systems, in wartime and peace, in agricultural and information economies. Money survived the fall of Rome, the Black Death, two world wars, and the 2008 financial crisis. It will likely outlast the tiger by considerable margin.
VERDICT
The tiger represents biological adaptation at its finest; money represents conceptual adaptation at its most relentless. While the tiger struggles to coexist with motorways, money has colonised every human institution without exception. Adaptability victory to the abstract entity.
