What is the approximate diameter of vicuña fiber, which makes it highly prized and economically valuable?
Answer
12 microns
Vicuña fiber is renowned for its extraordinary fineness, which can be as low as 12 microns in diameter. This extreme thinness results in superior thermal insulation, which helps the animal maintain a stable body temperature in the massive daily temperature fluctuations of the altiplano. This same fiber quality historically led to intense human persecution and continues to make the animal's coat highly valuable in modern economic contexts, driving unique human-mediated selection pressures.
