How has the mean value of the number of the cactus spines in the population changed?
The mean value of the number of cactus spines in the population may have changed due to various environmental factors, genetic variations, or selective pressures. For instance, if the population has adapted to a harsher climate, the mean spine count might increase as a defense mechanism against herbivores and to reduce water loss. Conversely, if conditions favor less spiny individuals, the mean may decrease. Monitoring these changes can provide insights into the population's adaptation and resilience.

The cactus basically states "How much pain are you willing to indure to get a drink in this desert?"; Surprisingly, some animals do partake. In some cactus varieties the spines participate in water collection. Water from dew condenses on spines and, in some cactus species, downward-pointing spines help to direct rainwater to the roots of the plant. Spines help to reflect light away from the cactus stem theoretically lowering the stem temperature. Some spines also trap in a layer of air next to the cactus stem preventing loss of water via evaporative cooling.
