What does an increased variance in traits within a species typically lead to?

Increased variance in traits within a species enhances the genetic diversity and functional variability among individuals. This diversity provides a broader range of characteristics that can be beneficial in different environmental conditions. For example, some individuals may possess traits that make them more resistant to diseases, more efficient at finding food, or better suited to withstand climate changes. Consequently, a greater adaptability to changing environments emerges, as more individuals have the potential to thrive under varying conditions.

This adaptability is crucial for the survival of species in dynamic ecosystems where environmental factors can fluctuate due to climate change, habitat destruction, or other anthropogenic pressures. In summary, increased variance in traits equips a species with the necessary tools to cope with environmental challenges, ultimately enhancing its chances of survival.
