Species variability refers to the natural differences and variations that exist within a species. These variations can include physical characteristics, behaviors, genetic makeup, and other traits. Studying species variability is important in understanding the diversity of life on Earth and how different individuals within a species contribute to ecosystem function and resilience. Researchers may investigate factors that contribute to species variability, such as genetic diversity, environmental influences, and evolutionary processes. This research area can provide valuable insights into conservation, adaptation, and evolution within a species.
