What does evolution refer to?

Evolution refers to the change in a kind of organism over time, which encompasses genetic changes that occur across generations within a species. This process is driven by mechanisms such as natural selection, mutation, genetic drift, and gene flow. Over long periods, these changes can lead to the development of new species from common ancestors, showcasing the adaptability and diversity of life.

Understanding evolution is crucial in fields like biology and nursing, as it helps explain the development of antibiotic resistance in bacteria or the spread of diseases, and informs strategies for patient care and public health. The concept of evolution encapsulates not just shifts in physical characteristics, but also adaptations that enhance survival and reproduction in specific environments. This comprehensive view of change underscores the importance of evolution in understanding life sciences.
