The Structure of Evolutionary Theory

The structure of evolutionary theory explains how species change over time through processes like natural selection and genetic variation. It posits that all living organisms share a common ancestor and evolve through adaptations that enhance survival and reproduction in their environments. Key concepts include variation within populations, competition for resources, and the passing of advantageous traits to future generations. This theory is supported by evidence from various fields, including genetics, paleontology, and comparative anatomy, providing a comprehensive understanding of biological diversity and the interconnectedness of life on Earth.
