Evolutionary science is the study of how living organisms change over time through processes like natural selection, mutation, and genetic drift. It explains how species adapt to their environments and how new species arise from common ancestors. This field combines insights from various disciplines, including genetics, paleontology, and ecology. One of the key figures in evolutionary science is Charles Darwin, who proposed the theory of evolution by natural selection in the 19th century. His work laid the foundation for understanding the diversity of life on Earth. Today, evolutionary science continues to explore the mechanisms of evolution and the relationships between different species.
