Evolution refers to the gradual process of change and development in a particular direction over time. In biology, it specifically describes how living organisms have changed and adapted through generations, leading to the diversity of life on Earth. It is a concept that encompasses both the biological and metaphorical aspects of change, including the development of ideas, technologies, and societies.
The word "evolution" comes from the Latin word "evolutio," which means "unrolling" or "opening." It is composed of the prefix "e-" (out) and "volvere" (to roll). The term evolved to describe the idea of growth and development in a more general sense.
