QUESTION: What is evolution? As it is most famously used, evolution is the process by which an organism becomes more sophisticated over time and in response to its environment. The Theory of Evolution is currently the most popular concept of how life reached its current state.
Evolution is a scientific theory used by biologists. It explains how living things change over a long time, and how they have come to be the way they are. The Earth has been around for a very long time. By doing research on the layers of rock, we can find out about its past.
