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 means the changes that occur in a population over time. In this definition, a âpopulationâ means a group of the same species that share a specific location and habitat. Evolutionary changes always occur on the genetic level.In other words, evolution is a process that results in changes that are passed on or inherited from generation to generation.omo erectus was a very successful species of the middle period; fossils have been found throughout Africa, Europe, and much of Asia, and the species may have survived for more than 1.5 million years. The final transition, from the middle to late periods, happened about 200,000 years ago.
