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 the change in frequency of the alleles in a gene pool over time; evolution is when a population of species gets more suited to its environment over time. Evolutioâ¦n occurs with mutations and natural selection. What happens is that in a population of species, not all of them are the same.
