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.
The theory of evolution by natural selection, first formulated in Darwin's book On the Origin of Species in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.
