Genetic evolution

Genetic evolution is the process by which the inherited traits of a population change over time as organisms with advantageous characteristics survive and reproduce more successfully than others. Through this mechanism, called natural selection, beneficial traits become more common in a population across generations while less useful ones may disappear, gradually shaping species to better fit their environments. This fundamental process explains the remarkable diversity of life on Earth and how all living things are connected through common ancestors stretching back billions of years.
