The process of natural selection is as follows: Individuals within a biological population possess different characteristics. Those individuals with the most adaptable traits are most likely to survive and reproduce. Their offspring inherit the genetic traits of their predecessors, allowing them to continue successfully reproducing. Over generations of evolution, individuals with good genetic traits are favored for reproduction, while those unable to adapt to environmental changes find it difficult to survive and reproduce. Over time, species that do not adapt to their environment gradually disappear from the population.
