I noticed none of you can explain it in your own words. (lol)
Evolution is the process through which living organisms change and adapt over time. It is driven by two key mechanisms: genetic variation and natural selection. Genetic variation refers to the differences that exist in the DNA of individuals within a population. These variations can arise through random mutations, genetic recombination during reproduction, or other genetic processes.
Natural selection acts on this genetic variation by favoring certain traits that increase an organism's chances of survival and reproduction in a particular environment. Organisms with advantageous traits are more likely to survive and pass on their genes to the next generation, while those with less favorable traits are less likely to reproduce.
Over many generations, this selective pressure leads to the gradual accumulation of beneficial traits in a population, resulting in adaptations that enhance survival and reproductive success. This process can lead to the development of new species over time, as populations become genetically distinct and unable to interbreed.
Evolution is not a deliberate or goal-oriented process, but rather the result of the interaction between genetic variation and the environment. It is a fundamental concept in biology that explains the incredible diversity and complexity of life on Earth.
