English: This diagram displays the four key stages of natural selection that form a cycle, that over time will cause a population to evolve. Here the beetles are all in the same population with a variation of their physical characteristics. Here the brown color is a more adapted characteristic as it allows the beetle to blend in with its environment and more likely to survive predation. As the brown color beetle is more likely to survive it is more likely to pass on its genetics to its offspring and overtime as more and more brown beetles survive and the other color beetles do not the population will shift to being a majority of brown beetles.
