Engels' Laws of Evolution

Engels’ Laws of Evolution describe how biological traits change over generations through natural selection. First, variations within a species occur naturally. Second, some of these variations give individuals advantages in survival and reproduction. Third, these advantageous traits become more common over time, shaping the species’ characteristics. Lastly, these changes are gradual, occurring through steady accumulation of small differences. Overall, Engels emphasizes that evolution is driven by natural variation and selection, leading species to adapt to their environments over long periods.
