      The theory of evolution, a cornerstone in biological sciences, provides a comprehensive framework to understand the diversity of life on Earth. In essence, it suggests that species change over time through a process of descent with modification. Here are key points:

      1. Descent with Modification:
        • Species share a common ancestry and have descended with changes over time.
      2. Natural Selection:
        • The mechanism driving evolution.
        • Organisms with advantageous traits for their environment are more likely to survive and reproduce.
      3. Adaptation:
        • Species evolve traits that enhance their survival and reproductive success in specific environments.
      4. Common Ancestry:
        • All living organisms are interconnected through a shared evolutionary history.
      5. Fossil Record:
        • Fossil evidence provides a chronological record of past life forms, documenting transitions between species.
      6. Genetic Evidence:
        • Modern genetics supports the theory, revealing commonalities in DNA among different species.
      7. Speciation:
        • New species can arise through the gradual accumulation of small genetic changes over time.

      The theory of evolution, proposed by Charles Darwin in the 19th century, has undergone refinement with advancements in genetics and paleontology. It remains a fundamental concept in biology, offering a powerful explanatory framework for the incredible diversity of life observed on our planet.
