The Modern Theory of Evolution
The Modern Theory of Evolution combines Charles Darwin's ideas about natural selection with genetics. It explains how species change over time through gradual processes. Variations occur in traits among individuals; those with traits better suited to their environment are more likely to survive and reproduce. This leads to the passing on of advantageous traits to future generations. Over long periods, these small changes can result in the emergence of new species. Essential to this theory is the understanding of genetic inheritance, which helps explain the diversity of life and how organisms adapt to their surroundings.
