    Study Notes

    Early Ideas About Evolution

    • Evolution is the process of biological change where descendants differ from ancestors.
    • Charles Darwin wasn't the first scientist to study evolution.
    • Important naturalists in the 18th century included Carolus Linnaeus, Georges Buffon, Erasmus Darwin, and Jean-Baptiste Lamarck.

    Carolus Linnaeus

    • Proposed that species (similar organisms that can reproduce) could be grouped and have fertile offspring.

    Georges Buffon

    • Proposed that species shared a common ancestor, contradicting the prevailing thought of the time.

    Erasmus Darwin

    • His grandfather, noted more complex life forms arose from less complex forms.

    Jean-Baptiste Lamarck

    • Recognized that physical characteristics can be passed to offspring due to environmental changes.
