    Study Notes

    Charles Darwin and the 19th Century Transformation in Thought

    • The 19th century saw a profound shift in understanding of nature and life's diversity.
    • Charles Darwin's work, particularly On the Origin of Species, revolutionized biology.
    • Darwin's ideas about evolution by natural selection are still central to modern biology.
    • Darwin's theories remain highly influential and often spark debate.
    • Darwin was born in 1809.
    • Darwin's book On the Origin of Species was published in 1859.

    Darwin's Life and Work

    • Darwin, born in Shrewsbury, England, was a naturalist.
    • He embarked on the voyage of HMS Beagle from 1831-1836, collecting specimens and data across the globe.
    • His observations formed the basis for his ideas on evolution.
    • Darwin developed theories about how organisms adapt, leading to the development of new species.
    • This understanding had roots in his grandfather's work and 19th-century geological & biological theories.
    • The Origin of Species detailed his views on natural selection.
    • Darwin continued publishing, writing on diverse topics including orchids, worms and emotions.

    Darwin's Origin of Species

    • Key concept: Evolution by natural selection.
    • Explains the diversity of life's variety as the result of gradual change through time.
    • Three Essential Elements:
      • Reproduction: Offspring resemble parents.
      • Variations: Differences exist between generations.
      • Selection: Beneficial traits favour survival.

    Darwin's Global Network

    • Extensive letter writing: Developed scientific relationships globally.
    • Collaborations: Sought observations and specimens from others around the world.
    • His scientific theories, and his extensive correspondence with scientists, was essential to creating his theories.
    • Darwin's correspondence reveals the importance of collaboration and knowledge-sharing.

    Evidence for Evolution

    • Fossil comparisons: Showed gradual change over time.
    • Comparative anatomy: Analyzed similarities in body plans & bones across species.
    • Embryological comparisons: Highlighted commonalities in early development.
    • Distribution of species: Examined how different species inhabit specific environments, relating to isolation.
    • Galapagos finches: Showed how environmental pressures drove changes in beak size & shape, supporting natural selection.

    Evolution and Religion

    • Darwin's work sparked intense debate about its implications for religious belief.
    • Some saw Darwin's ideas as opposed to a divinely created world.
    • Others believed it was possible to reconcile scientific and religious worldviews.

    How new species evolve

    • Separation: Populations geographically isolated may evolve into different species.
    • Variation: Small changes in behaviour or other traits, can eventually lead to distinct species – if isolated.

    Evolving Humans

    • Humans are a part of nature, evolving from earlier life forms.
    • Changes in human genetics led to key features like larger brains, upright walking and language.
    • Evolution is an ongoing process that can be traced through study of fossil evidence, DNA, and tools.

    How Genomes Evolve

    • Genomic change is fundamental to evolution.
    • Genetic variations can be neutral, detrimental or advantageous.
    • Duplication of genes can lead to entirely new functions.
    • 'Junk' DNA may play roles in adaptation.
    • Studying full genomes sheds light on evolutionary processes.

    Evolution today

    • Evolution is still evident in the natural world, with examples like antibiotic-resistant bacteria.
    • Current research continues to detail how evolution works and what challenges it encounters.
