    Study Notes

    Biological and Cultural Evolution

    • Biological evolution involves physical changes in humans, including bone structure, brain size, and dentition over generations.
    • Key aspect of biological evolution is the study of bipedalism, which refers to walking upright on two feet.
    • Cultural evolution denotes the progression of human societies from simple to complex cultures due to adaptations to challenges such as climate and population growth.
    • Artifacts and tools are reflective of cultural evolution and are studied to understand changes in human lifestyles.

    Charles Darwin and Darwinism

    • Charles Darwin introduced the theory of evolution, which states that species develop through natural selection and inherited variations.
    • Three principles of natural selection:
      • Variation among individuals.
      • Heritability of traits.
      • Reproductive success of better-adapted organisms.
    • Darwin posited that species better suited to their environments survive and propagate their traits through generations.

    Key Concepts

    • Evolution: Change in species characteristics over generations, driven by natural selection.
    • Dentition: Arrangement and condition of teeth in a species.
    • Progeny: Offspring or descendants of a biological entity.
    • Bipedal: Walking using two legs.
    • Genus: Biological classification ranking between family and species, always capitalized in naming.

    Evolution of Early Humans

    • Biological evolution includes genetic modifications in populations across generations.
    • Homo erectus:
      • Lived from 1.8 million to 300,000 years ago.
      • Average brain size approx. 1000 cc; height about five feet.
      • Known for advanced tool-making including hand axes and usage of fire.
      • First to develop spoken language, facilitating cooperation and social interaction.
      • Engagement in religious rituals, with evidence of burial practices.
      • Significant fossils found in Java (Java man) and China (Peking man).

    Homo Sapiens

    • Homo sapiens neanderthelensis:

      • Larger brain size than modern humans; strong and muscular.
      • Carnivorous diet with tools reflecting hunting lifestyle.
      • Resided in more comfortable caves, exhibiting social living.

    • Homo sapiens sapiens:

      • Modern humans characterized by reduced size and brain size (about 1300 cc).
      • Evolved features include smaller jaws, rounded skulls, and development of art and complex tools.
      • Cro-Magnon considered early Homo sapiens dispersed across Europe, Australia, and the Americas with diverse diets and advanced thinking capabilities.
