The Study of History & Origins of Civilization – Comprehensive Bullet-Point Notes

Myths About the Origin of the Earth

  • Myth = traditional story explaining natural or social phenomena, often involving supernatural beings.

  • Rationale for inclusion: shows universal human need to explain beginnings before modern science.

Sumerian Tradition (Mesopotamia)

  • Content not detailed in slides but worth noting Sumerians’ cosmic ocean, gods An, Enlil, Enki, creation from clay.

Chinese Mythological Figures

  • Lei Gong (Thunder God), Tian-Mu (Mother of Lightning), Guan Yu, Shou-Hsing (Longevity), Zhu Rong (Fire), Nezha, Yen-Lo Wang (Underworld), Yu Huang (Jade Emperor), Kui Xing (Exams), Xi Wang Mu (Queen Mother of West).

  • Illustrates polytheistic hierarchy explaining natural forces and social order.

Hindu (Indian) Deities

  • Trimurti concept: Brahma (Creator), Vishnu (Preserver), Shiva (Destroyer).

  • Additional gods: Rama, Krishna (avatars of Vishnu), Ganesha (remover of obstacles).

  • Cyclical cosmology: universe created, preserved, destroyed in endless cycles (kalpas).

Japanese Shintō Deities

  • Izanagi & Izanami: primordial creators of Japanese islands.

  • Amaterasu (Sun), Susanoo (Storms), Tsukuyomi (Moon), Kagutsuchi (Fire), Hotei, Bishamon, Inari (Rice/Fox), Kaminari (Thunder), Mikaboshi (Chaos).

Ancient Greek Pantheon

  • Twelve Olympians & others: Zeus, Hera, Poseidon, Demeter, Athena, Apollo, Artemis, Ares, Aphrodite, Hermes, Dionysus, Hades.

  • Myths offer explanations for seasons (Demeter & Persephone), lightning (Zeus), etc.

Filipino (Visayan) Creation Myth

  • Not fully detailed; generally includes deities like Kaptan (sky) and Maguayan (sea) where world forms from their grand-children’s union.

  • Link to local geography—archipelagic setting, respect for sea/sky.

Scientific Theories on the Origin of the Earth / Universe

Nebular Theory (a.k.a. Solar Nebular Disk Model)

  • First outlined by Emanuel Swedenborg (1734); refined by Immanuel Kant (1755) & Pierre-Simon Laplace (1796).

  • Modern revamp by Viktor Safronov (1970s).

  • Core idea: A rotating nebular cloud collapsed under gravity, flattening into a disk; Sun formed at center, planets from accretion of dust/gas.

  • Predicts ordered planetary orbits and prograde rotation.

Planetesimal Theory

  • Proposed by Thomas Chamberlin & Forest Ray Foulton (1905) to challenge Laplace’s purely nebular model.

  • Suggests Sun interacted with a near-passing star; tidal material condensed into “planetesimals” that clumped into planets.

  • Accounts for varying angular momentum but less favored today.

Big Bang Theory

  • Origins: Aleksandr Friedmann & Georges Lemaître (1920s); elaborated by George Gamow (1940s).

  • Universe began from extremely hot, dense singularity ≈13.8 billion years ago\approx13.8\ \text{billion years ago}, expanding and cooling.

  • Evidence: cosmic microwave background (CMB), red-shift of galaxies (Hubble’s Law), primordial abundances of 4He, 2D, 3He, 7Li^4\text{He},\ ^2\text{D},\ ^3\text{He},\ ^7\text{Li}.

Creationism and Evolutionism

Core Tenets of Creationism

  • A single divine Creator responsible for life and cosmos.

  • Names vary by religion: Yahweh (Judaism/Christianity), Allah (Islam), Brahma (Hinduism).

Darwinian Evolution

  • Charles Darwin, “On the Origin of Species” (1859).

  • Mechanism: Natural Selection — differential survival & reproduction.

  • Works on “comparative advantage,” not absolute design perfection.

  • Species unable to adapt face extinction; adaptable species diversify.

Catholic Church’s Evolving Position

  • 1950: Pope Pius XII encyclical “Humani Generis” – evolution a “serious hypothesis” worthy of study; spiritual soul still divinely created.

  • 1996: St. John Paul II to Pontifical Academy — evolution “more than a hypothesis,” body may evolve from pre-existing matter, soul from God.

  • Pope Benedict XVI (Joseph Ratzinger) — “In the Beginning” commentary: affirms compatibility of faith & scientific creation narratives.

Theistic Evolution

  • God may employ evolutionary mechanisms; “Six Days” symbolic of vast epochs.

  • Bridges literal creationism and secular evolution.

Two-Phase Model of Human Evolution

  • Homonization: physical transition from ape-like to human-like morphology.

  • Sapientation: brain enlargement, higher cognition, language, culture.

Hominids (Earliest Humans)

  • Quadrupedal, body hair, small brains.

  • Example: Ramapithecus — discovered Siwalik Hills (India/Pakistan), existed ≈15 million years ago\approx15\ \text{million years ago}, height 1.1 m1.1\ \text{m}, orangutan-like jaw.

Homo Habilis — “Handy Man”

  • Existed 2.3–1.5 million years ago2.3 \text{–} 1.5\ \text{million years ago}.

  • First clear tool users (Oldowan tools).

  • Traits: larger brains, slight forehead, smaller jaws, dexterous finger bones.

Homo Erectus — “Upright Man”

  • Appeared ≈1.8 million years ago\approx1.8\ \text{million years ago} in Africa; first to migrate widely (Asia, Europe).

  • Discovered controlled fire; uses: cooking, warmth, protection.

  • Features: bigger brain & body than habilis, thicker cranial bones, downward-facing nostrils (modern-like nose).

Regional Specimens

  • Java Man (Pithecanthropus javanensis) — found 1891 by Eugene Dubois, Trinil, Java.

  • Peking Man (Sinanthropus pekinensis) — Zhoukoudian caves, China; lifestyle: hand-axes, fire; remains dated ≈420,000 years\approx420{,}000\ \text{years} old.

  • Homo floresiensis (“Hobbit”) — Flores Island, Indonesia; stature <1\ \text{m}, weight ≈25 kg\approx25\ \text{kg}, brain 13\frac{1}{3} modern size; lived 95,000–13,000 years ago95{,}000–13{,}000\ \text{years ago}.

  • Homo luzonensis — Callao Cave, Cagayan (Philippines); remains dated 67,000–50,000 years ago67{,}000–50{,}000\ \text{years ago}; teeth, hand/foot bones, femur fragments indicate mosaic of primitive & modern traits.

Homo Sapiens — “Thinking Man”

  • Emerged ≈300,000 years ago\approx300{,}000\ \text{years ago} (Morocco fossils).

  • Anatomically modern humans: high forehead, chin, reduced brow ridges.

  • Behavioral modernity (symbolic art, complex tools) by ≈50,000 years ago\approx50{,}000\ \text{years ago}.

  • Only surviving hominin species after Neanderthal & Denisovan extinction.

Geographic Context of Early Humans

  • Early hominids originated in East Africa’s Rift Valley (fossil concentration, varied ecology).

  • Glacial/inter-glacial cycles influenced migrations out of Africa.

  • Land bridges (e.g., Sunda & Sahul shelves) enabled movement into Southeast Asia & Australia.

Way of Life of Early Humans

  • Foraging, hunting, simple stone tool industries (Oldowan, Acheulean, Mousterian).

  • Control of fire enhanced diet (cooking = higher caloric extraction), social bonds, protection.

  • Gradual shift to cooperative hunting, language development, later agriculture (Neolithic Revolution ≈10,000 BCE\approx10{,}000\ \text{BCE}).

Ethical / Philosophical Implications

  • Understanding origins fosters respect for cultural narratives and scientific evidence.

  • Debate over creation vs. evolution informs dialogue between science, religion, and education.

  • Recognition of shared ancestry promotes anti-racism and global citizenship.

Connections to Previous / Future Topics

  • Builds on earlier lessons about evidence types (fossils, stratigraphy, radiometric dating).

  • Prepares groundwork for studying Neolithic Revolution, ancient civilizations (Mesopotamia, Egypt) in subsequent units.

Practical Takeaways for Daily Life

  • Critical evaluation of sources (myth vs. science) trains information literacy.

  • Awareness of evolution informs medical science (e.g., antibiotic resistance as natural selection).

  • Appreciation of cultural myths enhances multicultural competence.
