Hominid Evolution, Neolithic Revolution, and Anthropological Concepts

Hominid Evolution and the Rise of Civilization

The Genus Homo: Key Species Characteristics

Homo Erectus (2 Million Years Ago)

  • Spread across Eurasia.
  • Variable brain size (546–1,251 cc).
  • Used fire, hand axes, and tools.
  • Organized hunting groups show early cooperation and social organization.
  • Brain development ended in childhood, meaning young individuals had to become independent earlier than modern humans.
  • Possibly monogamous; evidence of care for injured individuals.
  • Omnivorous diet (meat and plants); evidence of food sharing and symbolic behavior.

Homo Habilis

  • Made and used simple stone tools for cutting and breaking.
  • Did not hunt large animals; they scavenged leftover meat from carcasses killed by other predators.
  • Lived in groups of 70–80, aiding mutual protection.
  • Brains were small compared to modern humans, showing limited intelligence, though specialization began.
  • Small, hairy, omnivorous, and long-limbed for climbing and moving.
  • Tools were irregular and simple, not made following a consistent pattern, indicating limited thinking and planning skills.

Homo Neanderthalensis (430,000–40,000 Years Ago)

  • Made advanced tools and used fire.
  • Created art and music; buried their dead.
  • Groups were smaller than Homo habilis due to limited resources.
  • High mortality rate, as many children did not survive to adulthood.
  • Brain size: 1,300–1,600 cc (larger than Homo habilis), suggesting advanced thinking, problem-solving, and social skills.
  • Cared for the sick, practiced rituals, and had complex communication/language.
  • Approximately 20% of their DNA is present in modern humans outside Africa.

Homo Sapiens (Originating ~300,000 Years Ago)

  • Fully developed language and complex communication.
  • Traded goods and resources between groups.
  • Created elaborate art: paintings, carvings, and ornaments.
  • Global migration timeline demonstrates adaptability and advanced technology:
    • Eurasia: 60,000 years ago
    • Australia: 65,000 years ago
    • America: 15,000 years ago
    • New Zealand: 300–1,280 CE

The Neolithic Revolution (Appeared ~13,000 Years Ago)

This period marked the beginning of farming and animal husbandry, leading to profound societal changes.

  • Origin and Spread: Started in Southwest Asia, spreading globally because as the Ice Age ended, the climate became warmer and more stable, allowing wild plants and animals to thrive, making farming possible.
  • Settlement: Humans stopped moving to follow food sources and began living in permanent villages (e.g., Tell Abu Hureyra).
  • Consequences: Led to larger populations, complex social structures, and civilization.

Key Innovations and Impacts

  • Food Production:
    • Crops: Wheat, lentils, rice, corn.
    • Domesticated livestock (sheep, goats, cows), providing a reliable and abundant food supply.
  • Societal Changes:
    • Creation of permanent villages and towns.
    • Began trade due to food surplus.
    • People could focus on specialized jobs other than farming (crafts, tool-making, art).
  • Social Structures:
    • Emergence of social hierarchies and gender inequality.
  • Health Impact:
    • Living close to animals and higher population density led to diseases.
    • Nutrition and life expectancy sometimes decreased.

Core Concepts in Anthropology and Human Thought
