The Prehistoric Era

Biblical Calculation of Creation:
- Around 350 years ago, English clerics calculated the moment of creation to be on Sunday, October at 9 AM.
Progress and Learning:
- Significant progress has been made in understanding our origins since that calculation.
- Future generations will likely view our current understanding with the same scrutiny.
Consensus View of Scientists and Historians:
- The following timeline represents the current consensus, subject to change with new discoveries (e.g., James Webb Telescope).
Timeline of Events:
- Big Bang: Approximately $13,800,000,000$ years ago (some suggest $27,000,000,000$ years ago).
- Formation of Sun, Earth, and Solar System: Approximately $4,500,000,000$ years ago.
- Extinction of Dinosaurs: Approximately $66,000,000$ years ago.
- Appearance of Hominids: Approximately $7,000,000$ years ago.
- Appearance of Homo Sapiens: Approximately $200,000$ years ago in Africa.
- Migration Out of Africa: Approximately $100,000$ years ago.
- Development of Human Language: Significant for communication, problem-solving, and knowledge sharing.
- Migration to the Americas: Approximately $16,000$ years ago.
- Development of Writing Systems: Approximately $5,000$ years ago.

Key Question: How did early humans evolve, adapt, and survive?
Goal: Challenge the perception of early humans as unsophisticated.
Resilience and Innovation: Early humans overcame obstacles through resilience, survival skills, and innovation.

Timeframe: From $200,000$ to $12,000$ years ago (a period of $188,000$ years).
Limitations: This is the largest chunk of time covered, yet the era about which we know the least.
Primary Source Record: There are real limitations with the primary source record.
Consensus View: Information presented represents the consensus view of historians and scientists.
Evolutionary Process: Humans emerged from a complex evolutionary process starting around $7,000,000$ years ago in Africa.
Hominid Subspecies:
- Various subspecies emerged, including Homo erectus, Homo habilis, and Homo sapiens.
- Homo sapiens proved to be the most adaptable and resilient.
Hunter-Gatherer Lifestyle:
- For most of their history, Homo sapiens were hunter-gatherers, lacking knowledge of farming and animal domestication.
- This lifestyle required constant movement to find food, leading to migration.
Limited Advancements: Constant searching for food limited advancements due to the focus on basic survival.
Early Tools and Technology:
- Primarily used for hunting.
- Included sophisticated stone tools, axes, bows, weapons, spears, fishing hooks, and trapping systems.
Nomadic Existence:
- Groups lived in nomadic fashion, without permanent settlements.
- Vulnerable state due to the risk of starvation.
- Inefficient system with occasional surpluses followed by scarcity.

Mastery of Fire:
- Provided warmth.
- Improved nutrition through cooking, maximizing nutrient intake and preserving food.
- Facilitated brain growth due to a more nutrient-rich diet.
- Supported long-term evolution and development.
Social Structure:
- Small migratory groups, typically tribes of 20-25 people, always at risk of overpopulation.
Development of Language:
- Verbal communication allowed for problem-solving and knowledge sharing.
- Contributed to accumulated knowledge across generations.
- Each generation could build on the knowledge of the previous one.
Artwork and Stability:
- Cave art provides insights into the animals hunted and hunting techniques.
- Indicates a level of stability, suggesting that cultures had time for artistic endeavors.

Neolithic Revolution:
- Refers to the ability to practice advanced farming.
- Occurred roughly simultaneously across the world.
- Independent discovery in each region due to intense environmental change.
Environmental Changes:
- End of an ice age with increasing global temperatures.
- Extinction-level events for many mammals, impacting hunter-gatherer diets.
- Increased temperatures made previously inhospitable areas suitable for agriculture.
Domestication of Animals:
- Began around 9000 BCE (approximately 11,000 years ago) to 2000 BCE.
- Rooted in understanding that animals could be manipulated and conserved if treated well.
- Various animals domesticated, including dogs, sheep, goats, and chickens.
- Provided a steady supply of meat, wool, milk, and eggs.
Human-Dog Connection:
- Evidence suggests a special connection existed as far back as 14,000 years ago.
- People were buried alongside their dogs.
Crop Development:
- Crops developed in different regions are still associated with those areas today.
- Mesopotamia: wheat and barley.
- Asia: rice.
- The Americas: maize (corn).

Stability:
- Provided humans with stability, which is the root of advanced civilization.
- Allowed humans to control nature.
- Reliable food source supported population growth.
Specialization:
- Enabled some people to specialize in areas other than food production.
- Led to the development of better crafts, tools, and buildings.
- Increased productivity in agricultural work.
Sedentary Life:
- Encouraged settled life, leading to the building of permanent homes.
- Emergence of larger settlement areas, villages, towns, and cities.
Modern Innovations:
- Many modern innovations have origins in this era.
- Trade and commerce: building blocks of economic exchange.
- Protective measures: led to the formation of states and governments.
- Early systems of accounting and taxation were developed to manage crop value.
Gender Roles:
- During the Paleolithic era, there was closer equality between the sexes.
- The Neolithic Revolution led to a gender divide.
- Women were primarily limited to domestic vocations and child-rearing.
- Men were allowed to participate in more public forums and exercised more power.
