Human Origin and Migration

Homo sapiens originated in Africa approximately 200,000 to 300,000 years ago.
The oldest known examples of Homo sapiens date back to about 200,000 years ago.
Current knowledge is subject to change; new discoveries could alter this understanding.

Early humans began to migrate out of Africa.
- The reasons behind migration mirror modern motivations for moving.
Individuals often dislike the process of moving due to its challenges.
- Example: A student's disdain for moving, expressing a willingness to endure discomfort rather than move again.
Common motivations for migration:
- New opportunities (the most preferred reason).
- Family reasons, including both providing for and distancing from family members.
- The presence of dangerous or undesirable neighbors can motivate a move.
- Environmental factors, including weather changes (e.g., people migrating from colder to warmer climes).

Early humans, primarily hunters and gatherers, began to form civilizations around rivers.
Agriculture, identified as a significant turning point in human history, enabled:
- The ability to cultivate crops rather than constantly forage for food.
- Creation of surplus food leading to the development of languages, cultures, and myths.
- Systematic observation of natural phenomena, such as studying the sun for agricultural purposes.

Approximately 100,000 years ago, a key group known as the Proto-Indo Europeans emerged.
- They are fundamental in linguistic history: 70% of current languages can trace roots back to them.
- They were significant due to the domestication of horses, enhancing their mobility and influence.
The spread of the Proto-Indo European people facilitated cultural exchanges and migratory patterns across Europe and beyond.

Migration to North and South America is believed to have occurred around 15,000 years ago, with various theories describing how it took place.
- Some theories suggest migrations over land bridges from Asia during the Ice Age.
Native American creation myths contrast sharply with the scientific narrative, leading to conflicting histories.
- Example: A Dakota Sioux individual's perspective emphasizes the possibility of an indigenous origin contrary to the scientific consensus.

Civilizations such as Cahokia existed in America, housing about 30,000 to 40,000 people with structured societal organization.
Cahokia traded widely, illustrating advanced socio-economic structures similar to those in Europe.
Reasons for the disappearance of such civilizations remain speculative, with theories including environmental changes and disease playing significant roles.

Current society is criticized for leaving little tangible evidence of cultural heritage compared to ancient civilizations, which documented their existence through carvings and written text.
- The reliance on technology and digital media raises concerns about the longevity of such records.

Examples such as the Indian Mounds in Georgia offer insights into the spiritual and communal practices of ancient North Americans, yet much about these civilizations remains undocumented.
- Comparison to the practices of the Cherokee and Creek nations which followed.

European settlers often portrayed indigenous peoples as uncivilized.
This misconception stemmed from a lack of understanding due to differences in societal structures (e.g., absence of stone/concrete buildings led Europeans to view America as a wilderness).

Focus on the Olmecs as one of the earliest civilizations in Central and South America predating the Mayans and Aztecs.
- Their contributions and the discovery of their artifacts through excavations link them to modern understandings of history.
The Mayans and Aztecs were well-known for their intricate cultures and advancements, such as a complex calendar system and agricultural methods.
- The Mayan calendar ceased in 2012 and gained notoriety for its association with end-of-the-world predictions.
- Religious practices included human sacrifices believed to appease deities, emphasizing the civilization's connection between religion and agriculture.

An overview of the Inca civilization with reference to Machu Picchu, which served unknown purposes (e.g., safe retreats).
- The Inca communicated through a unique system involving knots (quipu) rather than a written language.

Emphasis on the Aztec civilization as pivotal, with its capital modern-day Mexico City being notable for its advanced architecture and sanitation.
- The Aztec brutality in conquests generated numerous enemies.
European colonization led to rapid decline due to diseases and warfare.
- The Aztec religious practices included frequent human sacrifices to maintain cosmic order.

The Vikings reached North America but did not establish long-term settlements due to lack of resources.
- Their exploration is often overlooked due to the absence of documented evidence.
Evidence exists of African trade connections with South America predating Columbus.

The historical context of Europe during the medieval period and its transition out of the Dark Ages.
- Following the fall of Rome, Europe descended into a feudal system with the Catholic Church dominating social order.
- The map of Mundi illustrated a worldview centered on Jerusalem, reflecting religious dominance but a lack of geographical knowledge.
The Bubonic Plague radically shifted population structures and initiated socio-economic changes post-crisis.
Initiatives for exploration and expansion commenced due to increased population pressures, national pride (glory), wealth acquisition (gold), and religious missions (God).

Marco Polo's accounts of his travels ignited interest in the broader world.
- His writings became widely published due to the printing press, influencing European perspectives on trade routes and aspirations for exploration.
An overarching desire emerged to discover quicker trade routes to Asia, leading into the Age of Exploration begin in the late 15th century.
