Study Notes
Big History Study Guide
- The universe began 13.8 billion years ago in a split second (Big Bang)
- Simplest atoms (hydrogen and helium) formed and collapsed under intense heat and pressure, creating the first stars.
- The deaths of early stars created the pressure and heat necessary to form new chemical elements.
- Earth formed 4.5 billion years ago, the sun formed from collapsing clouds of dust and gas, and planets formed from colliding matter.
Life
- 3 billion years ago, first life emerged. This was single-celled organisms
- Evolution over time resulted in more complex lifeforms (sea life, amphibians, reptiles, mammals)
Collective Learning
- Early humans developed language, enabling communication across generations
Agriculture
- 12,000 years ago, humans began farming.
Modern Revolution
- The last 300 years have been marked by advancements in technology.
What is a Threshold?
- Ingredients (historical moments) + Goldilocks conditions (ideal conditions) = New thresholds of history
What is an Origin Story?
- A cultural or religious explanation for the origins of the world and life.
Who are the Originators and How Humans Were Formed?
- Various cultures and religions have different origin stories
- Examples include: Chinese (Pan Gu), Greek (Gaia, Prometheus, Athena), Iroquois (Great Turtle), Judeo-Christian (God), Mayan (Plumed Serpent), Zulu (Unveliquangi), and Etai (Abbassi).
Emergence of Life (Darwin)
- Evolution is the theory of natural selection, where small changes during reproduction help creatures survive and pass on their advantageous traits, eventually leading to new species.
Is Evolution Evolving?
- Rapid evolution presents how animals adapt to changing environments (salamanders & moths).
- Rapid evolution is influenced by factors like toxic runoff (salamanders) or darker coloration for camouflage (moths).
- These rapid changes can be apparent in organisms with short lifespans and lots of offspring.
- Rapid evolution can be caused by factors like environmental changes (e.g., climate change).
