Earth CAGE Syllabus

summary of the evolutionary history of the Earth

  • Stellar nucleosynthesis added the elemental building blocks of rocky planets and life to the interstellar medium
  • The Sun and planets evolved from a cloud of cold dilute gas and dust
  • The Earth cooled and the iron sank to the core
  • A Mars sized planetesimal struck Earth resulting in the formation of the Moon
  • The Earth cooled and the land, oceans, and atmosphere evolved along with life

solid Earth and Moon

The solid Earth and its Moon co-evolved following a giant planet impact that turned Earth into a donut shaped synestia which condensed into the Earth and its exceptional Moon. The Moon receded over time due to tidal interactions, but its tidal influence on Earth may have been critical to the origin of life on Earth.

climate of Venus and Earth

The extremely high surface temperature of Venus is the same from its Equator to its poles and throughout its 1400 hour night. Earth’s atmosphere and climate evolved due to sunlight, the influence of oceans, biological and biogeochemical processes, and interior outgassing. The tilt of the Earth’s axis of rotation is critical to providing a stable habitat for life on Earth.

molecules of life and metabolism

Molecules and metabolism are the building blocks of life. Organic molecules that form in space are transported to planets by meteorites. Sunlight, thermal energy sources, and water cycles enable building blocks to evolve. Prebiotic building blocks of life form and evolve into proto-cells due to biogeochemical processes. Single celled organisms diversify and evolve due to genetic variations and natural selections. Molecules, metabolisms, and membranes diversify and evolve. Complex cells form and evolve into complex organisms due to endosymbiosis and other relationships.

geobiosphere

The geobiosphere evolves due to biological and biogeochemical processes. Earth and life evolve due to extraterrestrial impacts, interior outflows of energy and matter that cause volcanoes and earthquakes, sunlight, weathering by atmosphere, hydrosphere, and biogeochemical processes. Microbial ecosystems co-evolve with Earth’s oceans and atmospheres.

biological and artificial intelligence

Biological and artificial intelligence evolve, possibly along with consciousness and free will. Cells respond to chemical stimuli and then to the flow of charged particles leading to neurons and biological neural networks, sensory inputs, big brains, tool use, and artificial intelligence.
