Course Modules Structure

• The course will focus on three modules beginning with the history of life on Earth.

• A breakout group activity: Identify three critical moments in Earth's life history.

• Engage in discussions about significant events:

  • Mass extinctions, the oxygen revolution, formation of Pangaea, and more.

Critical Moments in the History of Life

• Key historical events identified by students:

  • Mass Extinction: A significant event with implications for species evolution.

  • Oxygen Revolution: Transition marked by the emergence of cyanobacteria.

  • Formation of Pangaea: Implications for Earth’s geological and biological changes.

  • Cambrian Explosion: A period of significant diversification of life forms.

  • Cretaceous Extinction: Notable extinction event, impacting dinosaurs.

  • Evolution of Eukaryotes: Critical for the emergence of complex life forms.

  • Human Civilization Development: How interactions with biology and environment evolved.

Geology and Biology Connection

• Discussion about the relevance of geology to understanding biological history.

• Importance of geological exercises to understand the EarthViewer and historical timelines.

EarthViewer Exploration

• Engagement with EarthViewer for examining historical geological events:

  • Students explore specific moments and their significance.

  • Exploration of Earth’s structure, plate tectonics, and chemical evolution over time.

  • Key geological milestones and their contributions to biological evolution.

Geological Time Scale

• Key Eons discussed:

  • Hadean Eon: No life present.

  • Archaean Eon: First living organisms.

  • Proterozoic Eon: Introduction of multicellular life and eukaryotes.

  • Phanerozoic Eon: Marked by major evolutions including the Cambrian period.

Taxonomy Structure

• Overview of the classification system of living organisms.

• Introduction of Carl Linnaeus and the binomial nomenclature system:

  • Genus and species components, written in italics or underlined.

• Discussion about the modern three-domain model and distinctions between prokaryotic and eukaryotic domains.

• Phylogenetic trees as tools for visualizing evolutionary relationships.

  • Basic concepts including nodes and common ancestors.

Academic Support and Resources

• Emphasis on the importance of understanding concepts and terminology to succeed in biology courses.

• Continuous support from the professor to clarify any uncertainties regarding course materials.
