End-Ordovician Extinction - Occurred approximately 443 million years ago. - Estimated to have wiped out about 85% of marine species. - Major causes: - Global cooling and glaciation. - Drop in sea levels. - Impact: - Collapse of marine communities. - Resetting of evolutionary pathways. 2. Late Devonian Extinction - Happened around 374 million years ago. - Loss of about 75% of species. - Possible 2 causes: - Extensive volcanic activity. - Climate change. - Ocean anoxia (lack of oxygen). - Impact: - Extinction of many reef-building organisms. - Diversification of surviving groups. 3. End-Permian Extinction (The Great Dying) - Occurred approximately 252 million years ago. - The most severe: up to 96% of marine species and 70% of terrestrial vertebrates went extinct. - Causes: - Massive volcanic eruptions (Siberian Traps). - Climate warming. - Ocean acidification. - Anoxia. - Impact: - Loss of nearly all trilobites and many other taxa. - Opening ecological niches for future evolution. 4. End-Triassic Extinction - About 201 million years ago. - About 80% of species lost. - Causes: - Volcanic activity linked to the breakup of Pangaea. - Climate fluctuations. - Impact: - Extinction of many archosaurs. - Rise of dinosaurs. 5. End-Cretaceous Extinction (K-T Event) - Occurred around 66 million years ago. - Approximately 75% of species, including dinosaurs, went extinct. - Causes: - Impact of a large asteroid (Chicxulub crater). - Volcanic activity (Deccan Traps). - Climate change. - Impact: - Mass extinction of dinosaurs. - Rise of mammals. --- Causes and Factors Leading to Mass Extinctions Understanding the causes of mass extinctions is crucial for grasping the dynamics of Earth's biosphere. Pogil activities often guide students to explore these factors through inquiry and analysis. Natural Causes Volcanic Eruptions: Large-scale eruptions release ash and gases, altering climate1. and ocean chemistry. Climate Change: Rapid shifts in temperature and weather patterns can threaten2. species survival. Asteroid and Comet Impacts: Impacts can cause massive wildfires, tsunamis,3. and atmospheric changes. Ocean Anoxia: Lack of oxygen in oceans leads to die-offs of marine life.4. Sea-Level Fluctuations: Changes in sea levels disrupt habitats.5. Human-Induced Causes (for current and future considerations) - Pollution - Habitat destruction - Climate change due to greenhouse gases - Overfishing and overhunting Interactions and Feedback Loops - Multiple causes often interact, amplifying the effects. - For example, volcanic eruptions can lead to climate warming or cooling, depending on 3 gases released. --- Impacts of Mass Extinctions on Earth's Biosphere Mass extinctions are pivotal in shaping the trajectory of life on Earth. They cause widespread biodiversity loss but also open opportunities for new life forms to evolve. Immediate Effects - Rapid decrease in species diversity. - Collapse of existing ecosystems. - Loss of ecological functions such as pollination, predation, and nutrient cycling. Long- Term Effects - Evolutionary bottlenecks leading to reduced genetic diversity. - Extinction of dominant groups, allowing others to diversify. - Formation of new ecosystems and biogeographical patterns. Recovery and Evolution - After each mass extinction, biodiversity gradually recovers. - New species emerge, often filling ecological niches left vacant. - Examples include the rise of mammals after the extinction of dinosaurs. --- Educational Strategies Using Pogil to Study Mass Extinction Implementing pogil activities enhances student understanding of mass extinctions through active participation and inquiry.
