Mass extinctions and expansions | Introduction to Earth systems | meriSTEM

Tharika Liyanage from the Australian National University (anu.edu.au) describes the theory behind mass species extinctions and evolutionary expansions. This as part of a series of educational videos on mass extinctions and expansions.

This clip has been created by the Research School of Earth Sciences (rses.anu.edu.au). These resources are part of a comprehensive program, curriculum matched to the unit 'Introduction to Earth systems'.

This video touches on the following curriculum descriptors:
The diversification and proliferation of living organisms over time (for example, increases in marine animals in the Cambrian), and the catastrophic collapse of ecosystems (for example, the mass extinction event at the end of the Cretaceous) can be inferred from the fossil record (ACSES029)
