Several times in evolutionary history, the arrival of an innovative new evolutionary strategy has lead to a mass extinction followed by a restructuring of biota and new dominant life forms. This may pose an unlikely but possible global catastrophic risk in the future, in which spontaneous evolutionary strategies (like new biochemical pathways or feeding strategies) become wildly successful, and lead to extreme climate change and die-offs. This is also known as a ‘biotic replacement’ hypothesis of extinction events.
