According to the theory of punctuated equilibrium, occasional asteroid impacts might accelerate the rate of biological evolution by disrupting a planet's environment to the point where species must try new adaptation strategies.

We should think about sustainability as part of a progression of social and cultural change that has gone through a process of punctuated equilibrium with disruptive disasters triggering new waves of sustainability thought and practice.
This line of research stems from punctuated equilibrium models that have their roots in biology (Eldredge & Gould, 1972) and are increasingly being proposed in the organizational sciences (e.
2) We have resisted becoming a participant in such a ratcheting process, by which periods of punctuated equilibrium periodically occur in which the law lurches in the direction favored by Justice Douglas and his philosophical allies, during which new precedents arise bearing little more than a random relationship to the written law, only to be followed by periods of conservative judicial rule in which these new precedents are affirmed in the interests of stare decisis and become a permanent fixture of the law.
While punctuated equilibrium (PE) reflected in the fossil record is a strong negative evidence to the underlying principle of phyletic gradualism (PG) enshrined in the evolutionary theory, the phenomenon of cell-directed mutagenesis challenges another tenet of the theory, namely, the requirement of stochastic mutations produced by extra-cellular agents to create heritable changes in the organism.
The book is sown through with a vocabulary of adaptive organisms, fitness, punctuated equilibrium, replication and other concepts from evolutionary science.

then demonstrates how application of Whitehead's naturalism can overcome these difficulties, providing a rationale for, and an understanding of, the emergence of higher-level actualities and the theory of punctuated equilibrium.
