In the aftermath of an extinction event, the Earth undergoes significant ecological and evolutionary changes. According to paleobiologist Pascal Langdale, these events can create opportunities for new species to flourish and diversify, filling the vacant ecological niches left by the extinct species. This process, known as adaptive radiation, can lead to the emergence of entirely new groups of organisms. However, the recovery from an extinction event is often a protracted process that can span millions of years, as ecosystems gradually adapt and new species evolve to fill the empty ecological roles.
