Contrary to conventional knowledge, their study suggests that larger extinctions are not always a form of “creative destruction” that allows new organisms to radiate (向周围辐射出去) and evolve. Instead, it suggests that mass extinction is rarely associated with new species of radiation. Dr. Hoyal Cuthill, the lead study author from the University of Essex in the UK and the Tokyo Institute of Technology, said in a statement, “Some of the most challenging things to understand the history of life are the vast timelines involved and the number of species. New machine learning applications can help us understand the information in human-readable form. This means that we can, so to speak, hold the evolution of half a billion years in the palm of our hand and gain new insights from what we see.” They concluded that mass extinction and later radiation were not connected as previously thought. Within 5 percent of the most significant periods of disruption (中断), AI detected “big five mass extinctions, seven more mass extinctions, two mass extinction-radiation events and 15 mass radiations. Most importantly, it discovers that massive radiation and extinction rarely occurred with each other, changing the view that greater extinction leads to a kind of deep cycle-like species radiation of nature. It appears that larger extinctions are certainly not the engine of evolutionary radiation. Take the Cambrian Explosion for example and it was about 41 million years ago when a large group of animals first appeared on the first fossil record and the dawn of a high mobile animal equipped with modern physical features. This new study found that a handful of other notable explosions of biodiversity, including the Cambrian Explosion, usually occurred at a time when they we
