The only life forms hardy enough to survive Armageddon, as the old joke goes, will be cockroaches and Keith Richards. But you can add sponges to the list, according to a team of Chinese and British researchers. Not only would they persevere, according to a new study, but they would probably find post cataclysmic conditions ideal and thrive. The theory is based on research the team of palaeontologists carried out at a well preserved fossil site known as the Anji site, on a seabed off the coast of Zhejiang province that originated 444 million years ago, the tail end of what’s known as the Ordovician period, when the planet underwent a mass extinction event that killed off 85 per cent of marine species. But the sponges did “surprisingly” well, the researchers say. “The sponges are often large and structurally complex, and their diversity is equivalent to the total known modern sponge diversity in the richest areas of the Southern Ocean,” the researchers from the Chinese Academy of Sciences and National Museum Wales wrote in a paper published last week in.
