According to experts, our planet is already experiencing mass extinction. They determined that this is already the sixth mass extinction. By studying fossils of an early Triassic Lystrosaurus, experts have managed to reveal how some beings managed to make it through the disaster. Analysis of the fossils showed that ancient mammals were able to adapt and evolve extremely quickly to drastic climate change as they would reproduce earlier in life, and die younger.

This implies that they must have been breeding when they were still [relatively young] themselves." The authors of this report argue that there is evidence to show that animals have been adapting at a rapid rate to cater to the increasingly harsh environment, such as the cod,
