Blue whales and other gigantic whale species have evolved to be so largely because theres no apex predator the size of megalodon in todays ocean. More than 99% of the four billion species that have evolved on Earth are now gone. Meanwhile, new gene-editing tools have been developed and technical barriers to de-extinction are being overcome. But after the animals were returned to a refuge in central Oman in 1982, almost all were wiped out by poachers. Focusing on de-extinction could compromise biodiversity by diverting resources from preserving ecosystems and preventing newer extinctions. Some extinct animals also performed vital services in their ecosystems, which might benefit from their return.
