That chance seems pretty slim, and the researchers wrote in the study that they rejected popular claims of present-day survival of C. megalodon.. There are three potential approaches for de-extinction: back-breeding, cloning and genetic engineering. The single rarest animal in the world is the vaquita (Phocoena sinus).

And yet for Greely, as for many others, the very fact that science has advanced to the point that such a spectacular feat is possible is a compelling reason to embrace de-extinction, not to shun it. (a) In back-breeding (i), individuals are selected for breeding based on phenotype. Megalodon bit the tales and fins of its prey instead of biting it directly because it cant penetrate its blubber. When Fernndez-Arias first tried to bring back the bucardo ten years ago, the tools at his disposal were, in hindsight, woefully crude. ROMAN UCHYTEL/Science Photo Library/East News.

Scientists and explorers have been talking for decades about bringing back the mammoth. Scientists are trying to bring back the Tasmanian tiger nearly a century after extinction. In those early days scientists would clone an animal by taking one of its cells and inserting its DNA into an egg that had been emptied of its own genetic material. In fact they will return to the face of the earth in 2050.
