Challenges and Risks in Bringing Back Extinct Creatures
During the careful 22-month process of examining an Asian elephant, many things could go wrong. Making the correct genetic edits and ensuring the desired physical attributes is challenging. The nuances of somatic cell transfer in different animals add complexity. Surprisingly, xenotransfer, the transplantation between species, is common, like pig tissue in human hearts. Even genetically distant species, such as mammoths and Asian elephants, can produce viable offspring. With a high degree of confidence, interspecies transfer and surrogacy for creating a new species seems plausible. Due to the 22-month gestation period, it is likely that another species will be created eventually.
