De-Extinction: A Scientist’s Perspective from Inside a Cloning Lab
Chris draws on his PhD-era experience at Texas A&M—including meeting Dewey, the world’s first cloned deer—to unpack de-extinction and why cloning is far harder and less efficient than headlines suggest. He revisits Dolly’s breakthrough, explains somatic cell nuclear transfer, and highlights low success rates and frequent abnormalities. Chris explores the only true de-extinction attempt, the Pyrenean ibex, which survived only minutes, and explains why mammoths and “dire wolves” cannot be truly cloned due to fragmented DNA, with current efforts relying instead on genetic engineering. Chris also outlines major challenges around elephant egg sourcing, embryo transfer, and gestation, questions claims that mammoths could meaningfully impact climate change, and argues conservation resources are better directed toward protecting existing species, while acknowledging potential scientific benefits from the research.
