US startup Colossal Biosciences has announced plans to bring woolly mammoths, or animals like them, back from extinction and into the frosty landscape of the Siberian tundra.
Colossal has received US$15 million in initial funds to support research conducted by Hravard genecist George Church, among other work. The proposed project is exciting, with laudable ambitions — but whether it is a practical strategy for conservation remains unclear.
Colossal proposes to use CRISPR gene-editing technology to modify Asian elephant embryos (the mammoth’s closest living relative) so their genomes resemble those of woolly mammoths.
The Asian elephant is an endangered species found across the Indian subcontinent and Southeast Asia.
These embryos could then theoretically develop into elephant-mammoth hybrids (mammophants), with the appearance and behaviour of extinct mammoths. According to Colossal, the ultimate aim is to release herds of these mammophants into the Arctic, where they will fill the ecological niche mammoths once occupied.
