Salmon Gives Birth To Trout.

Posted by timothy on from the paper-contains-facts dept.

mishmash writes "Researchers in Japan have created trout whose fathers were salmon, 'they implanted tissue from trout embryos into salmon embryos; and when the salmon became adults and mated, they produced trout.' Jurrassic Park just came a step closer. The story is also at Nature, where the scientists actually discuss using the technology for reviving extinct species."

  1. Summary is DUMB, sensationalistic by nusratt · · Score: 4, Informative

    "Jurrassic Park just came a step closer."

    Oh, really?
    The Nature article clearly says at the beginning:
    "The technique involves cells called primordial germ cells (PGCs), which are found in embryos."
    And later:
    "theoretically, even if a species **goes** extinct, we can transplant the cells into a closely related species."

    Where is John Hammond (JPark founder) going to get dino *embryos*?

    And, OTOH, if the "some day" merely refers to using DNA (versus PGCs), then how is this news?

    According to the Nature article, the trout concerned is Oncorhynchus mykiss. The salmon is Oncorhynchus masou. Same genus, different species.
