I'm looking for the title and author of a story (I think a short story) that I read in the late 1960s or early '70s.
The story was about an ocean planet that has been colonized by space-faring humans. There are no continents, only widely scattered islands. The planet is deficient in metals and far from the main channels of interplanetary commerce. Self-sufficient, the colonists use locally available resources to construct fleets of wooden ships with which they trade between the islands. These ships are powered by "muschines"; non-metallic engines in which huge skeins of in-vitro-grown muscle are harnessed to a crankshaft.
That was the set-up. After a shipwreck, bioengineered muscle cells get loose in the ocean and begin to multiply and evolve. I don't recall how this turned out.
I remembered this story the other day while reading in the newspaper about in-vitro chicken muscle that is being developed to be sold as a meat substitute. Does anyone know the author and title?
