A controversial study has a new spin on the otherworldliness of the octopus
Octopuses are strange, smart creatures that certainly seem alien—what with the tentacles, camouflage, and shape-shifting skills. Still, the idea that they actually came from outer space would seem to fall strictly into the realm of sci-fi; an update of HP Lovecraft’s Cthulhu, say.
But in these interesting times, real life reads like fiction. Recently, a group of 33 scientists worldwide—including molecular immunologist Edward Steele and astrobiologist Chandra Wickramasinghe—published a paper suggesting, in all seriousness, that octopuses may indeed be aliens.
The paper, published in the March issue of the the journal Progress in Biophysics and Molecular Biology, is controversial, obviously, and the vast majority of scientists would disagree. But the paper is still worthy of discussion—for one, as a thought exercise, because outlandish ideas are often initially rejected. And in provoking us with seemingly bizarre theories, it forces us to acknowledge that there are aspects of life on Earth for which classic evolutionary theory as yet has no explanation.

The transformative genes leading from the consensus ancestral nautilus to the common cuttlefish to squid to the common octopus can’t be found in any pre-existing life form, the authors say.
