Did Octopuses Come From Outer Space?

A scientific paper, originally published in March, from peer-reviewed journal Progress in Biophysics and Molecular Biology has found its way in this week's news-cycle. The paper, which is co-written by 33 authors including molecular immunologist Edward Steele and astrobiologist Chandra Wickramasinghe, suggests that octopuses could be aliens, adding legitimacy to a belief, which otherwise has been debunked several times in the recent years. An excerpt from the paper, which makes the bold claim: The genetic divergence of Octopus from its ancestral coleoid sub-class is very great ... Its large brain and sophisticated nervous system, camera-like eyes, flexible bodies, instantaneous camouflage via the ability to switch color and shape are just a few of the striking features that appear suddenly on the evolutionary scene. [...] It is plausible then to suggest they [octopuses] seem to be borrowed from a far distant 'future' in terms of terrestrial evolution, or more realistically from the cosmos at large."Ephrat Livni of Quartz questions the basis of the finding: To make matters even more strange, the paper posits that octopuses could have arrived on Earth in "an already coherent group of functioning genes within (say) cryopreserved and matrix protected fertilized octopus eggs." And these eggs might have "arrived in icy bolides several hundred million years ago." The authors admit, though, that "such an extraterrestrial origin...of course, runs counter to the prevailing dominant paradigm." Indeed, few in the scientific community would agree that octopuses come from outer space. But the paper is not just about the provenance of cephalopods. Its proposal that octopuses could be extraterrestrials is just a small part of a much more extensive discussion of a theory called "panspermia," which has its roots in the ideas of ancient Greece. Newsweek spoke with Avi Loeb, the Frank B. Baird Jr. Professor of Science at Harvard University, who told the publication that the paper has raised "an interesting but controversial possibility." However, he added, that it offers no "indisputable proof" that the Cambrian explosion is the result of panspermia. Further reading: Cosmos magazine has outlined some flaws in the assumptions that the authors made in the paper. It has also looked into the background of some of the authors. The magazine also points out that though the paper has made bold claims, it has yet to find support or corroboration from the scientific community. News outlet Live Science has also questioned the findings.
