For centuries, people have been fascinated with Octopuses (not Octopi) and have likened them to aliens. In fact, in H.G. Well’s 1898 sci-fi classic Martians in War of The Worlds, the extra-terrestrial lifeforms are conceived to be eight-tentacled beings with large brains. It turns out the Wells may not have been too far off.

A recent study published in the Progress in Biophysics and Molecular Biology journal asks the question “Was the Cambrian Explosion terrestrial or cosmic?” and the 33 researchers believe the answer is the former and not the latter. The Cambrian Explosion refers to the event that happened 541 million years ago that resulted in “the sudden appearance in the fossil record of complex animals with mineralized skeletal remains.”

One of the authors of the latest study, Chandra Wickramasinghe, has shared his belief in the idea of directed panspermia for years. This means that Wickramasinghe believes that life on Earth began by alien microbes. 32 researchers seem to agree.

The paper states: “The genome of the Octopus shows a staggering level of complexity with 33,000 protein-coding genes more than is present in Homo sapiens.”
