They’re one of the strangest creatures in the animal kingdom, and now a new study suggests that octopuses may in fact be aliens.
The bizarre study, led by researchers from the University of Ruhuna in Sri Lanka, suggests that octopuses may have first come to Earth on board an icy meteor .
In the study, the researchers claim that the Cambrian explosion – a period around 540 million years ago when most modern animals appeared – was the result of an extraterrestrial virus that crashed to Earth in a meteor impact.
In particular, the researchers suggest that fertilised octopus eggs may have been on board the meteor.
Octopuses are complex creatures, with several special adaptations such as camouflage, camera-like eyes and complex nervous system.
These adaptations appeared rapidly, and the researchers suggest that the genes for them may have come from another planet.
In their study, published in Progress in Biophysics and Molecular Biology , the researchers wrote: “It is plausible then to suggest [these traits] seem to be borrowed from a far distant ‘future’ in terms of terrestrial evolution, or more realistically from the cosmos at large.”
But not everyone is so convinced.
Speaking to Live Science , Professor Ken Stedman, a biologist at Portland State University, said: “Many of the claims in this paper are beyond speculative, and not even really looking at the literature."
