Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Octopuses have extraterrestrial origins and did not evolve on Earth?

Partly. A European Commission science news article reports a published paper hypothesizing that octopuses may have originated from the cosmos, while a peer-reviewed molecular-clock study and a book summary place cephalopod origins within Earth's evolutionary history. Both sides are partial: the cosmic-origin item is a hypothesis, and the terrestrial items do not directly address the extraterrestrial claim.
