What if..

I love the rabbit hole you opened in my head, also.

What if the ? created us to do their bidding on land?

I know, ancient alien theorists disagreee.

Is one theory 

Octopus Intelligence Sheds Light on Evolution of Complex Brains  The 42 miRNA families Rajewsky and his team identified are not shared with humans. In fact, the most recent common ancestor of octopuses and humans was a primitive flatworm that lived approximately 750 million years ago. These genes were conserved during the evolution of the octopus, so they are likely to be beneficial. Now the question is exactly what benefits they provide.

What he has learned opens the door to a deeper understanding of miRNA’s role in the development of complex brains. “That is something that has been hypothesized for a long time,” Rajewsky says, and now it is becoming clearer. “It probably says, also, that miRNA is doing something in the brain that we still don’t understand.”

Flatworms Are Oldest Living Ancestors To Those Of Us With Right And Left Sides, Researchers Report In Science  

 

Date:March 22, 1999Source:American Association For The Advancement Of ScienceSummary:A team of scientists from Spain and the UK has determined that a certain curiously primitive group of flatworms are the oldest living ancestors to all "bilateral" animals-that is, those with a right and left side. These worms were previously thought to belong to a much younger group of organisms, and their newfound identity also implies that bilateral organisms began making their debut on Earth earlier than previously thought.
