TONNES of "Outlander," British television and The Walking Dead; the occasional love of photography, tennis and food will surface. Oh yeah and movies too. Finally any other topics/current events that are at the fore of my mind/heart.

What’s really cool about this is that cephalopod (octopus, squid, etc.) intelligence evolved completely separately from intelligence in tetrapods (which includes primates, dolphins, crows… basically any other intelligent animals you can think of). Cephalopods are very, very far away from us on the tree of life. For context, you and a starfish are more closely related than you and an octopus. The last common ancestor of humans and cephalopods was the so-called Urbilaterian, the hypothetical first animal with a left-right symmetric body. This animal almost certainly had, at most, an extremely simple nervous system, without anything resembling a brain.

All this is to say that the fact that this octopus appears to be dreaming means one of two things. Either

a) dreaming is a very, very old thing indeed, going directly back to the Urbilaterian. This would mean that almost every animal, from insects to starfish to sea slugs to newts, is likely to have the ability to dream in some capacity or another (unless they have specifically lost it by evolutionary simplification).

or

b) dreaming evolved entirely independently in cephalopods when they developed greater intelligence. This would suggest, at least, that there’s something very fundamental about dreaming related to intelligence itself, which causes it to emerge independently when sufficient intelligence arises.

Needless to say, either of these outcomes would be really very cool.

The more I learn about octopi the more I believe that Hawaiian myth that they’re alien survivors left over from the previous universe.

In my culture, death is not the end. It’s more of a stepping off point. You reach out with both hands to Bast and Sekhmet, they lead you into the green veld where you can run forever.

Remember this viral post? Wanda and Jamal and her husband Lonnie are the most wholesome people, this story brought tears to my eyes originally and I am crying once more learning from Jamal's social media that Lonnie has sadly passed away.

Rest in Peace, Lonnie :(
