I have read under a new species discovery post someone writing “they updated life again!” and I am going to borrow it!

I quite like Kevin de Queiroz’s recent take on the matter, so I will refer you to him. There has been quite a bit of subsequent discussion, some of which I agree with, some of which I think is a bit moronic.

TL;DR: They should be treated as a difference of degree, not of kind, and can conveniently be used to capture the grey zone that we know characterises the incipient stages of speciation.

I’m supposed to be working but instead I’m just people watching at the hospital and observing how rank/career correlates with height and wondering if someone is trying to breed some sort of secret eugenics program


Like the most senior program directors are tall doctors and the healthcare assistants are tiny minority women


When do we get full speciation. Who is behind this

There are probably a lot of species that are just ontogenetic stages of one another. But there are probably a lot that are legitimate! Luckily ontogeny we can determine with histological studies, if we’re able to do them. And stuff like sexual dimorphism we can find by looking at populations and seeing there are two distinct peaks or morphs of differentiation. Since there are ways to determine of things are different sexes of the same species, or different growth stages, a lot of other variation is probably at least somewhat reflective of actual species and diversity. But, when it comes to fragmentary fossils, it gets a bit murkier.

So I’m trying to write something and thus thinking of palisman, going to dump some speculation and thoughts I had related to them (may contradict established lore if I didn’t remember specific details)

I think it’d be very neat if there was a witch out there who carved one to resemble a giraffe, specifically to intimidate others/maybe as some kind of symbol of power. Now idk if doing so would also result in the palisman being hostile towards its owner since giraffe hate witches but still cool to think about.

And if one were to carve their palisman to resemble a witch or a more humanoid figure, would it then be able to talk? Would that even be plausible? What about in the shape of a usually inanimate object (imagine one having a rock shaped palisman and then just having it look like a rock is constantly floating around them)

I wonder where the heck is Owlbert, I don’t recall seeing him in S3E2. I think I’d be cute if he’s just been hiding in Eda’s hair this whole time but I’m worried he got broken, lost, or taken by the collector or something

So we know Palismen can die (rip Flapjack and whoever else got consumed by Belos) but assuming they don’t get killed by an outside force, do they just live on forever? Or their magic (magic in the wood) run out eventually aka die of “old age”? Would be pretty depressing just seeing your owners die time after time again, getting attached to one and moving onto the next.

Online we’ve definitely seen dangerous or stupid trends done by teens and kids, sometimes resulting in a permanent affect. Specifically I’m thinking of people who spontaneously put tatoos on themselves just because, and tatoos in general. Now the boiling ilses has social media…so imagine people making palisman based on trends. Trendy palisman. Designs getting stolen off penstagram. Artist making palisman designs for inspiration and such. I know this wasn’t ever shown in the show but I do love how it shows parallels between the demon and human world (and by that extent our world). And this is one way I could see social media affecting palisman making/creating.

When a palisman is turned into a staff for use, where the HECK does that extra wood come from?? When Luz carved hers she did not carve it with the stick bit on so that confirms they don’t need to have more wood to begin with. Yeah yeah I know ✨magic✨ and all that jazz but how I want to know how it works! Is it magic energy coming around to form the staff, the inside of the existing palisman somehow pouring out to form the staff?

On that vein what happens if someone carves a palisman already on a staff? Is it considered the entire palisman and thus a staff appears next to the staff making it two times as long or would the palisman consider the carved staff portion as a staff?

Since palismen are made of wood- could you still get splinters from them? If Amity were to pet her cat palisman for example, would she have to be careful not to get a sht ton of splinters on her? Or when the palisman are off the staff do they become said animals (not walking wood, ex. again of Ghost, Amity would feel fur when petting her palisman)

Hmm… Well, I think when discussing evolution, it’s good to keep in mind that it is not a process that has a “goal.” Humans are an incredibly unique species; there may not ever be anything quite like us ever again.

There are ecological niches; and convergent evolution happens so often because there is an optimal shape to accomplish that task. A social pursuit predator develops long muzzles, and long legs, so hyenas and dogs look similar even though they’re barely related at all.

And Clan cats are clearly some kind of subspecies of cat that’s finding value in social learning and tool use. If humans were no longer a threat or consideration, and this subspecies kept selecting for traits that value social ability and tool use;

Non-physical changes

  1. Their brains would change.
    I’m not going to say their skull would get larger though; that’s a correlation with species intelligence, but I wouldn’t rule out some other change.
    Feel the back of your skull; that is actually a broken monkey gene at work. OUR brains got larger, but evolution is random change. It’s just as likely their brains just get wrinklier, or some protein mutates and makes their synapses fire faster. But the brain would change somehow. Which leads to,
  2. Their diet would change.
    Brainpower is INTENSE. They would need a lot of food and a more varied diet. for my Clan Culture series I actually gave them a gene that turns their taste for sweetness back on, like lactose tolerance in humans. They may need to eat more fish, or start eating ONLY cooked food to help absorb more nutrients.
  3. Longer lives, longer childhoods, less babies
    Big brains are INTENSE. We are a cocial species– that means we have to LEARN as we grow. We are not like precocial, like baby kittens, who are born knowing how to crawl and hiss. This brain takes massive parental investment, both in the womb and after we’re born.
    Even as adults, we’re constantly learning, improving our skills, teaching what we know to others. It’s not good if your master craftsman dies early or you have generation turnover in less than 5 years.
    And what good is being a social species if there’s no society to support these long, informative childhoods? If you’d waste all that energy pushing out 5 kittens a year only for half of them to die and “waste” so much investment? Smaller litters, longer childhoods.

Physical Changes

  1. Tool Tooth
    Evolution works with what the organism has. Caledonian crows haven’t evolved thumbs just because they use tools; they use their beak and their feet. Clan cats have two paws and a mouth; Hands and a pair of portable scissors. A top-and-bottom pair of teeth might become adapted to be stronger so they stop breaking their teeth while toolmaking.
  2. More dexterous paws
    Specifically, the pad would be LOWER on the paw, leaving a “dip” between the beans and pad. It would be like that dip in your palm; that is an adaptation for tool use. You don’t see that beautiful square-shape in chimpanzees or our relatives. I’d reckon an animal using its hands as toolmakers would develop a shape very similar RIGHT there.
  3. Wrist mobility
    Turn your palm towards the ceiling right now. That movement is called supination. Now flip your hand and aim it towards the ground. That’s pronation. Cats currently can’t move their wrists like that. They would be able to, if the species started adapting towards tool use.
    (Don’t do this if it would hurt your wrist of course!! You get the idea.)
  4. Dewclaw would beef up
    And I say this because every time I see a cat actually needing to manipulate something, the dewclaw is actively used. I think it’s likely that it would slide back down the paw over many generations and become a two-knuckle thumb, but with the claw being permanently extended. Speaking of claws,
  5. Index claw would become long and straighter.
    And it would stick upright like a velociraptor, so that it doesn’t dull over time. A very long index claw would be helpful for fine manipulation. Claws evolved for catching prey but becoming useful for tool use instead is called exaptation, when a structure that evolved for one purpose becomes useful for another.
  6. Tails would become even more expressive.
    Cats do communicate with sound as well; but they say a LOT more with their tails. I think it would actually follow that they would naturally speak a sort of tail-sign, if they were evolving into an extremely social species, especially since they are hunters (and not apex predators at that) and silence is a virtue. To accommodate the complexity of language, that thing would be like a bendy straw.
  7. Tails would have a light tip.
    Because it makes it easier to see. A cat with out a tip is harder to understand when they’re tail-speaking, let ALONE in dark conditions. If it’s not white, any lighter color would start being selected for.

And that’s all I can remember off the top of my head. I’d considered this heavily before but, there you have it.

wow! hello! i’ve never gotten an ask before. hmmm, honestly i can’t say i can confidently answer your question because this is only my fourth semester in college…. but i would like to say most likely that wouldn’t happen. now, the separation of species is kind of a difficult and controversial topic because with new technology and information it’s becoming harder and harder for us to make a clear line as to what defines something as a species. it’s possible that all of these animals are the same species and some sort of weird mutation limits the first two from being able to produce fertile offspring. but to be honest, in biology, the easiest and most logical answer is probably the correct one, and that leads me to say that this isn’t something that would happen. that’s the best answer i can up with for you and i hope that helped! and let me end this by saying that we often think of biology as a hard science, but it is not and things are always changing and often times you don’t get clear yes or no answers like you might want :) but if you would like to respond again i’m interested in knowing if you are referring to something irl or hypothetical?
