    My attempt at an explanation

    • Ducks are dinosaurs: Ducks, as with all birds, evolved from theropods and are considered living dinosaurs.

    • Horses walk on middle fingers: Ancestors of modern horses have 5 toes the size of a small dog. Eventually they evolved away the other toes and only the middle toe remain.

    • Bees are crustaceans: Crustacea is not a single branch in the tree of life but a collection of multiple branches (i.e. paraphyletic). If we pick a point and said everything after that is considered the same group, then by necessity we have to put bees (and all hexapoda) and what we traditionally call crustaceans into a single group. That group would be pancrustacea. Is that exactly the same as saying bees are crustaceans? Are jackdaws crows? I'll let you decide.

    • Pterodactyls are fish: Fish is also not a single branch. By the same token, if we want to put what we traditionally counted as fish (such as sharks, carps, and lungfishes) together as a single group, we have to include all vertebrates (which includes pterodactyls, us, whales, etc.)

    • Redwood are algae: I'm not too sure about this one. The wikipedia page for algae say that it excludes the land plants (embryophytes) which redwoods are part of.

    • Humans are part virus: Viruses have the ability inject and splice their genetic material into our genome and have our cells do the cloning for them. Usually it is not passed on to the next generation. Apparently an ancient strain of virus from millions of years ago incorporated themselves into our genome and our germ cells (sperm and egg) and can be passed on to the next generation.

        The latest puzzle: what the viroids doin’ in our guts? Nobody knows, we are only just realised they are widespread and not exclusive to flowers or whatever Anton told me. Tiny simple RNA smudges that are too simple to even qualify as a virus.

        I feel like they’re as close to abiogenesis as we’ll ever get, with these living fossils.

      “Redwood are algae” is a similar statement to “Pterodactyls are fish” or “bees are crustaceans”. Redwoods are land plants, thus are also members of Viridiplantae - the clade containing land plants and green algae. The sister taxa to Viridiplantae in clade Archaeplastidia are Glaucophyta (unicellular algae), and Rhodaria (contains red algae among other things). Thus since land plants are more closely related to green algae than green algae is to red algae or glaucophytes, if we want to treat the term “algae” as a monophyletic clade, then we have to include land plants in that, which of course includes redwoods.

      It could explain why some people suffer emotional distress while under antibiotics (I get severe depression).

      More than 90% of the serotonin in your body is produced in your gut in a process that is regulated by bacteria. This serotonin not only aids in digestion, but interacts with nerves that communicate with the central nervous system to alter mood and mental health

      If you experience severe depression under antibiotics, you might try to take some probiotic supplements that have strains including Lactobacillus and Streptococcus along with a helping of some soluble fiber.

        The serotonin in your gut can’t pass through the gut-blood barrier, and therefore never reaches your brain, so it has no effect whatsoever on your ability to feel happy.

        Unripe bananas are full of serotonin (which breaks down to melotonin as they ripen), but the only effect that has on your body is to give you diarrhoea.

      Here’s my out-there take on consciousness:
      Picture a surface of incredibly high but stable energies, like the one on a pulsar. Now imagine that those energies manage to shake a fundamental consciousness field hard enough at a large enough scale, that virtual consciousness and anti-consciousness pairs constantly bubble in and out of existence.

      Ducks are avians, thus descended from dinosaurs.

      Anatomically, the hoof of a horse is equivalent to a human middle fingernail.

      There are “sea bees” tiny crustaceans that are pollinators of underwater plants. Both crustaceans and “bugs” are arthropods.

      Not sure about the pterodactyl fish reference.

      Redwoods and all plants really descend from photosynthetic algae.

      About 8% of the human genome is composed of ancient viral DNA from viruses that integrated into DNA…

      It’s cladistics.

      “Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms worms or fishes were used within a strict cladistic framework, these terms would include humans.”

        so basically it’s a language problem, not a biology problem? people are incorrectly assuming that any group of species with a word to describe it must be monophyletic, and therefore include all unrelated species which would make it monophyletic?

      Yeahhh, I looked it up and I don’t know what OP meant. there are redwood lichen who live symbiotically with the trees but are separate life forms.

      Then there’s the “redwoods of the sea” huge kelp like algae structures that resemble tree growth patterns but… like aren’t the actual redwood trees.

      soooo yeah. I dunno.

      it depends on how you define algae. different authors use different conventions.

      sometimes: algae = the set of all organisms that live in water and do photosynthesis

      sometimes: algae = the set of all cyanobacteria

      these are not the same groups.

  • TheTechnician27@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

    “Pterodactyls are fish” seems disingenuous to insert when two of the previous ones are about pedantic taxonomy facts (which are true). “Fish” are paraphyletic and thus not an actual taxon, but as a practical group, it’s all non-tetrapod vertebrates – and order Pterosauria are decidedly tetrapods.

    source
    • bisby@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

      I find pedants are often wrong or completely missing the point.

      Sometimes it triggers a fun discussion. and sometimes it’s just tedious.

      (ghoti could never be pronounced like “fish” because “gh” only sounds like an F near the end of a word after au or ou, but ghoti is at least an interesting way to bring up the topic of weird inconsistencies of the english language, even if it’s wrong)

      It is not a “sister” group because some crustaceans are more related to insects than to other crustaceans; check the family trees here. The accurate way to say this is that Hexapoda is clade within Pancrustacea, and that “crustaceans” is a paraphyletic group composed of all Pancrustacea minus the ones belonging to Hexapoda.
