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…

I believe the pterodactyl, like most (all?) dinos descended from aquatic life forms. Dunno, though.

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?

You know, I’m starting to think that our whole universe is just a cancerous 3+1D polyp on the ass of an entire, proper universe with more dimensions, mass, and energy, and less corruption.

Everything but that last bit, yep. Simulation or unfathomable surreality, same same. Corruption, though, isn’t a thing the universe GAF about. It’s just physics. 🤪

Redwoods are algae???

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.

If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a dinosaur.

“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.

I find pedants are often wrong or completely missing the point.
Sometimes it triggers a fun discussion. and sometimes it’s just tedious.
(
ghoticould never be pronounced like “fish” because “gh” only sounds like an F near the end of a word afterauorou, 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)TheTechnician27@lemmy.world 2 minutes ago

“Humans are viruses” shuld be at the top.

A virus got your “o”.

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.
