minus-squarephdepressed@sh.itjust.workslinkfedilinkEnglisharrow-up18·2 months agoDucks 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…
minus-squarewyldrstallyns@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up4·2 months agoI believe the pterodactyl, like most (all?) dinos descended from aquatic life forms. Dunno, though.
minus-squarephdepressed@sh.itjust.workslinkfedilinkEnglisharrow-up3·2 months agoYeah, all life from the ocean but its a bit more of a stretch to say pterodactyl are fishes.
minus-squarewyldrstallyns@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up2·2 months agoNo argument there 🤣
minus-squareLemmywinks@lemmy.worldlinkfedilinkEnglisharrow-up2·edit-22 months agoAny scientific definition of ‘fish’ which includes all the things we commonly consider to be fish also includes basically all animal life on earth (including humans and, presumably, pterodactyls). Edit: Though generally this is avoided by declaring that ‘fish’ is not an evolutionary category.
