How is a human more like a chimpanzee than a dinosaur is like a jellyfish?

It is impossible to answer when the genesis of the analogy is not known. I mean, how do you draw "dinosaur" and "jellyfish" together in the first place? If we knew that, if we knew what the analogy was referring to, we might well conclude that the dinosaur is more like the jellyfish than we are to another primate; I doubt it, but it is possible, because in philosophy, every thing is contextual, and you offer no context except an unexplained analogy.|||We're more closely related, genetically. We're built fairly similarly--not on the scale of similarity we use when comparing people, but on the wider-ranging scale we use when comparing, say, all mammals. We're more similar to chimpanzees than we are to zebras. And all of us mammals are more similar to each other than any of us are to dinosaurs or jellyfish.

We're also more like a dinosaur, and dinosaurs were more like us, than dinosaurs were like jellyfish. Dinosaurs were also vertebrates.





There are things we vertebrates are less closely related to than jellyfish. Obviously, we're all less closely related to plants. But trace back the ancestry of both me and the tomatoes I should be out picking, and somewhere way back there you'll find ancestors we have in common.|||A human and chimpanzee come from the same lineage. We have many of the same genes, so we have many similar features, like opposable thumbs. Our skulls are also similarly shaped.





Dinosaurs are nothing like jellyfish.|||Well for one, humans and chimpanzees both have brains. A dinosaur has a brain, but a jellyfish does not.|||98% of our dna is identical to that of monkeys...
