Spiders also produce more pound per pound intelligence. They are solitary. What if they became social? Brain-body ratio is provocative, but not the whole story. Seeing galahs (Australian corvid https://wikipedia.org/wiki/Galah) socialize in trees in monkey troop-like fashion, dextrous in tooth and claw, makes me believe they are on the way. Though maybe raccons are next. > efficiency is Good Enough I was thinking that, now I think it may be the niche environment, which we somehow happened to stumble into, giving a more rewarding gradient for intelligence. OTOH, it could have been some neuroanatomy trick, eg faciliating abstraction/hypothesis. IDK. I think it's one of the more fascinating questions of our intelligence, and will be telling. I don't want to harp on this point, but the birds-are-dinosaurs seems a meaningless semantic classification to me, more about our definitions than reality. Like "Pluto, planet?" I mean, why not call mammals a subgroup of reptiles, since we evolved from them? Anyway, I'm sure this debate has raged hotly across the centuries amoungst taxonomic philosophers, and carefully taking into account all the perspectives, they've collectively come up with... something. |
It's a lot more direct than "mammals are a type of reptile".
Particularly because late stage dinosaurs, the theropods, had feathers and generally looked like birds with teeth that can't fly. Some later models could in fact fly.
If you look at this Wikipedia page: https://en.wikipedia.org/wiki/Feathered_dinosaur
You'll see that there is a single step from Velociraptor to Birds.
> The scientific consensus is that birds are a group of theropod dinosaurs that evolved during the Mesozoic Era. A close relationship between birds and dinosaurs was first proposed in the nineteenth century after the discovery of the primitive bird Archaeopteryx in Germany.
It took a lot of steps to go from reptiles to mammals.
