| Crows reach fabulous levels of (animal) intelligence with a brain that is a fraction of the size of the brain of great apes. I wonder what progress has been made in studying the differences in organisation between the two. |

| Bird brains are on 2nm process nodes while mammals are 32nm chips |

| Well, it has been shown that birds have twice the density of neurons to mammals, and their brain is larger as a proportion of body mass: https://www.pnas.org/doi/10.1073/pnas.1517131113 So their brain can be equivalent to a much larger primate. |

| They apparently evolved intelligence separately from mammals: https://www.wired.com/story/intelligence-evolved-at-least-tw... |

| > Crows reach fabulous levels of (animal) intelligence with a brain that is a fraction of the size of the brain of great apes. Crows have a higher raw brain-to-body mass ratio (about 2.7% for ravens) compared to adult humans (about 1.9%), so not exactly surprising they are smart. |

| ▲ | b112 2 hours ago | parent [-] | | While interesting, are the brain cells smaller, scaled down with body size? If not, it's not entirely indicative of an increased brain size compared to humans. | | |
| ▲ | Markoff an hour ago | parent [-] | | my point was their brain is not really a fraction of size when you compare it to their body mass, and anyway bigger brain doesn't really mean smarter animal necessarily, elephants are not that smart, so it's not really about size whether scaled or not | | |
| ▲ | tristanMatthias an hour ago | parent [-] | | Why is the ratio important? Wouldn’t it be what the brain is capable of doing, determined by “wrinkles”? (Apparently the true indicator of intelligence, at least for humans). I’d imagine the bigger the brain in absolute terms, the more wrinkles, but who knows. | | |
| ▲ | b112 an hour ago | parent [-] | | It is indeed determined by wrinkles, so listen to your parents, they have more of them. (Sorry, I'm sorry, please forgive) |
