I consider the difference between animals and us as ... don't laugh .. the difference between an 8bit video game and a playstation3/4/5 one. We might have 10, 1000, or 100000x more details but the core ingredients are the same.
Who says that you have more detail. An eagle can see much farther and in more detail than you, and yeah it can fly. A bat has sonar. Some orient by Earths magnetic field which we do not detect. Etc.
It was just an extrapolation regarding brain size. But you're right it's just a napkin theory.
Then compare orca brains to ours. Theirs are larger and more wrinkly.
Yeah but their body is immensely larger, which I assume will require more neurons for basic biological duties. (yet another napkin theory)
