You really think that the 10kg brains of sperm whales are less powerful than our tiny pink 1 kg brains? LJL. We have intergenerational knowledge transfer and tool use, yes which gives us the appearance of being smarter. But I'm talking raw intellectual horsepower. And notice what human do you know that can do three dimensional navigation across massive distances, acoustic modeling of the deep ocean etc. Like they literally dive like two miles deep, ljl at human spatial skills being able to reliably do that, that's why they have IQs that are probably almost immeasurably higher than our own.
