Thanks killer whale moms 😭

I can only imagine what goes into the development of an intelligent creature made of tens of quadrillions of cells. Human brains don't stop developing in really major ways until we're 25ish, and there's far fewer cells that need to get situated and settled in a human brain, even if our brain wrinkles are neater.
