ELI5 why is it that my newborn kitten can learn to use the litter box in a day but my little brother poops in his pants till he is 2?

Because we are human. Humans are smart and we use tools. To use tools we need to walk upright so our hands are free, and to be smart we need big brains. To walk upright we need narrow hips, and to protect a big brain we need big skulls. But the skull of a human child needs to pass through the hips! This conflict of factors pushes human children to be born relatively undeveloped and grow outside of the womb. This is why they are comparatively helpless and incompetent.
