Why are humans utterly helpless at birth, but many species of animal already know what to do.
Because we're born earlier in the gestation process than some animals due to our larger brain/head size and bipedal body shape. If we stayed in long enough to be able to do things, we'd rip our mothers apart on the way out. And, as said below, even newborn infants 'know' to seek food and warmth.
