These offspring are termed precocial (hence 'precocious'). Species which produce precocial young are typically herbivores that must grow up quickly to avoid being eaten by predators. Within a few hours of being born, young zebra and wildebeest can run and keep up with the herd.
Yeah and there's another thing with precocial species. Their brains are pretty much hard wired (mostly instinct). Human babies on the other hand have all the brain hardware but its not all wired up yet. This is because the wiring can change depending on the environment. What and how one learns is determined by the surroundings.
Some species have few offspring and invest lots of time nurturing them, ...
The whole thing is a tradeoff. Do you want to reproduce with thousands of offspring which are hard wired but cannot really learn a lot of new things. Or do you want few offspring which require a lot of nurture but can learn and adapt to new surroundings.
