Is hand eye coordination hard wired into us or is it something that develops over time?

For people - it's both. You start off just kind of flailing your limbs when you're a newborn and don't have the muscle anyway to do that much. Pretty quickly the figure out getting their hand to their face without just smacking themselves. However, that's not relaly "hand eye" coordination so much as knowing where your own body is. As the kid gets older they will start batting at stuff to practice, and it takes some time to get down.

This is really helpful, evolutionarily. We sort of have a baseline coordination we're born with that our body fine tunes as it grows. If it was completely hard wired, if we didn't grow at the exact right speed and way, our coordination would fail us. The soft approach means we can learn to adjust, which is helpful if we're injured. It also lets us focus on certain skills. An expert marksman might not be as skillful at playing the piano.
