Our neural networks are heavily biased by our genetics. An unbiased neural network takes hundreds of thousands of instances to reliably train a new pattern, a human child can do it in under 10 in many contexts.
We have many subsystems evolved to produce particular types of actions in particular sorts of contexts.
We learn a lot of motor skills in the womb.
In many different ways, genetically, behaviorally, culturally, we have many ways behaving that we are not necessarily conscious of.
