1. Human capabilities—intelligence, communication, problem solving, and so on—emerge from each person’s unique synaptic activity overlaid on his or her genetically endowed brain anatomy; nature and nurture are in constant activity together.

The brain can place some limits on learning in the form of genetic brain anomalies in neural wiring or structure, but learning can occur through alternate pathways in the brain (as Nico and Brooke demonstrate). So, there are multiple ways both to teach and to learn a skill, depending on the student.
