However, this is not behavior. Human babies do not take their first step for a couple of years, but it is not because their genetic code prohibits this behavior, it is because they are not able to due to balance and coordination development. Walking is an ability which human babies do not have. Ability may be genetic, but behavior is not. The argument that abilities control behavior is often given as opposition to the above view of ability vs. behavior.
Many people are better at certain tasks than other.
For example, some are musically inclined while others are mathematical or artistic. As a result, their behaviors and interests will follow these abilities. This is true only to a point. Many may be good at math, but they end up studying English or philosophy. One's behavior is not directly determined by the abilities their genetics endow upon them.
