ABSTRACT
A biological imperative, faced by all creatures, is to survive long enough to reproduce. Because of this, behavior related to survival and reproduction often appears to be built into the organism. That is, organisms come into the world with a range of behavior that aids survival and reproduction. Creatures that fly to avoid predators are likely born with the ability to fly. Thus, flying does not need to be learned; it results from the organism’s species history. The complex array of motor movement and coordination involved in flying could be learned, but it is much more dependable when this behavior is based on genetic endowment.
