The extent to which a given behavior is controlled by genetic factors can be investigated with a concordance study. Behaviors that appear across all culture suggests an underlying genetic component. Symbolic language may be one of the few aspects of behavior that is uniquely human. Facial expressions are universal fixed action problem, you have no control over it for example, a s(cid:373)ile, you"ll fi(cid:374)d s(cid:373)iles all o(cid:448)er the pla(cid:374)et throughout different cultures.
