==Evolutionary implications==
Most humans have multiple copies of the regulatory gene sequence for prodynorphin, which is virtually identical among all primates, whereas other [[primate]]s have only a single copy. In addition, most [[Asia]]n populations have two copies of the gene sequence for prodynorphin, whereas [[East Africa]]s, [[Middle East]]erners, and [[Europe]]ans tend to have three repetitions.<ref name="bmcpsychiatry" >{{Citationcite web |url= needed|date= 11 September 2019 |title= Association between prodynorphin gene polymorphisms and opioid dependence susceptibility: a meta-analysis |author= AugustChang-wang 2014}}Wang

The extent of regulatory gene disparities for prodynorphin, between human and primates, has gained the attention of scientists. There are very few genes known to be directly related to mankind's [[speciation]] from other great apes. According to computational biologist researcher Matthew W. Hahn of [[Indiana University (Bloomington)|Indiana University]], "this is the first documented instance of a neural gene that has had its regulation shaped by natural selection during [[human evolution|human origins]]."{{Citation needed|date = August 2014}}
