While at the shortest distance scales, most of the sea of quark-antiquark pairs in the proton are the result of gluons splitting into quarks and antiquarks, there is clear evidence for a significant flavor asymmetric and non-perturbative sea, especially at momtentum fraction values around 0.1. This talk will review the evidence for the non-perturbative sea, the possible mechanisms that create it, and the experiments needed to understand its origin including the on-going SeaQuest experiment at FNAL.
