We examine the possibility that the observed cosmic-ray protons are of primary extragalactic origin. The presentbar p data are consistent with a primary extragalactic component havingbar p/p≃3.2±0.7 x 10-4 independent of energy. Following the suggestion that most extragalactic cosmic rays are from active galaxies, we propose that most of the observedbar p's are alos from the same sites. This would imply the possibility of destroying the correspondingbar α 'sat the source, thus leading to a flux ratiobar α /α<bar p/p. We further predict an estimate forbar α α∼10-5, within the range of future cosmic-ray detectors. the cosmological implications of this proposal are discussed.
