“the profound biological continuity between human and nonhuman animals masks an equally profound discontinuity between human and nonhuman minds” (Penn et al. 2008: 109).
If we take MSR to be evidence for a concept of self, self-awareness, and consciousness, than this would mean that the species mentioned above who pass this test have some form of consciousness. However, there is a lively debate revolving around this contentious issue and it is possible that MSR only requires some form of complex body-concept. This means that MSR might not imply self-consciousness but just the ability to represent “body schemas, rather than cognitive schemas: i.e., awareness of oneself as a physical entity rather than awareness of oneself as a psychological entity” (Gómez 2009: 46).
