	inspection (e.g., looking behind the mirror), (iii) repetitive mirror-testing
	behavior, and (iv) realization of seeing themselves. Visible marks
	and invisible sham-marks were applied to the elephants' heads to
	test whether they would pass the litmus "mark test" for MSR in which
	an individual spontaneously uses a mirror to touch an otherwise imperceptible
	mark on its own body. Here, we report a successful MSR elephant study
	and report striking parallels in the progression of responses to
	mirrors among apes, dolphins, and elephants. These parallels suggest
	convergent cognitive evolution most likely related to complex sociality
