CALHM1 ion channel mediates purinergic neurotransmission of sweet, bitter and umami tastes.

abstract：:The evolutionary history of extant hominoids (humans and apes) remains poorly understood. The African fossil record during the crucial time period, the Miocene epoch, largely comprises isolated jaws and teeth, and little is known about ape cranial evolution. Here we report on the, to our knowledge, most complete fossi...
