Onychonycteris known species, hence "Onychonycteris" meaning "clawed bat". The specific epithet is a tribute to the fossil prospector and preparator who discovered it, Bonnie Finney. "Onychonycteris finneyi" was the strongest evidence so far in the debate on whether bats developed echolocation before or after they evolved the ability to fly. "O. finneyi" had well-developed wings, and could clearly fly, but lacked the enlarged cochlea of all extant echolocating bats, closer resembling the old world fruit bats which do not echolocate. This indicates that early bats could fly before they could echolocate. However, an independent evaluation of the "Onychonycteris" reference fossil in
Food waste that is lost during any of the four stages of the food supply chain: (1) producers, (2) processors, (3) retailers, and (4) consumers. Precise definitions are contentious, often defined on a situational basis (as is the case more generally with definitions of waste). Professional bodies, including international organizations, state governments and secretariats may use their own definitions. Definitions of food waste vary, among other things, in what food waste consists of, how it is produced, and where or what it is discarded from or generated by. Definitions also vary because certain groups do not consider (or have traditionally not considered)
