Pratidhvani

A pratidhvani (from the extinct Earth language Sanskrit प्रतिध्वनि pratidhvani "echo, reverberation") is a synthetic organism made to replicate its organic counterpart in nearly all aspects. This includes tissue, organs, cognitive function, and everything else that constitutes a living being. This technology was pioneered by the Elmians during the Early Noŋŋo eon, succesfully creating the first pratidhvani in 4250 ENE, a living replica of a female Earth cat which they subsequently named Prithvi after the Hindu goddess of the earth.

Pratidhvanayah (as they are referred to in the plural) are distinguished from clones in that they possess no imago, i.e. an organism whose genetic material is being sampled, and from other types of yantra (mechanical being) in that its constituent parts are ultimately of organic origin.
