exogeened

Exogeened is a term used in speculative fiction and certain theoretical discussions to describe something that has been genetically engineered or altered by extraterrestrial intelligence. It suggests an origin of genetic manipulation that is not of Earthly, human, or natural terrestrial processes. The concept often arises in discussions about the origin of life on Earth, the possibility of ancient alien intervention, or in the creation of fictional alien species or bio-engineered organisms within a narrative.

The term "exogeened" is a portmanteau of "exo," meaning "outside" or "external," and "geened," a shortened form of "genetically engineered." It implies a deliberate and artificial modification of genetic material, with the "exo" prefix specifically pointing to an alien source for this modification. This contrasts with natural evolution or human-directed genetic engineering.

While the term is primarily found in fictional contexts, it can also touch upon fringe scientific theories or philosophical questions regarding the possibility of panspermia where life, or its precursors, may have originated elsewhere and been introduced to Earth, or more specifically, that the genetic makeup of terrestrial life itself might have been influenced by non-terrestrial agents. However, there is no scientific evidence to support the existence of exogeened life on Earth. The concept remains firmly within the realm of speculation and storytelling.
