Here is where fiction meets the lab. In real-world genetics, creating a "Species IV" hybrid (like the one in the film) is impossible for three catastrophic reasons:
In biology, the concept of a "Species IV" classification is not official Linnaean taxonomy (where we have Kingdom, Phylum, Class...), but a hypothetical state of intelligence. Scientists like Carl Sagan and E.O. Wilson theorized about the progression of life: species iv
This is a prominent peer-reviewed paper in biological taxonomy titled "Towards a global list of accepted species IV: Overcoming fragmentation in the governance of taxonomic lists". Here is where fiction meets the lab
To understand the weight of a designation like "Species IV," one must first appreciate the difficulty of defining a "species" itself. For decades, the "Biological Species Concept" (BSC)—which defines a species as a group of interbreeding natural populations that are reproductively isolated from other such groups—was the gold standard. However, the BSC falls short when applied to asexual organisms, fossils, or the vast microbial world. Wilson theorized about the progression of life: This
