built into the human genome are non-coding sequences of dna called introns. certain portions of those "non-sense" sequences, remnants of prehistoric retroviruses, have been activated and are translating numerous lpcs (large protein complexes). the activation of sheva and its consequential sudden speciation was postulated to be controlled by a complex genetic network that perceives a need for modification or to be a human adaptive response to overcrowding. the disease, or rather, gene activation, is passed on laterally from male to female as per an std. if impregnated, a woman in her first trimester who has contracted sheva will miscarry a deformed female fetus made of little more than two ovaries. this "first stage fetus" leaves behind a fertilized egg with 52 chromosomes, rather than the typical 46 characteristic of "homo sapiens sapiens".
