Yeti (Homo correctus) are the ancient ancestors of SubGenii. SubGenii (Homo subgenius) are actually hybrids of purebred Yeti with humans (Homo sapiens), and human-Yeti hybrids are known as Yetinsyny. Almost all SubGenii who exist nowadays are Yetinsyny hybrids. Purebred Yeti can still be found in some remote uninhabited regions of Earth, such as Tibet, the Pacific Northwest, Siberia, Alaska, Canada, and Cleveland Heights, Ohio. They have various other names such as "Bigfoot", "The Abominable Snowman", etc.
J. R. "Bob" Dobbs, unlike most SubGenii, actually has 100% pure Yeti DNA, by some genetic accident or mutation, making him the only known Homo correctus in the Church of the SubGenius.
Originally the Yeti had a vast civilization on the lost continent of Atlantis, the jewel of which was their wondrous capital city of Mutantis, and it was here that humans were created through genetic engineering by Yeti scientists. The Yetinsyny, or SubGenii, came about through the actions of a perverted rogue Yeti scientist who actually mated with the human test subjects, fathering the Yetinsyny half-breeds, the SubGenius race. These offspring brought about the downfall of the great Yeti civilization of Atlantis, and only recently have rediscovered their noble Yeti roots and founded the Church of the SubGenius. While the humans were created by the Yeti and the SubGenii were created by miscegenation between Yeti and humans, the Yeti themselves were a creation of the X-ists, an alien race from Planet X who created the Yeti under orders from Jehovah 1. The final stage of Yeti and human evolution involves the opening of the third nostril through psychic surgery in Dobbstown, Malaysia, at which point SubGenii are transformed into the ultimate, final, most advanced product of Yeti and human evolution: OverMen and UberFemmes (the species Homo excelsior).
While it is true that the Yeti genes within the Subgenius race continue to be watered down through each passing generation, it is also true that advances in genetic science have made it possible to amplify any trace DNA though Reverse Chromosomal Engineering (a common technique used by alien overlords to recreate otherwise lost biogenic treasure). For this reason, any Subgenius with in even a fraction of Yeti DNA will be vacuumed up on Xday and provided automatic transport to Planet X before Earth's demolition. It is a promise referred to in Subgenius scripture as the "Great Harvest" (an esoteric concept explained in graphic detail by Our Legacy of Blood).
Stanisław Szukalski is the human kook who miraculously discovered the existence of Yetinsyny (a.k.a. SubGenii) and started the Forbidden Science of Zermatism. Like fellow kook extraordinaire Francis E. Dec, who also was one of the most brilliant humans of the 20th Century and was likewise a great theorist of Forbidden Science, Stanisław Szukalski was a Polish man who lived in the United States. It seems the people of Poland are especially gifted at Forbidden Science... just imagine how much more progress Forbidden Science would have made if Adolf Hitler had not committed genocide against the people of Poland and if they had not subsequently been oppressed under Communism for many decades, with Forbidden Science forbidden and harshly repressed by the Communist authorities! Here is a video of the art of Stanisław Szukalski (the art mostly depicts Yetis and their Yetinsyny/SubGenius half-breed offspring):
Here is a SubGenius bulldada video that has a real live Yeti excremeditating in it:
