"The Ayla Descent Theory" of Mary Sues
"Children of the Earth," Luis Royo.
After the success of Jean M. Auel's stone age novel Clan of the Cave Bear, there was a very lengthy trend in the publishing world of stone age adventure novels aimed at women that lasted for a decade and only really fizzled out in the early 2000s. After all, "Ayla," the name of the main character of these books, was one of the top baby names of 1987.
The target audience for these books were weird midwestern aunts....you know, the Mists of Avalon and the Mercedes Lackey/Valdemar audience. Therefore, the Clan of the Cave Bear imitators also featured things of interest to the weird aunt audience: Scotland, redhaired women with sharp tongues, commanding wolves, Ireland, Feminism, riding herds of wild horses bareback in scenic locations, Wicca, matriarchial religions, swimming with dolphins....but above all else, American Indians (a culture this audience finds interesting, as anyone who has seen the home decor of a typical weird midwestern aunt can attest), with many novels set in Ice Age America, like Children of the Dawn, Reindeer Moon and the First Americans. Decades later, this audience would form the core fandom for Game of Thrones, and the character of Khaleesi Targaryen in particular.
These books almost assuredly still have a place of honor on the book shelf of the weirdest woman at your job.
Nearly all of these imitators have two of Clan of the Cave Bear's defining traits: 1) a supremely beautiful, usually blonde athletic and statuesque main character over 5'11" who does not realize that she is so beautiful and desirable, who is good at a variety of different skills and is friendly with animals like hawks, dolphins, or horses, and 2) a love triangle between this aforementioned blond but innocent Venus and two bodybuilder muscular he-men cave hunks, one of whom is a blonde guy with long rock star hair (it was the 80s), and the other being a buff black guy with dreadlocks (or otherwise ethnic in some way).
The heroine usually picks the blonde guy in the end, but the audience usually picks the ethnic guy.
In the late 90s and early 2000s, in the broader culture of fandom, it was fashionable to dump on "Mary Sues" (indulgent wish-fulfillment author personas in fanfiction) and the people who wrote them. Accusations of creating a Mary Sue approached a kind of hysteria. Even at the time, when everyone else was getting swept up in this, I thought that getting mad about aunties writing fanfiction showed a loss of perspective, and was a bit silly. Thankfully, we've benefitted from moral evolution: the consensus in fandom now is that writing aspirational characters is a harmless activity that tests a young writer's creative muscles, like the half-Vulcan pretty new ensign on the Enterprise that Kirk and Spock both fall in love with, or a new archer girl who Legolas falls in love with joining the Fellowship. This hate walked hand in hand with insecurities, in the exact same way that people worried about their appearance or concerned with their weight are often cruel to fat people, and there were frequent tests if this or that character in your writing was a Mary Sue.
There was a running joke in this 2000s culture of anti-self insertion called the "Ayla Descent Theory of Mary Sues." The joke was that Mary Sues came into existence because Ayla, the beautiful, athletic heroine of the Clan of the Cave Bear novels, was the ancestor of their entire lineage, as the first known Mary Sue to ever exist in the historical record, described as being a statuesque blonde who did everything right and was always at the center of love triangles, and who changed human history.
According to the running joke, Mary Sues everywhere were descended from Ayla from Clan of the Cave Bear, and she was the first to exist, and Ayla was the explanation of where all the Enterprise's new ensigns main characters fall in love with come from.
