In response to this comment by @Robert:
Joshua (far more than I, despite my working with GAE for a decade now) was from the start tarred with the dreaded brush of racism at BioLogos . In the first instance, this arose from a simple lack of comprehension of the GAE argument, decrying the possible division of the present human race into Adamic humans and some kind of subhumans who might suffer discrimination. This would presumably come from bands of marauding Christians brandishing copies of Rohde’s Nature paper as clubs.
But of course, the entire theory is about the current genealogical unity of humanity (a requirement of Christian theology) despite the special character (in some way open to discussion) of a recent Adam and Eve. So far the only flag waved for actual non-Adamic humans in our time has come from postulating that Tasmanian aborigines were uniquely isolated when discovered, and so might be seen by some as non-Adamic.
This is entirely academic, as far as the risk of “Non-adamophobia” goes, because it’s likely that the last pure-bred Tasmanian died in 1876. If there happened to be any today, they would be indistinguishable from those having mixed aboriginal and European (and therefore Adamic) ancestry. It’s hard to imagine bands of racist GAE supporters organising DNA testing in order to be able to discriminate against the handful of non-Adamic people they conceived might exist in Tasmania if GAE is wrong!
It’s true that the Tasmanians suffered terribly both from malicious and unintended genocide (and the story is more complex than often described), but not only did that occur a couple of centuries before the GAE hypothesis ever arose, but long after the 1656 non-Adamite theory of La Peyrère had ceased to have any traction on anthropologists or colonial powers. The Tasmanians were abused by those who, presumably, believed they too were children of Adam, probably even uninfluenced by the evolutionary racism of Galton or Haeckel at that early time.
Yet at Peaceful Science yesterday a skeptic (“atheist trending agnostic”) couldn’t resist playing the race card to smear the theory by commenting that in a previous GAE discussion: “some shockingly racist opinions [were] being expressed about non-Adamic humans.”
