I’d agree that there is such a split among a lot of people, but that there is also the opinion that a coherent setting and world building can also fit hitting “quota’s” depending on the quota and how you do it.
Tolkiens work is even a good example for this with the dwarfs as the setting and world building never gives a skin tone so it’s easy to have mixed dwarfs rather you want to say there from X clan or even within Y clan they vary. Rop of course fails at this by not having the clan be mixed and instead it’s just a one off.
I don’t know if there are any actual science esc articles about the topic given how rare it is.Also the article is quite weird. Seems almost pseudoscience. Especially the 'lol you can just go tan' section was really off.
It happens and you could likely find an actual report on it but there but I’d bet it’s nearly impossible to find under tabloid stuff. Though Mabye some one better with google could find it easier.
