Except the title is absurd, because “all yeast” predates any conceivable ability to trace its precise origin, and has existed at least as long ago as a time when Asia the continent didn’t exist, but was part of Pangaea. Either it’s talking about Saccharomyces cerevisiae or it’s a joke.
If you or anyone can suggest an accurate, neutral title that is 80 chars or less and preferably uses representative language from the article, we'll happily change it again.
Which was part of the supercontinent Pangea only 250mya, and yeast is probably nearly a billion years old. We’re not even talking about the same crustal surfaces. Given how yeast spreads, what’s the theory for how it was constrained to one small part of a supercontinent?
The article is just awful, and title aside is clearly talking about Saccharomyces cerevisiae, or is just full of shit. The claims of the article make perfect sense for Saccharomyces cerevisiae, which could plausibly have been traced through genetic studies to China. All yeast though? How do you get genetic info from a good sample size over hundreds of millions of years?!
