Yeast Probably Originated in China

This is referring to one species of yeast, whereas yeast in general is many millions of years old. This only applies to what is called the Brewer’s Yeast. Yeast as a kind of organism is at least hundreds of millions of years old. As such the title should include the species name, or common name to make clear the truth of this, and prevent confusion.

Single celled fungi are likely to be older than our current continental arrangement, the title could clarify that yeast had most likely become domesticated in China, maybe around 4,000 ago, from which all modern domesticated yeast may have descended.

It's hard to separate what actually came from China, and what didn't come from China. Not that it isn't obvious (I mean really, you invented the spoon -- also claimed by Korea but whatever -- information overload so they have done themselves a disservice.
