Some holes in that article.
There's a difference between "our great great grandmother's chickens" , "chickens of a few hundred years ago", and "chickens of 2300 years ago".
 
For a "few hundred years" there are plenty of paintings available.
For great great grandmother, there are photographs!
Even for a couple thousand years ago, there are wall carvings in ancient Egypt and Rome.
 
And it doesn't say anything about other countries.  Some of these breeds from China go back a very long way and are markedly different.   Like the Silkies with the black bones, black skin, odd feathers.
 
It's interesting, but I'd like to know a lot more about what they actually came up with.  Kind of looks like they're still working on it.
 
They've found dinosaurs with feathers!  But the time line there is so extremely long that it's hard to comprehend.  How did "chickens" survive that long in the wild do you suppose, with all the trouble we have keeping them?
