This timeline is a result of exhaustive research including carbon 14 dating, Genetic Algorythms, Consulting with Anthropologists, both Cultural and Biological, Archaeologists, the Museum of Natural History in Chicago, Museum of Natural History-Smithsonian, Genome Complexity Conondrum, and my Yorkies Bailey and Mia.
Do not bother challenging or attempting to find fault with these irrefutable findings.
Additionally, you can certainly attest to the fact that most people who meet your Yorkies say: "Those are not dogs!" This is case in point evidence that Yorkshire Terriers followed a simpler and different evolutionary path than their distant canid cousins (much as some may believe we descended from apes [I don't buy this either])
Enjoy
Samc, Bailey and Mia
