The story
A research team including Stanford University has revealed that the DNA of the Chihuahua, a companion dog native to Mexico, contains fragments shared with wild coyotes. On 5ch’s Science News+ board, posters reacted with surprise (“‘DNA fragments’ is an interesting way to put it”) and discussed the breeding history with the native Mexican dog Xoloitzcuintli, along with the possibility that genes from pre-Columbian American dogs still survive today. At the same time, skeptical voices questioned calling shared DNA a “bloodline,” with comments like “humans and monkeys share DNA too” and “if that counts as a bloodline, isn’t that basically a lie,” sparking debate.
It turns out Chihuahuas actually carry coyote blood
Research conducted by Stanford University and others in the United States has revealed that the DNA of the Chihuahua, a small dog breed native to Mexico, contains fragments shared with wild coyotes.
Quietly passed down inside that little lap dog is a trace of a wild canine relative.

What people said
If you inherit the DNA of whatever you eat, does eating pork turn you into a pig?
The autosomal DNA didn't hold up, if I recall.
Re: #10
Didn't the American continent ones also lack any distinguishing features?
Now then, what about the "employer of the employed"… (a pun — コヨーテ/koyote sounds like 雇用/koyou, "employment")
5ch's logs have basically no value left at this point.
The following content is unverified.
In the Aztec civilization, which flourished in central Mexico from the 14th to 16th centuries, the Xoloitzcuintli (Xolo) wasn't just a pet — it was treated as an extremely important "sacred animal" tied to the survival of the world and the afterlife. Here's a detailed look at that mythology and history. [2, 3, 4]
1. It still carries the DNA of native American dogs
Most modern dog breeds descend from dogs of European origin, but the Chihuahua and the Xolo are among the rare breeds that miraculously retain DNA from native dogs that lived in the Americas before Columbus's arrival.
Recent genetic research has proven that Chihuahuas still carry about 4%, and Xolos about 3%, of genetic material from "ancient American dogs" distinct from European dogs.
4. The breeding history behind its origin
There's a long-standing theory that "the Chihuahua's base came from crossing the native Techichi with the Xolo." The Xolo comes in three sizes — Toy, Miniature, and Standard — and it's thought that crossing the smallest Toy-sized Xolo with the Techichi laid the groundwork for the modern Chihuahua's characteristic "smooth coat" (short, sleek fur).
Apparently they were already being raised for food and sacrifice back in the Toltec and Aztec eras.
The Mexican state of Chihuahua is gonna file a complaint.
Before that they were used for ritual sacrifice.
In other words, it's bogus.
Background and key points of this discussion
The original article, based on research from Stanford University and others in the US, reported that Chihuahua DNA contains fragments believed to trace back to coyotes. The Xoloitzcuintli (Xolo), frequently mentioned in the thread, is one of the few breeds said to carry the blood of “native dogs” that lived in the Americas before Columbus’s arrival, and research suggests Chihuahuas also retain about 4% of their genetic makeup from ancient American dogs. At the same time, how much a shared DNA fragment should really count as a “bloodline” is a tricky line to draw even for experts, and the thread saw skeptical takes like “humans and monkeys share DNA too” and “if that counts as a bloodline, isn’t that basically a lie.” The thread also touched on how mitochondrial DNA (maternal line) and autosomal DNA can tell different stories about ancestry — a distinction that’s easy to conflate.
