On July 1, 2020, Caleb Evans Conrath was killed in his home. Caleb was a "people person" and a supportive friend to many, who often had other teenagers over to his house. A few weeks short of Caleb's 18th birthday, Davijon Robinson came for a visit. According to Caleb's mother, there was something "suspicious" about Davijon that day, and within a few minutes she heard an argument and gunshots. In the end, Caleb was hit three times, and his mother was also struck once. Davijon disappeared for 13 months before being found and arrested.

The result of this breeding program conducted over more than 40 generations of silver foxes was a group of friendly, domesticated foxes. These domesticated foxes, which were bred on the basis of a single selection criteria, displayed behavioral, physiological, and anatomical characteristics that were not found in the wild population, or were found in wild foxes but with much lower frequency. One of the reasons that these findings were so compelling was that the criterion used to determine whether an individual fox would be allowed to breed was simply how they reacted upon the approach of a human. Would they back away, hissing and snarling, and try to bite the experimenter? Or would they approach the human and attempt to interact?

The domesticated foxes were more eager to hang out with humans, whimpered to attract attention, and sniffed and licked their caretakers. They wagged their tails when they were happy or excited. (Does that sound at all like your pet dog?) Further, their fear response to new people or objects was reduced, and they were more eager to explore new situations. Many of the domesticated foxes had floppy ears, short or curly tails, extended reproductive seasons, changes in fur coloration, and changes in the shape of their skulls, jaws, and teeth. They also lost their "musky fox smell."

The first physiological change detected was in the hypothalamic-pituitary-adrenal axis. This system is responsible for the control of adrenaline, which is a hormone that is produced in response to stress, and controls fear-related responses. The domesticated foxes had significantly lower adrenaline levels than their undomesticated cousins. The researchers hypothesized if the foxes were not afraid of humans, they would produce less adrenaline around them. This explains the foxes' tameness, but it doesn't account for their changed fur coloration patterns. The scientists initially theorized that adrenaline might share a biochemical pathway with melanin, which controls pigment production in fur. Further research has since supported this initial hypothesis.
