Disagreement About Dog Domestication
Conflict among scientists who study it

Research about canine genetics and the domestication of dogs is an exciting area of study with many players, so it should surprise nobody that there is disagreement within the field. Multiple groups of researchers from around the world have compared the genomes of dogs and wolves. While they generally agree about the genetic changes that have produced differences between dogs and wolves, their conclusions about the domestication of dogs vary wildly.

The disagreement concerns fundamental aspects of the evolution of dogs such as where, when and why dogs evolved from wolves. So, the location, the timing, and the reason for domestication that various groups propose are not even close.

One group suggests domestication occurred around 10,000 years ago in the Middle East and that it was the development of agriculture around that time that was the catalyst for domestication. Another group claims that it happened around 32,000 years ago in the south of China and related to scavenging alongside the people living there. A third group narrows the time frame for domestication to between 16,000 and 11,000 years ago, and believes that the wolf population from which dogs arose is extinct, making it hard to determine the location of domestication. This third group believes that dogs became domesticated near hunter-gatherers rather than in the presence of an agrarian society.

Much has been made about the discord among scientists studying the domestication of dogs, but it’s hardly surprising. The cutting edge of science is always marked by strongly held opposing views. In the best situations, the intense disagreement among people working in the same field is a crucial part of making progress. Competing hypotheses are critical for the advancement of science. As people challenge each other’s views, all are spurred to study the subject more deeply and design experiments to investigate that which has been called into question. From the ongoing work, the conflicts are eventually resolved as some ideas fall by the wayside and others gain increased support from new data and discoveries.

Sometimes the conflict is cordial and in other cases, it can be very bitter. At this point, the scientists studying dog domestication say that though there is a certain amount of rivalry, they get along and enjoy talking with each other. That may be harder to maintain as people move to the next phase of research into dog domestication and seek to sequence DNA samples from ancient dogs and wolves. The availability of archaeological bone samples is extremely limited so there will be a lot of competition among scientists for both funding to conduct the research and access to the material necessary to do so.

In other words, we can expect a lot of fights over bones in the near future.
