The topic of pack behavior and dominance (or alpha) dynamics being debunked came up in another thread (again), and I'd like to take the time to assess the viability of some of the "debunking" claims I keep running across.
First, there's this:
Let's see... where to start?
1) Are the genetic differences between humans and chimps of the same order of magnitude as those between wolves and dogs? Well, chimps and humans have 96% of their DNA in common (ref link), while dogs and wolves share 98.8% (ref link). Close enough, right? Well, 2.8% may seem insignificant, but it does make the above claim mathematically false. Genetically speaking, 2.8% is quite a canyon to bridge. Which leads us to...
2) Dogs and wolves aren't just genetically similar, they are the same species (Canis)! Dogs and wolves can inter-breed, and so can their offspring (one of the tests for species is multi-generational breeding). Can we say the same about chimps and humans? Oops! Nope.
3) As for the 15K years, why not note the evolutionary time distance between chimps and humans? Oh, yeah, because it is several orders of magnitude greater, perhaps? 13 million years, in case you care to count.
4) Not only can dogs and wolves interbreed, but several dog breeds have been generated by bringing wolves into the blood line. That 15K years just got shorter.
5) Finally, do anthropologists study chimps and other primates to understand human behavior? All the time! (ref link) In particular, check out studies of Bonobos (ref link), who are closer genetically to us (98.7% -- ring a bell?).
Associated with this claim are comments about studies of wolf pack behavior in captivity being irrelevant given that wolves interact differently in the wild. Well, that would pass the giggle test if domesticated dogs also lived in the wild, but alas, by definition, they do not!
All of which goes to say, when debunking something scientifically, it helps immensely to get the science straight.
First, there's this:
ref. linkEven though dogs and wolves are genetically similar, they are separated by at least fifteen thousand years of domestication that has changed them in many important ways. Today’s domestic dog is approximately as genetically similar to the wolf as we humans are to chimpanzees.
