This was a nice, deeper dive into this topic. I'd recently come across the idea the the pack structure with an "alpha" wolf wasn't scientifically accurate while reading "Inside of a Dog"[0]. The book obviously focuses more on things from the dog side, contrasting them with wolves, but did include a brief discussion on the common incorrect thinking of wolf families as being "alpha-dominated packs". It did mention the Mech and Schenkel work, including nothing that Mech was up front and outspoken about the fact that his original published findings on the topic was found to be incorrect.
