This would exemplify genetic drift. But ANIMALS 24-7 has pointed out for more than 25 years that Serpell’s behavioral work started out by barking up the wrong tree. “Heat map,” adapted from 78-breed chart in “Highly heritable and functionally relevant breed differences in dog behavior,” shows relative intensity of traits among 28 medium-to-large dog breeds. “We found high levels of among-breed heritability for 14 behavioral traits,” MacLean, Snyder-Mackler, vonHoldt and Serpell wrote, in one of their few sentences not stated in technical jargon. “Indeed,” MacLean, Snyder-Mackler, vonHoldt and Serpell found, “the overall patterns of breed differences align closely with genetic clades corresponding to functional breed groups. Pitbulls Will Eventually Turn On Their Owners7. Given the staggering amount of press coverage of Michael Vick's pit bulls, television shows devoted to pit bulls, such as Pit Bulls and Parolees, now in its tenth season, Cesar Millan's Dog Nation, co-branded with a pit bull, and the constant production of "positive pit bull" campaigns on the Internet, it seems unlikely that the average person cannot identify a pit bull.

SEATTLE, Washington––The dogma that dog aggression, especially pit bull aggression, is “all in how you raise them” is again refuted by science, but the average reader will have a hard time deciphering the message from the highly technical report “Highly heritable and functionally relevant breed differences in dog behavior,” published on October 2, 2019 by Proceedings of the Royal Society. Starting the C-BARQ measurement with dogs who are already skewed toward aggression may overlook the difference between how rapidly aggressive dogs become aroused as compared to normal dogs, who are never subjected to behavioral diagnostic questionnaires. Only among pedigree snobs do these distinctions have any meaning. Behavioral data from the total pit bull sample size of 532 would therefore be more representative of pit bull traits than the more limited data from the four “breeds” counted separately––especially when offset by comparison to the data from 392 Rottweilers, a much narrower breed, historically outnumbered by pit bulls in the general dog population by a ratio of four or five to one.
