If you believe Pit Bulls are inherently dangerous animals, & you support BSL to ban them

77. Let me throw this out for review.

I have only skimmed it but did find this interesting bit that I think might be destined to rile the discussion even more:

"Common to the origin and development of many breeds is a founder event involving only a few dogs and, thereafter, reproductive dominance by popular sires that conform most closely to the breed standard. These restrictive breeding practices reduce effective population size and increase genetic drift, resulting in the loss of genetic diversity within breeds and allele frequency divergence among them. For example, in a genetic study of 85 breeds, Parker et al. (2004) showed that humans and dogs have similar levels of overall nucleotide diversity, 8 × 10-4, which represent the overall number of nucleotide substitutions per base/pair. However, the variation between dog breeds is much greater than the variation between human populations (27.5% versus 5.4%). Conversely, the degree of genetic homogeneity is much greater within individual dog breeds than within distinct human populations (94.6% versus 72.5%). Furthermore, in some breeds, genetic variation has been additionally reduced by bottlenecks associated with catastrophic events such as war and economic depression, making them analogous to human populations of limited genetic variation used for disease-mapping studies such as the Finns, Icelanders, and Bedouins. As a result, the unique pattern of LD in dogs provides an exceptional opportunity to study complex traits that are relevant to human biology using robust approaches that would not be possible in human populations."

Seems relevant.
