there's a lot of support for the idea that a certain population of wolves fell on hard times or became habituated with feeding off the scraps of humans. the aggressive ones would have to be driven off or killed, but certain individuals (probably based on testosterone levels) were approachable, and served a useful purpose in defend their delicious meat scraps from competing predators, thereby helping to protect the humans.
some russians did a long term study using arctic gray foxes, and by selecting for approachability, they also developed curly tails, spotted coats, doglike floppy ears, and adult vocalizations typical of juveniles in a wild fox population.
they came for the food, they stayed for the friendship.

About once a month at Sigma Xi headquarters, we liven up the lunch hour with an American Scientist Pizza Lunch talk. In these informal lectures, scientists describe new research to nonscientists. The series is light on jargon but heavy on solid science. Each Pizza Lunch offers an in-depth look at its subject, whether it's bedbugs or the smart grid.

JSTOR, the online academic archive, now contains complete back issues of American Scientist from its inception in 1913 (as Sigma Xi Quarterly) through 2005.
The table of contents for each issue is freely available to all users; those with institutional access can read each complete issue.
