When hunting, ancient wolves, as they do now, sorted and sifted a herd to ferret out the animal that required the least effort to bring down. After wolves cut that animal from the herd, it would eventually stop and face its attackers. While standing still, it would make an easy target for humans' primitive weapons. A meal was won using the strengths of both predators; the partners shared the spoils.
Humans, say Schleidt and Shalter, also learned from wolves how to improve a herd's health by "eliminating the unfit and keeping away big cats, bears, and hyenas." Thus, wolves may have taught our ancestors animal husbandry.
Eventually, this canid-human relationship evolved into wolves becoming dogs. The commonly held view of that domestication is that humans chose the lazy, opportunistic, outcast-from-the-pack wolves that scavenged at human camps. But Schleidt and Shalter present an alternate - and intriguing - possibility of unrecorded history: "scavenging wolves took the initiative and conned the affluent hunting and gathering humans into sharing their plenty, by pretending to be their obedient servants and hunting companions." In other words, wolves may have chosen and trained us.
