　　The relationship between people and dogs is unique. Among domesticated animals, only dogs are capable of performing such a wide variety of roles for humans: herding sheep, sniffing out drugs or explosives and being our beloved companions. It is hard to be precise about when the friendship began, but a reasonable guess is that it has been going strong for more than 20,000 years. In the Chauvet cave in the Ardèche region of France, which contains the earliest known cave paintings, there is a 50-metre trail of footprints made by a boy of about ten alongside those of a large canid that appears to be part-wolf, part-dog. The footprints, which have been dated by soot deposited from the torch the child was carrying, are estimated to be about 26,000 years old.

　　人类与狗狗的关系相当特殊。在家饲的动物中，只有狗狗能胜任如此之多的角色：牧羊犬、缉毒犬、排爆犬、伴侣犬。很难准确的说这种友谊从何时开始的，但是一个合理的猜测是，这种友谊是过去长达2万多年时间以来逐渐加深的。在法国阿尔代什地区的肖维岩洞内，发现的现今所知最早的壁画，一个大约10岁的男孩留下的50米的足迹旁是一串大型半狼半狗的犬科动物足迹。从男孩所举的火把落下的灰烬可推算出，这串足迹距今大约2.6万年了.

　　The first proto-dogs probably remained fairly isolated from each other for several thousand years. As they became progressively more domesticated they moved with people on large-scale migrations, mixing their genes with other similarly domesticated creatures and becoming increasingly dog-like (and less wolf-like) in the process. For John Bradshaw, a biologist who founded the anthrozoology department at the University of Bristol, having some idea about how dogs got to be dogs is the first stage towards gaining a better understanding of what dogs and people mean to each other. Part of his agenda is to explode the many myths about the closeness of dogs to wolves and the mistakes that this has led to, especially in the training of dogs over the past century or so.

　　始祖狗最初都是独来独往的，这一状况维持了数千年。但当它们被逐渐驯化后，跟随人类进行大规模迁徙，使得它们的基因与其它相似的家饲动物的基因发生了融合，渐渐的它们看上去更像狗而非狼了。作为 Bristol 大学的人类与动物关系学系的创始人，生物学家Mr. John Bradshaw认为，要想更好的理解狗狗与人类的关系，首先得具备一些关于狗狗进化的知识。他的一部分工作是探究很多有关狗与狼之间传说中的亲缘关系，及由此产生的各种误解。特别是过去一个世纪以来的狗狗驯化的过程。
