狗是人类最好的朋友,我们很多人都与狗生活在一起。目前可以统计的狗的种类大约有400多种,那么狗究竟起源于何处呢?狗为何又是世界上种类最为丰富的哺乳动物呢?这个过程又是怎么发生的呢?本片试图与你一起解答这个谜团。Learn how the domestication of dogs might have taken place, including the theory of biologist Raymond Coppinger that it was the animals themselves - and human trash - that inspired the transformation. The genetic analysis of Peter Savolainen of the Royal Institute of Technology in Sweden has placed the origins of domesticated dogs - and those of the first dog - in East Asia. You'll also discover 14 dog breeds that controversial genetic studies show are the most ancient - and the best living representatives of the ancestors to all living dogs.下载电影就来米诺视频,本站资源均为网络免费资源搜索机器人自动搜索的结果,本站只提供最新电影下载,并不存放任何资源。
