So in Australia, there were also these thylacines.

澳大利亚时也有狼。

But that isn't what makes the thylacine so interesting.

但这并狼如此有趣原因。

In Australia, there were also these thylacines .

在澳大利亚，也有这些狼。

And the wolf-like body of the thylacine?

那么狼身体像狼一样吗？

Unfortunately, local farmers liked their sheep more than the thylacine, and eventually they were hunted to extinction.

幸， 地农民更欢绵羊而狼，最终狼被捕杀殆尽。

The last known thylacine died at a Tasmanian Zoo in 1936.

最后一只狼于1936年在塔斯马尼亚动物园死亡。

In Australia, there were these thylacines. There are these marsupial lions, and I think a big body size would have enabled them to escape predation.

澳大利亚有狼，也有狮，我认为雷鸟巨大体型可以让它们逃脱被捕食命运。

But even though evolution doesn't march toward some ideal form, I've gotta say: thylacines are particularly awesome.

但即使进化并没有朝着某种理想形式发展，我还必须说：狼尤其令人惊叹。

The thylacine is about as distantly related from a wolf or a fox as it can be and still be a mammal.

狼与狼或狐狸亲缘关系尽可能远，但仍属于哺乳动物。

Despite coming from different ancestors, the wolf and thylacine independently evolved this analogous trait: walking on their toes.

GS：尽管来自同祖先，狼和狼却独立进化出了这种类似特征：用脚趾行走。

Analogous similarities are the result of convergent evolution, and one of the most striking examples is in how the wolf and thylacine walk.

类似相似性趋同进化结果，其中最引人注目例子就狼和狼行走方式。

Meet the thylacine, also known as a Tasmanian Wolf, or Tasmanian Tiger, a medium-sized meat-eating mammal that as recently as the early 1900s lived on the island of Tasmania.

我们来了解一下狼， 也称为塔斯马尼亚狼或塔斯马尼亚虎，这一种中型食肉哺乳动物， 20 世纪初还生活在塔斯马尼亚岛上。
