So in Australia, there were also these thylacines.

澳大利亚当时也有袋狼。

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

但这并不是袋狼如此有趣的原因。

In Australia, there were also these thylacines .

在澳大利亚，也有这些袋狼。

And the wolf-like body of the thylacine?

那么袋狼的身体像狼一样吗？

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

不幸的是， 当地农民更欢绵羊而不是袋狼，最终袋狼被捕杀殆尽。

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

最后一只袋狼于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.

澳大利亚有袋狼，也有袋狮，我认为雷鸟巨大的体型可以让它们逃脱被捕食的命。

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，我还是必须说：袋狼尤其令人惊叹。

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

袋狼与狼或狐狸的亲缘关系尽可能远，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：尽管来自不同的祖先，狼和袋狼却独立进化出了这种类似的特征：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.

类似的相似性是趋同进化的结果，其中最引人注目的例子就是狼和袋狼的行走方式。

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.
