In simple terms, cladistics consists of organizing organisms on the basis of shared features.

简单来说，进化分支学就是按照共点将动物进行分类。

But that isn't the only way to classify creatures, there's also a thing called cladistics.

但这并不是对生物进行分类唯方法，还有种叫做分支学东西。

Fortey and Derek Briggs-one of the other principals in Gould's book-used a method known as cladistics to compare the various Burgess fossils.

福泰和德里克·布里格——德书里另位重要人物——使用了种所谓进化分支学方法，把各种布吉化石进行比较。

Derived from the works of Willy Henning, cladistics groups organisms by common characteristics traced all the way back to their common ancestor.

分支学源自威利·亨宁 (Willy Henning) 著作，它根据共征对生物体进行分组，这些征可直追溯到其共祖先。
