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

简单，化分支学就是按照共同的特点将动行分类。

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

但这并不是对生行分类的唯方法，还有种叫做分支学的东西。

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·布里格斯——古尔德书里的另位重要——用了种所谓化分支学的方法，把各种布尔吉斯化石行比较。

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) 的著作，它根据共同特征对生体行分组，这些特征可直追溯到其共同祖先。
