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

简单来说，进化支学就是按照共同的特点将动物进。

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的唯方法，有种叫做支学的东西。

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人物——使用了种所谓进化支学的方法，把各种布尔吉斯化石进比较。

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

支学源自威利·亨宁 (Willy Henning) 的著作，它根据共同特征对生物体进组，这些特征可直追溯到其共同祖先。
