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

简单来说，化支学就是按照共同的特点将动物类。

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

但这并不是对生物类的唯方法，还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.

福泰德克·布格斯——古尔德书的另位重要人物——使用了种所谓化支学的方法，把各种布尔吉斯化石比较。

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组，这些特征可直追溯到其共同祖先。
