【申友解析】

正确答案：D

【考点】主动词一致（Consistency） 平衡对称（Parallelism）
1) 主动词一致:本句要注意两处主动词一致，一是The list…has been，二是animals that exhibit
2) either…or…结构要平衡
(A) that指代animals，因此that子句的动词应该用复数； either…or…结构中using the right和left hand不平衡
(B) exhibits使用错误导致主动词不一致； and includes和has been平衡，共同作为The list的动词。则该句子可化为The list… has been expanded the lower vertebrates和The list… includes the lower vertebrates两个句子，前者明显不通。
(C) either using the right or the left hand结构不平衡
(D) 正确， 注意到了两个地方的主动词一致；the right和the left平衡且使用to include避免了B选项的错误
(E) as表示作为…的意思，后面应该接简单名词； either…or结构不平衡； has been expanded and includes改变了原句的意思
※句子结构: The list of animals that…has been expanded to…
