Reverend Ernest Matthews was turned into an ape by Josiah Samuel Smith because he didn't believe that man evolved from apes. (DW: Ghost Light) This sentiment was not shared by the Silurians, who had witnessed the evolution, and therefore frequently called humans "apes". (DWM: Twilight of the Silurians, DWM: Doctor Who and the Silurians, Cold Blood, and many others)

A species of ape known as "Ice Apes" lived under the Antarctic ice cap. (TVC: Ice Cap Terror)
