New developments in all three areas forced him to reconsider these positions in the late 1850s and early 1860s, and became the subject matter for Antiquity of Man.
The section about glaciation integrated continental ice ages into the larger picture of the Quaternary Period that Lyell had built up in his earlier works.
He raised his charges in the pages of the weekly journal The Athenaeum, and pressed them with a vehemence that some of his colleagues found distasteful.
Lyell gradually changed the text of Antiquity of Man to blunt some of their criticisms, but throughout the process held that he had been wrongly accused.
His integration of both ice ages and a very old human race into the (geologically) recent history of the Earth was novel for its time, as was his presentation of archaeological data that from continental Europe.
