(The principle of superposition was recognized as early as 1669 by Steno.) Reverend Benjamin Richardson and Reverend Joseph Townsend were a couple of early geologists involved in this work. Obviously, even Lyell was not pushing evolution at the time.
It's just one of the tricks that have been used to make the work a little more precise. I believe he has confused the use of index fossils with evolution.
