Charles Lyell

Sir Charles Lyell (1797–1875) was a Scottish lawyer and geologist. As a close friend of Charles Darwin, Lyell became one of the early promoters of The Theory of Evolution. Lyell is also known for his theory of uniformitarianism.

Lyell wrote the "Geological Evidences of the Antiquity of Man" to present his theories and evidence for evolution and an old earth. He supported an ice age as part of his theory of an old earth.
