"Theory of the Earth, With Proofs and Illustrations, Volume 1 (of 4)" by James Hutton is a geological work published in 1795. This groundbreaking publication laid the foundations for modern geology by demonstrating that Earth results from natural forces operating over immense time spans. Hutton proposed that observable processes today, given enough time, could explain the geological features we see in rocks. His work challenged biblical timelines and introduced uniformitarianism, profoundly influencing later scientists including Charles Lyell and Charles Darwin.
