Darwin used uniformitarianism and deep geologic time to develop his initial ideas about evolution. Lyell was one of the first to publish a reference to Darwin’s idea of evolution [ 28 ]. The next big advancement, and perhaps the largest in the history of geology, is the theory of plate tectonics and continental drift.
Geology often applies information from physics and chemistry to the natural world, like understanding the physical forces in a landslide or the chemical interaction between water and rocks. The term comes from the Greek word geo, meaning Earth, and logos, meaning to think or reckon with.

This form of dating looks at the context of a fossil or artifact and compares it to the other fossils and biological remains (plant and animal) found in the same stratigraphic layers. For instance, if an artifact is found in the same layer as wooly mammoth remains, you know that it must date to around the last ice age, when wooly mammoths were ...

If a seismic survey is repeated over the same area, this gives another dimension of time. Geologists subdivide stratigraphic columns into formations . A formation is a series of sedimentary beds distinct from other beds above and below and is thick enough to be shown on geological maps.
Jan 23, 2023 · The Fossil Record as Evidence for Evolution. Fossils tell us when organisms lived, as well as provide evidence for the progression and evolution of life on earth over millions of years. Fossils are preserved remains or traces of animals, plants, and other organisms from the past. Fossils range in age from 10,000 to 3.48 billion years old.
