Principles of Geology: Being an Attempt to Explain the Former Changes of the Earth's Surface, by Reference to Causes Now in Operation is a book by the Scottish geologist Charles Lyell that was first published in 3 volumes from 1830 to 1833. Lyell used the theory of uniformitarianism to describe how the Earth's surface was changing over time. [3]
Lyell and Hooker were instrumental in arranging the peaceful co-publication of the theory of natural selection by Darwin and Alfred Russel Wallace in 1858: each had arrived at the theory independently. Lyell's views on gradual change and the power of a long time scale were important because Darwin thought that populations of an organism changed ...
Hutton's Unconformity at Jedburgh. Above: John Clerk of Eldin's 1787 illustration. Below: 2003 photograph. Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle, [1] is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the ...
In the natural sciences, gradualism is the theory which holds that profound change is the cumulative product of slow but continuous processes, often contrasted with catastrophism. The theory was proposed in 1795 by James Hutton, a Scottish geologist, and was later incorporated into Charles Lyell's theory of uniformitarianism.
Time's Arrow, Time's Cycle: Myth and Metaphor in the Discovery of Geological Time is a 1987 history of geology by the paleontologist Stephen Jay Gould, in which the author offers a historical account of the conceptualization of Deep Time and uniformitarianism using the works of the English theologian Thomas Burnet, and the Scottish geologists James Hutton and Charles Lyell.
Lyell provided evidence for Uniformitarianism, a geological doctrine holding that processes occur at the same rates in the present as they did in the past and account for all of the Earth's geological features. [29] Lyell's works were popular and widely read, and the concept of Uniformitarianism took a strong hold in geological society. [24]
The geologist Charles Lyell invited Darwin to dinner on 29 October 1836. Over dinner Lyell listened eagerly to Darwin's stories (which supported Lyell's uniformitarianism) and introduced him to Richard Owen and William Broderip, Tories who had just been involved in voting Grant out of a position at the Zoological Society. Owen was rapidly ...
This idea, uniformitarianism, was used by Charles Lyell in his work, and Lyell's textbook was an important influence on Charles Darwin. The work was first published in 1788 [4] by the Royal Society of Edinburgh, and later in 1795 as two book volumes. [5] [6]
