Who introduced uniformitarianism?
Coined by William Whewell, it was originally proposed in contrast to catastrophism by British naturalists in the late 18th century, starting with the work of the geologist James Hutton in his many books including Theory of the Earth.
When was uniformitarianism introduced?
In 1785, Scottish geologist James Hutton (1726–1797) electrified the geologic community when he presented a theory on the formation of Earth that contradicted the Bible-based one. The major elements contained in his Theory of the Earth were later termed "uniformitarianism." Hutton maintained that: 1.
What did James Hutton discover?
Lived 1726 – 1797. James Hutton transformed our concepts of the earth and the universe by deciphering the message carried by common rocks. He discovered that our planet is enormously older than people believed. He gathered evidence with his own eyes rather than relying on what 'everyone knows' or the written word.
What was James Hutton’s theory?
Hutton proposed that the interior of the Earth was hot, and that this heat was the engine which drove the creation of new rock: land was eroded by air and water and deposited as layers in the sea; heat then consolidated the sediment into stone, and uplifted it into new lands.
Who wrote Principles of Geology and emphasized the principle of uniformitarianism?
James Hutton. He is best known as the author of Principles of Geology (1830–33) which presented to a wide public audience the idea that the earth was shaped by the same natural processes still in operation today operating at similar intensities.
How did James Hutton help Darwin?
It was Lyell's book, but Hutton's ideas, that inspired Darwin to incorporate the concept of an "ancient" mechanism that had been at work since the beginning of the Earth in his own world-changing book, "The Origin of the Species." Thus, Hutton's concepts indirectly sparked the idea of natural selection for Darwin.
What did James Hutton prove?
Hutton's contributions Hutton showed that Earth had a long history that could be interpreted in terms of processes observed in the present. He showed, for instance, how soils were formed by the weathering of rocks and how layers of sediment accumulated on Earth's surface.
Who is James Hutton and what’s his contribution?
James Hutton (1726 – 1797) is best known for his important contributions to the science of geology (uniformitarianism and the great age of the earth). However, Hutton was also the first person to propose a mechanism of natural selection to account for evolutionary change over time.
Who is known as the author of Principles of Geology?
geologist Charles Lyell 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 1830–1833.
Who is James Hutton and what did he do?
James Hutton was a Scottish geologist, chemist, naturalist, and originator of one of the fundamental principles of geology—uniformitarianism, which explains the features of Earth's crust by means of natural processes over geologic time.
What theory did James Hutton develop?
James Hutton. Along with Charles Lyell, James Hutton developed the concept of uniformitarianism. He believed Earth's landscapes like mountains and oceans formed over long period of time through gradual processes.
How did Lyell and Hutton influence Darwin?
Thereof, how did Lyell and Hutton influence Darwin? They proposed that geologic events in the past were caused by the same processes operating today, at the same gradual rate. He was a close friend of Charles Darwin, and contributed significantly to Darwin's thinking on the processes involved in evolution.
What did Alfred Wegener discover?
Alfred Lothar Wegener Wegener was a German meteorologist, geophysicist and polar researcher. In 1915 he published 'The Origin of Continents and Oceans', which outlined his theory of Continental Drift.
What is James Hutton famous for?
James Hutton (1726–1797), a Scottish farmer and naturalist, is known as the founder of modern geology. He was a great observer of the world around him. More importantly, he made carefully reasoned geological arguments.
What did Hutton and Lyell determine?
Hutton and Lyell concluded that the Earth is extremely old and that the processes that changed the Earth in the past were the same processes that operate in the present.
What did Erasmus Darwin discover?
Erasmus Darwin was a respected physician, a well known poet, philosopher, botanist, and naturalist. As a naturalist, he formulated one of the first formal theories on evolution in Zoonomia, or, The Laws of Organic Life (1794-1796).
Who introduced continental theory?
scientist Alfred Wegener The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other.
What did Harry Hess discover?
Harry Hess was a geologist and Navy submarine commander during World War II. Part of his mission had been to study the deepest parts of the ocean floor. In 1946 he had discovered that hundreds of flat-topped mountains, perhaps sunken islands, shape the Pacific floor.
What is Charles Lyell’s theory?
Lyell argued that the formation of Earth's crust took place through countless small changes occurring over vast periods of time, all according to known natural laws. His "uniformitarian" proposal was that the forces molding the planet today have operated continuously throughout its history.
Who is Erasmus Darwin how did Erasmus contribute to the theory of evolution?
Erasmus Darwin was a respected physician, a well known poet, philosopher, botanist, and naturalist. As a naturalist, he formulated one of the first formal theories on evolution in Zoonomia, or, The Laws of Organic Life (1794-1796).
What did Erasmus Darwin say?
In his Phytologia (1800), Erasmus Darwin described the “muscles, nerves and brains of vegetables,” concluding that plants have sensations and volition, “though in a much inferior degree than even the cold-blooded animals” (133).
How did Alfred Wegener discover continental drift?
Wegener noticed the similarity in the coastlines of eastern South America and western Africa and speculated that those lands had once formed a supercontinent, Pangaea, which had split and slowly moved many miles apart over geologic time.
Who discovered seafloor spreading?
Harry Hess Harry Hess: One of the Discoverers of Seafloor Spreading.
What did Dan McKenzie discover?
plate tectonics Dan McKenzie published his first article on plate tectonics, providing a mathematical model for convection in the mantle explaining the movement of the earth's crust, “The viscosity of the lower mantle” (McKenzie, 1966).
Who were the two scientist who proposed the theory of seafloor spreading?
The idea that the seafloor itself moves and also carries the continents with it as it spreads from a central rift axis was proposed by Harold Hammond Hess from Princeton University and Robert Dietz of the U.S. Naval Electronics Laboratory in San Diego in the 1960s. The phenomenon is known today as plate tectonics.
What did Alfred Wallace discover?
Alfred Russel Wallace was born in Wales in 1823. He has been described variously as a naturalist, a geographer, and a social critic. He even weighed in on the debate as to whether or not life could exist on Mars. However, what he is best known for is his work on the theory of natural selection.
What was Erasmus Darwin known for?

What was Erasmus Darwin’s theory?
Darwin expounded one of the earliest theories of evolution (“all vegetables and animals now living were originally derived from the smallest microscopic ones”), and he described the importance of sexual selection to continuing changes within species (“the final cause of this contest among males seems to be, that the …

He was married twice – both times to women he adored – had an in-between mistress, fourteen children and dozens of lifelong friends. Erasmus also enjoyed his food.
What did Jean Baptiste Lamarck discover?
According to Lamarck, organisms altered their behavior in response to environmental change. Their changed behavior, in turn, modified their organs, and their offspring inherited those "improved" structures.
