James Hutton was born June 3rd, 1726, in Edinburgh, Scotland. He was a Scottish farmer and a naturalist, later in life he was known as the father of modern geology. (“James Hutton”, 2010) Hutton thought that sedimentation takes place so slowly that the oldest of rocks are made of, in his words, “materials furnished from the ruins of former continents.” The opposite happens when rock is eroded or decayed from weather or conditions of the area. He called this destruction and renewal the “great geological cycle,” and then realized that it had been happening for many years. Another one of Hutton’s theories was the Theory of Uniformitarianism. That was the idea that geological forces still at works today, were not that noticeable to people but they have a great affect on us, meaning that those forces still work the same as they did in the past. He died March 26th, 1797 in Edinburgh. (Mathez, 2000) Charles Lyell was born on November 14, 1797 at Forfarshire, Scotland. He was a Scottish lawyer, a geologist as well as a supporter of Uniformitarianism. He was the author of Principles of Geology. His theory was that earth must be very old and that throughout time the planet has undergone processes that change the shape the land. That includes erosion, earthquakes, glacial movements, volcanoes, and the decomposition of dead plants and animals. (Port, 2006) Thomas Robert Malthus was born on February 13th, 1766, at Dorking, a town south of London. His theory about population was that population growth usually exceeds the amount of food produced for that particular area, so we should try to limit the growth of our population.

Stephen Jay Gould was an American scientist of many different studies, such as: paleontology, biology, and was a historian of science. Most of his career was spent teaching at Harvard University and working for the American Museum of Natural History. Gould also taught biology and evolution at New York University. His biggest contribution to the progress of evolutionary theory, was his book, Rocks of Ages.
Charles Lyell Charles Lyell was a British lawyer and one of the smartest geologists known at his time. He was known as the author of the Principles of Geology, which helped popularize the theories and concepts of uniformitarianism. The Principles of Geology was the first book written by Lyell and explained the changes in the earth’s surface. He used the research and information in the book as his proof to determine that the earth was over 6,000 years old. The central argument in his book was “the present is the key to the past”, this meant that to find out what happened in the past you had to look at what was happening now.
"On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life," usually shortened to "the Origin of Species," is the full title of Charles Darwin's book, first published in 1859, in which Darwin formalized what we know today as the Theory of Evolution. Although Darwin is the most famous exponent of this theory, he was by no means the first person to suspect the workings of evolution. In fact, Charles owed a considerable debt to his grandfather Erasmus, a leading scientist and intellectual, who published a paper in 1794, calledZoonomia, or, The Laws of Organic Life. This set down many of the ideas that his grandson elaborated on 70 years later.

John Dalton was born on September 6 1766 at Eagelsfield, Cumbria in England.Although he was born in England, he spent most of his life in Manchester.He was born into a Quaker family and while his family had food, they were still poor. His father Joseph was a weaver and John recieved most of his early education from his father. At the age of 12, John opened a school in Eagelsfield where he was the master. He was often threatened by the older boys who wanted to fight him because he was smarter, but he managed to keep in control for 2 years.Due to a poor salary, John was forced to leave his school and work in the fields with his brother. In 1781 John and his brother moved to Kendall. There John, his cousin George, and his brother ran a school where they offered English,Latin,Greek,French and twenty one mathematics and science course. Their school had sixty pupils. After twelve years at Kendall John started doing lectures and answering questions for mens magazines. John found a mentor in John Gough,who was the blind son of a wealthy tradesman. John Gough taught Dalton languages,mathematics,and optics. In 1973 John moved to Manchester as a tutor at New College. He immediately joined the Manchester Literary and Philosophical Society and in the same year he published his first book: Meteorological Observations and Essays. In his book Dalton stated that gas exits and acts independantly and purely physically not chemically. After six years of tutoring, John resigned to conduct private research while still doing tutoring at 2 shillings a lesson. In 1802 John stated his law of partial pressures. When two elastic fluids are mixed together ( A and B) they dont repel each other. A particles do not repel B particles but a B particle will repel another B particle. One of his experiments involved the addition of water vapor to dry air. The increase in pressure was the same as the pressure of the added water. By doing this experiment, John established a relationship between vapor pressure and temperature. John’s interest in gases arose from his studies of meteorology. He had weather equipment that was with him at all times and he was constantly studying weather and atmosphere. He also kept a journal throughout his life in which he wrote over 200,000 observations. In 1803, John made his biggest contribution to science: The Atomic Theory.
“For decades ‘Burgess-Shale life’ was synonymous with ‘Cambrian life’” (Collins, 2009). This is since Cambrian life was only known from this place. According to Collins (2009) the first descriptions of Burgess Fauna were made by Joseph Whiteaves, a chief paleontologist who made the initial descriptions of Burgess Shale trilobites and unusual specimens which he called Anomalocaris (Collins, 2009). In 1907 Charles Dolittle Walcott, who is known to have discovered the Burgess Shale fauna visited the Canadian Rockies for the first time. His interest in fossils arose from a paper written by Henry Woodward where the author claimed that Cambrian fossils were probably found on Mount Field (in the Canadian Rockies) (Collins 2009). This led Walcott and his family to go to the place.
... Royal Society. He discovered numerous things about matters such as light and gravity, and in 1703 was elected as president of the Royal Society.
Charles Darwin has had the greatest influence on the world by proving the evolution of living things. Charles Darwin had first noticed the similarities of plants and animals when he took a five-year cruise on the H.M.S. Beagle, which was available to him through a friend from school. During the cruise Charles Darwin started becoming interested with the similarities between the plants and animals that were similar on different islands with similar climates, so he decided to study them more closely.

Percival Lowell was a well-known businessman, mathematician, author, and astronomer. He is the founder of the Lowell Observatory in Flagstaff, Arizona. He is also well known for popularizing the idea that Mars had life. His ideas had an immense impact on science fiction, as well as science itself. Not only that, Lowell’s search for “Planet-X” led to the discovery of Pluto.
Catastrophism taught that the geologic rock strata were primarily a result of catastrophes like the worldwide flood of Noah. At that time James Hutton and Sir Charles Lyell proposed an alternative explanation of uniformitarianism. The theory of uniformitarianism taught that the present was the key to the past and exactly the same slow process that we see today is the one responsible for the formation of all the geological rock
The chemist I did my project on is Humphry Davy. He was born on December 17, 1778.
In 1912 he first introduced the theory of the continental drift at a conference in Germany. He theorized that the continents had moved away from each other over a period of time and denied that land-bridges had existed to connect the continents. The same year he married the daughter of a meteorologist and returned on another expedition to Greenland. He went on to serve in the military during World War I. Although the idea about the continental drift had neve...

Thomas Robert Malthus, very popularly known as Malthus, was a professor of History and Political Economy at Haileybury College of the East Indian Company. He was a philosopher of 19th century. He lived his life from 1766 to 1834 AD. After writing an essay on the Principle of Population in 1805 AD, he became popular in the history of population studies. In his essay which later on became a very famous theory by the name "Malthusian Theory." In the theory, he has drawn some assumptions such as:
