Aristotle/Plato- Aristotle was Plato’s student, they instructed that all organisms exist in a continuous sequence called “The Great Chain of Being,” or “Scala Naturae” This chain’s order consists of God, Angels, demons, man, animals, plants, and minerals. They also proposed that species are unchanging.
Nicholas Steno- Steno is known as the father of Paleontology, which consists of the studies of animal and plant fossils. Steno proposed that the layers of the Earth accumulated over long periods of time. He also proposed that layers were like snapshots of the Earth.
Motoo Kimura- In 1968, Kimura introduced “The Neutral Theory of Molecular Evolution”. He believed that most evolutionary changes were caused by genetic drift and not natural selection.
Jean-Baptiste Lamarck- Lamarck proposed the hypothesis of “inheritance of acquired traits.” Which proposes that body/behavior changes that were acquired throughout an organisms’ lifetime, can be passed on to its offspring. One of the most well-known examples, is that giraffe’s had short necks, and elongated over time.
George Louis Leclerc, Comte de Buffon- He focused on the encyclopedia “Histoire Naturelle” where wanted to organize every detail about the natural world. He only managed to publish 36 volumes before he deceased. In the volumes, he included drawings of the various scientific ideas such as botany and anatomy.
Georges Cuvier- Since he had a fossil record, he denied any theory which had to do with evolution. He is better
Francis Crick: Similar with Watson, Crick is also eager to finish the study as soon as possible. He is also one of the awardees of the Noble Prize.
Charles Darwin (1809-1882) was a British naturalist who became famous for his theories in evolution. He believed all species evolved form a common ancestor and that evolution happened through a process called natural selection, which meant survival of the fittest. In the BNW, the different castes of people were made from a common ancestor (a single individual). Thus, creating hundreds of his or her clones. Since the directors believed in survival of the fittest, they made the best kind of people so that they may live long in a specific environment.
Charles Darwin - traveled to Galapagos islands to study the Theory of Evolution that states that states that organisms adapt over time due to their environment
This book has been molded to be a breakdown of how various fields in science have progressed over centuries as mankind has advanced. The book starts off introducing the idea that the telling of natural history has changed numerous times as humans have evolved. We also learn to agree that our knowledge has been shaped by the tools available and the perceptions of its users. In the earliest stages of life, Muehlbauer states “…observers of the natural world had only their senses to work with, and were limited to visual, auditory, tactile, and olfactory descriptions perceived by the unaided
At the beginning of the 1800s, scientists knew of some kinds of fossils, and were very aware of homologous and vestigial structures. Many scientists suspected that some kind of evolution had given rise to living things around them. However, they had no theory to explain how evolution might have occurred. Two scientists led the way in the search for a mechanism of evolution. The first was Jean Lamarck. The second was one of the greatest figures in biology, Charles Darwin.
Along with Auguste Comte, another influential philosopher and scientist was Charles Darwin. Darwin presented the idea of natural selection and evolution in the 19th century. Darwin said that variations within a specific species will kill off the weaker members will die off and the stronger members will survive, based on Malthus' theory that population will always outgrow the amount of supplies.
Charles Darwin proposed that the mechanism of evolution is natural selection and that it explains
(D) - Charles Darwin wrote “On the Origin of Species by Means of Natural Selection”, published in 1859. His book explained the theory of evolution, and the process of natural selection. Darwin’s work was met with much dissent at the time of its release, as what he proposes directly conflicts with many Christian beliefs on the creation of the world. Today, the
The late Stephen Jay Gould, a noted paleontologist who once described himself as an “agnostic leaning towards atheism,” wrote the classic treatise Evolution as Fact and Theory for Discover magazine back in 1981. His distinguished career and scientific achievements did earn him respect amongst his peers, but to the general public he is best known for his popular science writings and, to smaller circles, as a champion of evolution. As his treatise was written for a non-academic, science themed magazine, a basic understanding of science, and specifically evolutionary mechanics, was assumed of his audience. The treatise itself is on the often overlapping distinction between “theory” and “fact”; two words, he asserts, that creationists
For example, Galileo, an Italian scientist made one of the first telescopes. He observed the sky and rightly believed that he was able to confirm Copernicus’s theory(Alchin); he turned the telescope to the Heavenly bodies and observed that the sun moves on its axis, Venus shows phases according to her position with the sun. He also believed that Jupiter had revolving moons or satellites that moved around it, and the Milky Way was composed of a multitude of separate stars(Alchin). Another scientist was Kepler; he worked out the mathematical laws that govern movements of planets, and made it clear that the planets revolve around the sun in an elliptical orbit instead of circular orbits. His investigations later led to the discovery of the principle of gravity(Alchin). Vesalius was a scientist, who gave the world the first careful description of the Human Body based on actual dissections and was the founder of human anatomy, which has become an important part of health in today’s society(Alchin). Additionally, Harvey was an Englishman who observed living animals and announced the discovery of circulation of blood in the body. He founded Human Physiology, which greatly impacts us even today(Alchin). Furthermore, magnetism was a large discovery that had a big impact during the Elizabethan Era and times to
The Scientist I read about was Zhang Heng. Zhang Heng was a Chinese mathematician, astronomer, and geographer. He was also a cartographer, artist, poet, statesman, and a literary scholar from the Henan Province, Nanyang in China. He is well-known for Chinese inventions in which he invented. Zhang hang was born at 78 CE in a town located north of the modern Henn Province, Nanyang City. He died in 139 CE at Luoyang, China. Zhang Heng came from a distinguished family that isn't affluent.
Charles Darwin and Alfred Wallace like so many of their predecessors made observations of natural phenomena that inspired proposals of how life on earth evolved, unlike others these men formed plausible explanations of how the changes in populations occurred without having any knowledge of Mendelian genetics which was presented in 1868, and provided the micro-mechanism for evolution that Darwin could never explain with his theory of Pangenesis. Rather, based solely on the observations each made over time observing different species of populations around the world, both men were able to pen the ideals that would serve as the foundation of the modern theory of evolution.
During the time when Charles Darwin was alive (1809-1882) most of the Western culture believed that the world was created by God and only several thousand years old. They believed that our world was always like it was then. So when Darwin wrote The Origin of Species it shook up both the cultural and scientific views of his time. His views that evolution occurs by natural selection was one of the most radial theories during his time, yet today is widely accepted as a fact among most of the world.
Jean-Baptiste Lamarck (1755-1829) is one of the best-known early evolutionists, holding a belief that evolution was a continuous development and strived toward greater complexity and perfection. Through which, his theory of evolution was that living organisms evolved in a unceasingly up ward direction, from dead matter, through simple to more complex forms and towards human “perfection” (Nesci.edu, 2015). From his theories of Inheritance of Acquired Characteristics; where organisms adapt to their environments and those changes were passed onto their off springs (Corbis, 2001), to his theories of Use and Disuse, where organisms that are not used progressively disappear (Evolution.berkeley.edu, 2015). Lamarck was the first biologist to publish
Many knowledge claims in human and natural science are based on theories. Jean Lamarck proposed the theory of evolution in 1801. The theory of evolution proposed by Lamarck was based on the idea that organisms had to change their behavior to survive. For instance, if a giraffe stretched it neck for a long period of time to reach the leaves as the top of the tree, then a “nervous fluid” would flow in the neck and make it longer. Thus, its
