Development of Evolution: Timeline of theorists

  • Erasmus Darwin scientific work part two

    Zoonomia is a complex theory about the laws of organic life, and the modern theory of evolution supports Erasmus’ views. Even though Erasmus wasn’t able to prove most of his theories, he was able to create a starting point for all evolutionists/naturalists.
  • Erasmus Darwin influences part one

    Influences- Erasmus translated an entire piece written by a botanist named Carolus Linnaeus from Latin to English. Erasmus must have been strongly interested in Carlous’ work, which could have influenced him to research more on botanical work.
  • Erasmus Darwin influences part two

    Erasmus based most of his theories from Zoonomia on David Hartley’s psychological theory of Associationism, which suggests that sensations are the primary basis of meaning. In Zoonomia Erasmus proposes that all organisms started the same but through different irritations and sensations that organism will change and forever change in different ways.
  • Erasmus Darwin scientific work part one

    Scientific work- Erasmus’ most important scientific work was Zoonomia. Zoonomia was a book with two additions that Erasmus wrote in the time period of 1794-1796. Erasmus’ theory was that all life had evolved from one common ancestor, which over time branched off into all the different species we see today. He also thought that transmutation of species was driven by competition in organisms.

    William Paley

  • JEAN-BAPTISTE LAMARCK scientific work part 1

    Scientific work-Lamarck’s most important work was on evolution. His theory was that organisms adapt to their environment. He proposed that an organism could move up the ladder of evolution to make it more adapted to its environment or that an organism can be so adapted to its environment that nothing will change. He stated that the force behind adaptation was the interaction of the organism and its environment. Lamarck also had two laws.
  • JEAN-BAPTISTE LAMARCK influences

    Influences-Georges-Louis Leclerc was a French naturalist, biologist. He was one of the first people to believe that species could evolve over generations. He also thought that natural phenomena must be explained by natural laws instead of theological doctrine.
  • JEAN-BAPTISTE LAMARCK scientific work part two

    In his first law he believed that if an organism uses a particular organ it will strengthen over time, but if it stops using a particular organ than it will slowly deteriorate and disappear. In his second law he suggests that the habitat that an organism lives in influences the organism’s evolutionary path. And that it will be passed down to both male and female.

    Jean Baptiste Lamarck

  • William Paley influences

    Influences- William Paley was manly influenced by Philosophers like John Locke, Joseph Butler and Samuel Clarke. He was also influenced by his up brining; William Paley was brought up in a very religious family, this would have given him some reason to prove that god existed and also to prove the atheists wrong.
  • William Paley scientific work part two

    So William Paley was a scientist and also believed in god like many others from the time. But William Paley also thought that he could prove gods existence as well. This was inevitably unsuccessful.
  • William Paley scientific work part one

    Scientific work- Paley’s most significant work was his book, Natural Theology. Charles Darwin even claims that he was heavily interested in what the book had to say about evolution. Paley had an analogy called the watchmakers analogy. The watchmakers analogy claims that design implies a designer. This supported the argument of god and an intelligent design of the universe.

    John Henslow

  • Charles Lyell scientific work part two

    Lyell also supported the theory of natural selection even though he denied it in the public eye. Lyell taught Darwin geology and Darwin claimed that his theory of slowly changing organisms also need slowly changing environments. Darwin also used the knowledge that he had learnt from Lyell, on his expedition on the Beagle.
  • Charles Lyell influences part two

    A lecturer named William Buckland had also influenced the young Lyell when he had attended Oxford College. Lyell was influenced to join the Geological Society and get a better understanding of geology.
  • Charles Lyell influences part one

    Influences- Lyell had many influences. A theory that he supported (uniformitarianism) had derived from the work of James Hutton, which he would have admired. Another person who had a strong influence on him was Lamarck, because Lyell didn’t believe in Lamarck’s theory of organic evolution. This would have made Lyell seek the truth, he proposed and another idea, centres of creation.
  • Charles Lyell scientific work part one

    Scientific work- Charles Lyell studied stratigraphy, glaciology and paleontology. Charles Lyell was a strong enthusiast of uniformitarianism. Uniformitarianism is the hypothesis in which the process of how the universe changes is continually happening. In Lyell’s Principles of Geology he was able to explain what caused earthquakes.

    Robert chambers

  • Robert Chambers scientific work part two

    He also believed in transmutation of species, which is the altering of one species in to another that is more evolved. This book was so informative that Charles Darwin claimed that he wouldn’t have been able to write the origin of species.
  • Robert chambers influences

    Influences- Jean Baptiste Lamarck was a heavy influence on Chambers because chamber’s work was so similar to that of Lamarck’s. Lamarck gave a brief theory on what he thought evolution was and Chambers was able to get more information and give Lamarck’s theory more weight.
  • Robert Chambers scientific work part one

    Scientific work- Robert chambers released a book in 1844 called Vestiges of the natural history of creation. By far his most important work, during publication, Chambers didn’t claim to have written it because most of the scientific community disliked the theory of evolution. Chambers thought that this book was the first to connect the natural science in a history creation. In this book he believed in stellar evolution, which is the process that stars go through resulting in major changes.

    Slowly their biological traits will let them become more dominant in a particular environment. There are always going to be variation in a population due to mutation in an individual.
  • Charles darwin scientific work part three

    During his time on the Galapagos islands he saw a breed of finches that were also in south America, but in south America there was only one breed and in the Galapagos islands there were many. This prompted Darwin to investigate and he found out that all of the different breeds of finches were adapted to their particular environment. All with slight mutations that made diversity possible.
  • Charles Darwin influence part one

    Influences-Charles Darwin’s main influence was his grandfather Erasmus. Which Charles Darwin extended on his grandfathers work about asexual reproduction and the early theories of natural selection.
  • Charles Darwin influences part two

    Alexander von Humboldt also influenced Charles Darwin. Alexander was a geographer, naturalist and explorer, much like how Charles Darwin was. Alexander also laid the foundation for the field of biogeography.
  • Charles Darwin influences part three

    Charles Darwin also admired John Herschel’s work in natural philosophy and inductive reasoning. This inspired Charles Darwin to follow in the field of natural philosophy. This inspiration came to him at Cambridge University were John’s ideas were taught.
  • Charled Darwin influences part four

    Charles Lyell was an influence to Charles Darwin but also a friend. He published the Principles of Geology that made him the best geologist of his time. Lyell’s theory that the earth’s geological change is an accumulation of small changes over vast time periods had a major influence over Charles Darwin.
  • charles Darwin scintific work part one

    Scientific work- Charles Darwin worked closely to the evolution of animals and organisms. Charles Darwin spent many years on a boat named the Beagle, on this expedition Charles Darwin found lots of interesting things when he reached the Galapagos Islands. Charles Darwin’s most important theory was called natural selection, he proposed that organisms better adapted to their environment tend to survive, and then the survivors offspring have a better chance of survival.

    Alfred Wallace

  • Alfred Wallace influences part one

    Influences- Alfred’s major influence was Robert chambers and his work on vestiges of the natural history of creation. Alfred resembled chambers with both of them having highly controversial work.
  • Alfred Wallace scientific work part two

    Evolutionary talk was frowned upon by most scientist because of the suggestions it made. But when Alfred and Charles realized their work was similar they were able to publish it together. Because two leading scientist had the same idea many people gave a chance to read into there theory of evolution.
  • Alfred Wallace scientific work part one

    Scientific work- Alfred Wallace was a leader of evolutionary thinking in the earlier days. One of his best friends and partners for evolutionary thinking was Charles Darwin. They both had the same theory and found out when they were writing to each other from far.
  • Alfred Wallace influences part 2

    Charles Darwin would have also been a major influence in Alfred’s life, because of their similar theories would have boosted Alfred’s confidence in the work on evolutionary thinking. And possibly could have led to Alfred’s expeditions to the south American forest. Where he had hoped to simulate evolution taking place.
  • John Henslow scientific work part two

    Henslow had a passion for botany and that took up most of his time, but he was able to collect large variety of flowers to group them into species. He later started to experiment on the flowers to see what limit of variation occurs under different environments. This work was successful and was published as a textbook.
  • John Henslow influences part one

    Influences- Henslow had a passion for natural history from a very young age, and this influenced him to take up the career of science. His chemistry teacher was Professor James Cumming and Mineralogy teacher Edward Clarke.
  • John Henslow influences part two

    John Henslow’s protégé was Charles Darwin. Charles accompanied Henslow on many of his expeditions, Henslow must have seen himself in the young Charles Darwin because he gave up his spot for the Beagle voyage to let Charles go.
  • John Henslow scientific work part one

    Scientific work- John Henslow was a botanist and geologist. He went on a tour in 1819 to the Isle of Wight where he had his first real lesson in geology. He went on other expeditions and latter printed his findings to the Cambridge philosophical society in 1822. Later on in his career he became a Professor at Cambridge and pass all of his knowledge to Charles Darwin.
