    existence, inheritance and variations, and survival of the fittest. It can be explained that the reproduction of organisms always exceeds the carrying capacity of the environment. Besides, the intraspecific competition happens such as the struggle for food, mates, and habitats. Also, the variations of organisms are beneficial for survival but sometimes they are counteractive. Moreover, after the struggle for existence, all surviving species have the superiority in adaption to environment. After reading, I find that Lamarck’s theory has the difference from Darwin’s Theory of Natural Selection. They have opposite views on how organisms adapt their environment. The textbooks writes, “According to the classic (though incorrect) example of Lamarckism, giraffes stretched to reach food at the tops of trees, their necks grew as a result, and they passed on these long necks to their offspring” (Larson 30). This example shows that Lamarck proposed that organisms could keep developing as the environment changes, and their traits could pass on to their offspring. On the other hand, Charles Darwin had more progressive ideas about evolution, “Darwin deduced that natural selection was the primary mechanism of evolution. Over a long period of time, through generations’ adaption to different environments and different foods, a common ancestor gave rise to related species…Now, species would have to be considered as populations with no predetermined limit on variation” (Larson 31). It shows…

  • Impact Of Evolutionary Psychology

    Darwin established one of evolutionary psychology’s most important ideas, which continues to influence how we view our behaviour and mental abilities, as well as those of other animals (Montgomery, 2001). It also allows us to discover how behavioural traits such as phobias and mate retention strategies have evolved, even if they are not adaptive today. The mind is now evolving culturally rather than biologically by imitation of memes. Archer (2001) argues that even the theory of evolution itself…

  • What Is Neo-Darwinism?

    Evolutionary biologists such as Richard Dawkins1 , Paul Meyers2, and Jerry Coyne3, and philosophers of science such as Daniel Dennett4, Micheal Ruse5, and Peter Singer6 have produced differing defences and explanations of Darwinism, its roots, and its various implications within a Neo-Darwinian framework. In many cases, these have been intended for wider consumption beyond academia and have incorporated the promotion of Darwin as a unique historical agent, with Dawkins arguably leading the pack…

  • Modern Day Theory Of Evolution Essay

    Charles Darwin’s developed a theory of Pangenesis, while similar to prior theories of Lamarckism, it has slight differences. While the differences might be subtle they are big enough of differences to classify them as different theories. The theory of Lamarckism states that we evolve from experiences in our lifetimes, and that those traits are carried onto our offspring, this idea is otherwise known as Soft Inheritance. For example, say a weightlifter built his muscle mass throughout his life,…

  • The Adaptation Of Alfred Wallace's Evolutionary Theory

    just as similar to that of Charles Darwin. Variations are the key concepts that are studied in both of Wallace’s and Darwin’s. The reason this is done is, because variations help to identify why the species evolve. Wallace’s theory does differ from Darwin 's. Wallace’s theory shows that a species will only take on an adaptation if it will be beneficial to the species survival. Now, for the evolutional theory the adaptation is not just a biological factors it is can also be behavioral factors. It…

  • Analysis Of Lamarck's Theory Of Deprivation

    Lamarck described that living beings acquired traits during the course of their lives based on the needs of the organism, and these traits could then be passed on to the offspring of the organism. For example, according to Lamarckism, a giraffe has a long neck because initially, the giraffe wished for a long neck in order to feed on tall plants, and over the course of the giraffe’s life, its neck progressively lengthened as a result. This “change” would then be passed onto the giraffe’s…

  • Charles Darwin's Naturalistic Ideas

    Grant was conservative on the outside, but adventurous in his thoughts. He was the teacher of invertebrate anatomy in Edinburgh. He selected students that he wanted to specifically mentor, and one of these students was Darwin. While they were out together one day, Grant spoke all about Lamarck and his evolutionary theory. Even then Darwin looked at Lamarck’s theory with resistance. Darwin ran into Lamarckism again on the Beagle voyage, when he read the second volume of Lyell’s Principles of…

  • Natural Selection: Main Driving Force Of Evolution

    The only problem that many scientists had with Darwin’s theory of Evolution, was that they didn’t believe that Natural Selection was the main driving force of Evolution. Everyone at this point, even theologians, accepted Evolution. However, since a lot of people disagreed with Natural Selection, this gave rise to different alternatives to explain the variations of species. Additionally, many naturalists who came up with the different alternatives, the methodology of Natural Selection didn’t…

  • Essay Comparing Darwin And Lamarck

    Charles Darwin and Jean-Baptiste Lamarck were two most influential theorists who both lived in the 19th century. The two naturalists, Darwin and Lamarck, produced a theory of evolution which both had definite similarities and differences. The term, ‘evolution,’ is how different types of organisms are developed over generations. Jean-Baptiste Lamarck was a French biologist (1744 – 1829) who created his theory based on Lamarckism, which is his idea when an organism can pass on characteristic that…

  • Comparing Darwin And Lamarck's Theories Of Evolution

    evolution. Lamarck’s theory was oriented around how organisms change according to their surroundings during their lifetime and pass these traits onto their offspring. While Darwin’s theory, known as natural selection, believed that each organism has a differential ability to survive and reproduce due to variation in characteristics. This is why the term “survival of the fittest” was coined. These characteristics will then be more likely to appear in the next generation. Darwin proposed that the…
