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 has been developed over time during its life to its offspring. Lamarck used the evolution of the giraffe to reinforce his idea. A trait was gained through their lifetime, which allowed them to adapt to the environment and pass onto future generations. Traits which weren’t necessary lessen in future. Also, his theory also explained that over time, creatures diverted ways to become a different species. Lamarck didn’t believe in extinction, …show more content…
Darwin’s theory was similar to Lamarck in a way because both believed that the traits of species can be passed down from one generation to the next. One of the main differences is that these traits were not derived from the environment shaping the organism’s genetic ability but from the chance of mutations and natural selection. “Natural Selection,” meaning the process whereby organisms better adapted to their environment tends to survive and produce more offspring. Darwin’s observations have a slighter variation between creatures of the same species which may give an advantage or disadvantage for a creature to survive. A good example of this is, if there are competing for food, the species which knows how to survive, reproduce which means there would be a higher chance of passing on traits to offspring for future generations. This gradually results in chances to general population of species like Lamarck’s theory. Changes will combine eventually to form a new
