Jean-Baptiste Lamarck

Darwin was not the first scientist, proposing that the species evolve and change throughout the time. In the end of XVII century, paleontologists started to use fossils in order to explore the past of the nature. One of the scientists, Jean-Baptiste Lamarck was the first one to propose a theory of evolution. Lamarck’ theory was based on his observations and the idea, that a species’ goal inlaid by nature is to meet an increasing complexity. He was the first scientist to introduce the word "evolved" in a modern sense (Jameson, 1826). However, there were many flows in his theory. Which contributed to a strong opposition from the scientific world.
Jean-Baptiste Lamarck, born in 1744, in Bazentin le Petit. Being officer in the army, Lamarck was injured and decided to dedicate his life to medicine. His interest in simple organisms and the observation of the relation between the fossils and modern organisms led to the conclusion, that the species become more and more complex over the period of time. Lamarck’s theory states, that the evolution is a product of acquired characteristics from parents together with the universal principle forcing the species to increase their complexity. In his understanding, individual organs in an organism can strengthen or weaken, depending on the regular use. Those characteristics are then being transmitted to the species’ offspring.
One of the major laws of Lamarck’s theory state, that in every animal, frequent and
