There have been many ideas on the theory of evolution. Some simply take our existence for granted. there are those who have researched the topic of evolution and have offered an explanation as to where a species comes from and how they evolved in the manner that they did. This type of science has been studied for a very, very long time and one of the most famous minds in the field of evolution was a man named Charles Darwin. One of the early pioneers was Lamarck. it was Darwin himself who said that Lamarck was the first man whose conclusions on evolution. He was the one who showed law in organic and inorganic species evolution
Lamarck is best known for his THEORY OF INHERITANCE OF ACQUIRED CHARACTERISTICS, first presented in 1801(Darwin’s first book dealing with natural selection was published in 1859).if an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring. He said’ CHANGE IS MADE BY WHAT THE ORGANISMS WANT OR NEED’. He believed that elephants all used to have short trunks. When there was no food or water that they could reach water and branches, their offspring inherited long trunks. He believed that evolution happens according to predetermined plan.
Darwin believed that evolution does not happen according to any sort of plan. Darwin stated that’ ORGANISMS EVEN OF THE SAME SPECIES,ARE ALL DIFFERENT AND THOSE WHICH HAPPEN TO HAVE VARIATIONS THAT ASSIST THEM TO SURVIVE IN THE ENVIROMENT OF THEIR HABITAT SURVIVE AND HAVE MORE OFFSPRING’. As many people dislike the taste. The natural selection in this case is the students’ preference for non-black beans. More black jelly beans therefore survive predation, or selection, by students. Luckily black jelly beans are unable to pass down their traits to the next generation. The desires of animals have nothing to do with how they evolve, and changes in an organism and its life do not affect the evolution of the species.
Darwin and Lamarck’s theories were very different. Darwin theory said that organisms get helpful variation before changes in the environment. He thought they got the variation by chance at birth. He explained that the reason giraffes had long necks was because some giraffes had a variation which was a longer neck. The...
