What Was Lamarck's Theory Of Evolution?

Answer Question

8 Answers - Sort by: Date | Rating

    Jean-Baptiste Lamarck lived from 1744 until 1829 and was a scientist from France. He lived before Charles Darwin (1809 – 1882) and was also interested in how organisms had developed into the form that they had. His ideas were the start of scientists thinking about evolution but he did manage to get it wrong in a rather major way.

    He thought that animals and plants adapted to their changing surroundings in their lifetime and then passed on these changes to their offspring. The classic example that he cited was a giraffe – he said that a giraffe's neck got longer as it stretched for leaves higher up on trees. This made its neck and bit longer, so its offspring had necks a bit longer too.

    This theory, often called Lamarckism, is a mistake often repeated by biology students when they first learn about evolution. The true mechanism of natural selection was explained by Darwin and others a few decades later.

    He believed that giraffes have long necks because they have to strech upwards to reach the leaves on the high trees. Lamarck said that the stretched neck of the giraffe would be passed on to it's children and that this explained the gradual lengthening of the neck of the giraffe over many years.

        Lamarck's theory can be described in one sentence: The function creates the organ. He believed that organisms tried to make themselves better in their lifetimes and these improvements were passed onto their offspring. This theory has been disproved by Darwin who gave a more reasonable theory.

        He believed that for example all giraffes had short necks and stretched them out themselves to reach for food or something....

          That life evolved from simple organisms which then developed into more complex organisms.
