Question

Jean Baptiste Lamarck thought that species changed over time well before Darwin came around, and Lamarck even proposed a way that he thought it could happen! Briefly explain Lamarck’s idea and compare them to Darwin’s idea of natural selection. What is the major way in which they are different?

Answer 1

According to the Derwin's theory that all species of organism are arise and develop by the natural forces and increases the individual's ability to compete,survive and reproduce.

and Lamark's theory states that the more use of any oragan of the organism for natural changes leads to development of the organ and transmitted to the next generation.

So they both thought the same in a different way as the Darwins theory states that the spesies in the nature develops or increases individual's ability to compete among them but according to Lamark species develop and increases its ability to keep its existance in nature.

The major differences between the theory is the competetion between species for food,area,and mateing which is stated in Darwin's "Natural Selection Theory"but not in Lamark's thoery.
