Concepts more than theories. Use and disuse. A anatomical part of an organism would fade away if not constantly used and would enhance itself is used. The giraffe neck as an example of use.

What are the differences between Darwin's and lamarcks theory of evolution?
Larmark's theory was based on the idea that organisms inherited characteristics that they had acquired in life - so, if you have a scar your offspring will have scars. Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.
How was Darwin's theory of evolution different from lamarcks?
In Darwin's theory, natural selection plays the key role. Organisms vary through random mutations--slight changes from their parents. The environment determines which are most likely to survive. In Lamarck's theory, changes in phenotype are inherited. This is now known to be (largely) incorrect.
