Answer 2

So, you know Jean-Baptiste Lamarck hypothesis of the inheritance of acquired traits. Referred as Lamarckism. The first part of this was the theory of use and disuse; the idea that body parts used more often become stronger and larger, while parts not used slowly waste away and disappear.
Example is the femur bone of a whale and humans. A whale does not need this bone, meaning that it was acquired from a common ancestor. ((You could look up images of a femur bone of a whale in a diagram)).
Hope this helps! :)
