Question

How does the extension of the neck in Giraffe support Lamarck's theory of evolution?

Answer 1

Lamarck's theory of evolution:

1. The hypothesis of acquired character inheritance was put out by Lamarck.
2. According to the hypothesis, organisms adjust to their environment's changing conditions.
3. The organism's evolved traits are passed on to the following generation as well. This notion was shown with the aid of a well-known example using giraffe necks.
4. He saw that as generations passed, giraffes' necks became longer as they stretched their necks to reach the foliage on lofty branches.
5. The longer neck would be passed down through the generations in its descendants, and further stretching would result in an even longer neck.
6. The law of use and disuse is the name of this hypothesis.
