Question

The degenerated wing of a kiwi is an acquired character. Why is it an acquired character?

Answer 1

1. When there is a change in the environment, the animals respond to the change.
2. They develop adaptive structures. The characters developed by animals during their lifetime, in response to environmental changes, are called acquired traits.
3. Lamarck's theory of use and obsolescence states that if an organ is used continuously, it develops well and strengthens itself. When an organ is not used for a long time, it gradually degenerates.  

The degenerate wing of the kiwi is an example of an organ in disuse

The degeneration of wings in kiwifruit is due to the disuse of wings over generations as they have learned to walk the land for all their needs. It is a character acquired in response to their habitat. According to Lamarck, these characters are transmitted to sources by inheritance.
