Question

difference between darwinism and lamarckism with suitable example

Answer 1

Lamarckism:
This theory states that there is an internal vital force in all organisms.It considers that new needs or desire produce new structures and change habits of the organism.According to this theory if an organ is constantly used it would be better developed whereas disuse of organ results in its degeneration.It does not consider struggle for existence.All the acquired characters are inherited to the next generation.Lamarckism does not believe in survival of the fittest.

 Darwinism
This theroy does not believe in the internal vital force.It contends that needs and/ or desires do not form part of Darwin’s natural selection theory.An organ can develop further or degenerate only due to continuous variations.Struggle for existence is very important in this theory.Only useful variations are transferred to the next generation.Darwin’s natural selection theory is based on survival of the fittest.​
