Answer:

DIFFERENCES:

LAMARCK'S THEORY:

→Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.

DARWIN'S THEORY:

→Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.

SIMILARITIES OF LAMARCK'S THEORY AND DARWIN'S THEORY:

→Darwin and Lamarck's theories were very different but they were also very similar. They both thought that organisms changed. They thought these changes could be very useful and could help them survive. The changes could then get passed down to the young.
