How did lamarck contribute to the theory of evolution? a. he did not but instead proposed a concept known today as gene flow. b. he discovered genetic mutation through experiments with pea plants. c. he proposed the concept of natural selection after his voyage to the galapagos islands and his study of finches. d. he did not but instead proposed an erroneous evolutionary mechanism known today as inheritance of acquired characteristics.

d. He did not but instead proposed an erroneous evolutionary mechanism known today as inheritance of acquired characteristics.

Explanation:

Lamarck believed that organism changes as the environment change, and that those changes are passed to offspring ( inheritance of acquired characteristics). He also believed that if a certain structure isn't used by an organism it will gradually disappear through time.

According to Darwin's theory of evolution, natural selection is the main evolutionary mechanism. Darwin explains that organisms that have heritable traits that help them survive and reproduce, will be favorable by natural selection. Those favorable traits will enable organism to better adapt to their environment and to pass more genes on to the next generation (offspring).

Organisms adapt to their environment by changing their behavior, structural traits or physiology as a response to environmental change, so that they become well suited to it.
