Detailed explanation-1: -It is correct that evolution occurs over generations of reproduction, but Lamarck was incorrect in thinking that traits developed over a lifetime will be passed along to offspring. The correct mechanism of inheritance is that genes are passed along from generation to generation.

Detailed explanation-2: -Lamarck’s Theory of Inheritance of Acquired Characteristics has been disproved. This was done in two major ways. The first is by experiment. We have seen through many real examples and observations that changes that occur in an animal during life are not passed on to the animal’s offspring.

Detailed explanation-3: -Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth. And biologists have identified and investigated mechanisms that can explain the major patterns of change.

Detailed explanation-4: -Which of his ideas is correct? Explanation: While Lamarck had many revolutionary ideas on evolution, his most correct assumption was the importance of environmental changes on evolutionary adaptations.
