Jean-Baptiste Lamark Proposed That Changes in the Traits of a Population

question 51

Multiple Choice

Jean-Baptiste Lamark proposed that changes in the traits of a population are a result of traits acquired during the lifetime of an organism being inherited by that organism's offspring. What is wrong with this proposal?

• A)Only changes in the DNA sequence of an organism can be inherited. Traits acquired throughout life generally do not involve DNA.
• B)The environment chooses which traits are necessary for survival rather than the individual.
• C)Changes in a species occur at the individual level rather than the population level.
• D)The inheritance of acquired traits would not lead to speciation because it would cause all of the individuals in a population to become more similar.
