Jean-Baptiste Lamarck Hypothesized That Changes Acquired During the Lifetime of an Individual

question 17

Multiple Choice

Jean-Baptiste Lamarck hypothesized that changes acquired during the lifetime of an individual organism, as a result of adapting to its environment, are passed on to progeny. Why was this incorrect but still important?

• A) Acquired traits are heritable, but not part of the genetic makeup of the organisms. Lamarck's idea was important because he was the first to propose a process for evolutionary change.
• B) Acquired traits are not heritable, but Lamarck's idea was important because he verified Darwin's process of natural selection.
• C) Acquired traits are not heritable, but Lamarck's idea was important because he was the first to propose a process for evolutionary change.
• D) Acquired traits are heritable, and Lamarck's idea was important because he proved Darwin's idea of variational evolution was incorrect.
