which one of the following? 12. If Charles Darwin were to sit down to debate Jean-Baptiste Lamarck, which one of the following
arguments would Darwin be most likely to accept as sound?

A. Behind the theory of evolution is a preordained plan.
B. A giraffe’s neck gets longer when it must stretch to reach leaves higher up on a tree.
C. It’s likely that organisms, including bacteria, are always changing.
D. Experiences acquired by an organism are passed on to its offspring.
 
Answer C looks like the most reasonable answer. In contrast to what Darwin believed, Lamarck believed that the traits an organism acquired in its lifetime could be passed down to its offspring, which is false. In addition, Darwin's theory of natural selection cannot drive evolution by planning or creating new future traits, but instead it drives evolution by selecting for current traits that make organisms more advantageous in their specific environments.
