The statement that does not belong to the theories of creationism and fixism in the provided options is:
B. Las especies de la naturaleza evolucionan con el tiempo. (Species in nature evolve over time.)
Explanation:
1. Creationism and fixism are theories that suggest that species were created in their current form and do not change over time.
2. In the context of these theories, the belief is that species do not evolve or change through a process of natural selection or adaptation.
3. Option B, which states that species in nature evolve over time, contradicts the principles of creationism and fixism by implying that species undergo evolutionary changes, which is not in line with these theories.
4. The other options (A, C, and D) align more closely with the concepts of creationism and fixism by emphasizing the idea of species being created in a fixed form and not undergoing changes or evolution.
Therefore, option B is the one that does not belong to the theories of creationism and fixism among the given statements.
