Explanation
Sentence 2 opens with adaptive behavior and cognitive economy (treating objects as equivalent). Sentence 4 elaborates on what treating objects as equivalent means (categorization). Sentence 3 shifts to how information from the world has structure, and sentence 1 provides a specific example of structure in living things. Thus, the correct sequence is 2431.
